Amana Furnace Error Codes — Meanings, Causes & Repair in Greater Vancouver

Seeing a fault code on your Amana furnace? This guide explains what the most common Amana furnace error codes mean, what’s safe to check yourself, and when to call HeatLand’s licensed, TSBC-certified gas technicians for Amana furnace repair across Metro Vancouver and the Fraser Valley.

The codes below apply across common Amana models (AMVC, AMSS, ACVC, AMS8, AMH95, AMV9). Meanings follow Amana’s documented fault codes — always confirm against your unit’s own manual, because exact wording can vary by model, control board and firmware.

How to read Amana furnace error codes

Amana furnace diagnostic LED flash codes (single-LED control board; flash patterns viewed through the blower-door observation window). Newer communicating/modulating models (e.g. AMVM97) instead show alphanumeric status codes on a 7-segment display.

Amana furnace error codes & what they mean

These are the Amana furnace codes our Greater Vancouver technicians see most. Anything marked pro repair involves gas, electrical, sealed-combustion or control-board work that must be done by a licensed gas technician (TSBC-certified in BC) — never open gas or electrical components yourself.

Code	What it usually means	Common causes	Safe to check yourself
LED OFF (no light)	No power: no 115-volt power to the furnace, or no 24-volt power to the integrated control module pro repair	Furnace switch or breaker is off; Blower-compartment door switch not engaged (door open or loose); Blown fuse on the control board (often from a wiring fault)	Confirm the furnace switch (looks like a light switch on or near the unit) is ON; Check the home breaker panel and reset the furnace breaker once if tripped; Make sure the blower-compartment door is fully closed so its safety switch engages
LED ON, steady (not flashing)	Normal operation: control module has power and detects no fault DIY-checkable	No fault present; this is the healthy state; If no heat with a steady-on LED, the issue is usually outside the diagnostic circuit (thermostat call, gas supply, or airflow)	Set the thermostat to Heat and above room temperature to confirm a call for heat; Replace thermostat batteries if it has them and the screen is blank; Check that the furnace gas shutoff is on and other gas appliances (stove, water heater) work
Rapid / continuous flashing	Reversed 115 VAC line-voltage polarity (line and neutral swapped) or improper grounding. Reported as 'Reverse polarity, check wiring diagram' on single-LED Amana/Goodman boards pro repair	Line (hot) and neutral reversed at the furnace or at the outlet/junction supplying it; Missing or poor equipment ground; Recent wiring work done incorrectly	Note the code for your technician; this is a 120V wiring issue; Do not open electrical boxes or rewire — diagnosis requires a meter and licensed work
1 Flash	Furnace lockout due to an excessive number of ignition retries (typically 3). The control automatically attempts to reset from lockout after one hour pro repair	No gas to the burners (interrupted gas supply); Weak, cracked, or misaligned hot-surface igniter; Dirty or oxidized flame sensor (flame not proven)	Confirm the gas is on and other gas appliances in the home work; Replace a clogged air filter, which can cause nuisance lockouts; Power-cycle the furnace once (switch off ~30 seconds, then on) to clear lockout
2 Flashes	Pressure switch circuit is closed (stuck closed) while the induced-draft blower is not operating, i.e. the pressure switch is closed when it should be open at the start of the cycle pro repair	Pressure switch stuck closed or shorted; Induced-draft (inducer) blower not running; Wiring fault shorting the pressure-switch circuit	Power-cycle the furnace once to see if the code clears; Note the code for your technician — internal switch/inducer diagnosis is not a homeowner task
3 Flashes	Pressure switch circuit is open (not closed) while the induced-draft blower is operating. Often reported simply as 'open pressure switch.' pro repair	Blocked or restricted intake or exhaust (flue/vent) terminal; Condensate drain blockage causing the switch to open (90%+ models); Weak inducer motor or disconnected pressure-switch hose	Go outside and clear snow, ice, leaves, or debris from the intake and exhaust vent terminals; Make sure nothing (nest, bag, frost) is blocking the vent pipes; Power-cycle the furnace once after clearing any blockage
4 Flashes	Open high-limit switch (primary limit open), usually caused by the furnace overheating pro repair	Dirty or clogged air filter restricting airflow; Blocked supply or return registers/ducts; Failed or slow blower motor	Replace a dirty air filter (the single most common cause); Make sure supply and return vents/registers are open and not blocked by furniture or rugs; Power-cycle the furnace once after replacing the filter
5 Flashes	Flame detected (sensed) when no flame should be present — e.g. a call for heat is not active or the gas valve is commanded off. Indicates a possible slow-closing or leaking gas valve pro repair	Gas valve closing slowly or leaking by; Lingering flame or hot residual sensed after shutoff; Control board misreading the flame-sense signal	Note the code for your technician — this involves the gas valve and must not be serviced by a homeowner; Power-cycle the furnace once to confirm the code persists
6 Flashes	Open rollout (flame rollout) limit switch. On some single-LED Amana/Goodman boards this position is skipped; where present it indicates the rollout safety has tripped pro repair	Flame rollout caused by a blocked or restricted flue/heat exchanger; Cracked primary heat exchanger or plugged secondary heat exchanger; Dirty burners	Turn the furnace off and call a licensed technician — a tripped rollout switch can indicate a combustion or heat-exchanger problem; Do not attempt to reset the rollout switch yourself
7 Flashes	Low flame signal / faulty flame sensor (flame current below the required threshold) pro repair	Dirty, oxidized, or coated flame sensor; Poor sensor positioning in the flame; Weak burner flame from low gas pressure or partial blockage	Confirm the gas is on and other gas appliances work; Power-cycle the furnace once; Note the code for your technician — flame-sensor cleaning is an internal burner-area task for a tech
8 Flashes	Igniter fault or improper grounding (hot-surface igniter circuit problem) pro repair	Cracked, worn, or open hot-surface igniter; Loose igniter wiring connection; Improper control or chassis grounding	Power-cycle the furnace once to confirm the code; Note the code for your technician — igniter replacement is an internal electrical task
9 Flashes	Reversed line-voltage polarity or grounding fault on single-LED flash-count boards. NOTE: on newer communicating/modulating controls (e.g. AMVM97) the equivalent 'EA' code instead means 'high-stage pressure switch stuck open' — confirm against the chart on your furnace's access-panel label pro repair	Line (hot) and neutral reversed at the furnace supply; Missing or poor equipment ground; On two-stage models: high-stage pressure switch stuck open (vent/inducer high-fire restriction)	Clear any snow/ice/debris from the outdoor intake and exhaust vent terminals; Note the code for your technician — 120V wiring and pressure-switch diagnosis require a licensed tech
E1 (alphanumeric, communicating models)	Lockout due to excessive retries or recycles pro repair	Repeated failed ignition or flame loss (same root causes as the 1-flash lockout); Gas supply interruption; Weak igniter or dirty flame sensor	Confirm gas is on and other gas appliances work; Replace a dirty air filter; Power-cycle the furnace once to clear lockout
E2 (alphanumeric, communicating models)	Low-stage pressure switch stuck closed at the start of the heating cycle pro repair	Pressure switch stuck closed; Inducer not running; Wiring/short in the pressure-switch circuit	Power-cycle the furnace once to see if it clears; Note the code for your technician
E3 (alphanumeric, communicating models)	Low-stage pressure switch stuck open pro repair	Blocked intake/exhaust vent terminal; Condensate drain blockage; Weak inducer or disconnected pressure hose	Clear snow, ice, or debris from the outdoor intake and exhaust vent terminals; Power-cycle the furnace once after clearing any blockage
E4 (alphanumeric, communicating models)	Open high-limit switch (overheat) pro repair	Dirty air filter restricting airflow; Blocked supply/return vents; Failed blower motor	Replace a dirty air filter; Open and unblock supply and return vents/registers; Power-cycle the furnace once after replacing the filter
E5 (alphanumeric, communicating models)	Flame detected when no flame should be present pro repair	Gas valve closing slowly or leaking by; Control misreading the flame-sense signal	Power-cycle the furnace once; Note the code for your technician — gas-valve issue, not a homeowner task
E6 (alphanumeric, communicating models)	Open fuse on the control board pro repair	Short in the low-voltage (24V) thermostat or accessory wiring; Failed component drawing excess current; Pinched or grounded control wire	Note the code for your technician — a blown board fuse points to a wiring short that needs diagnosis
E7 (alphanumeric, communicating models)	Low flame signal pro repair	Dirty or oxidized flame sensor; Weak burner flame; Grounding issue	Confirm gas is on and other gas appliances work; Power-cycle the furnace once; Note the code for your technician
E8 (alphanumeric, communicating models)	Igniter fault or improper grounding pro repair	Cracked or open hot-surface igniter; Loose igniter connection; Improper grounding	Power-cycle the furnace once; Note the code for your technician
E9 (alphanumeric, communicating models)	High-stage pressure switch stuck closed at the start of the heating cycle pro repair	High-stage pressure switch stuck closed; Inducer fault; Wiring/short in the high-stage pressure-switch circuit	Power-cycle the furnace once; Note the code for your technician
EA (alphanumeric, communicating models)	High-stage pressure switch stuck open pro repair	Restricted vent/intake at high fire; Weak inducer at high stage; Failed high-stage pressure switch	Clear snow, ice, or debris from the outdoor intake and exhaust vent terminals; Power-cycle the furnace once after clearing any blockage
EC (alphanumeric, communicating models)	Reversed 115 VAC polarity pro repair	Line (hot) and neutral reversed at the furnace supply; Missing or poor equipment ground	Note the code for your technician — 120V wiring must be checked by a licensed tech
Ed (alphanumeric, communicating models)	Inducer motor overcurrent fault pro repair	Failing or binding inducer motor; Restricted venting increasing inducer load; Inducer wiring fault	Clear any blockage from the outdoor vent terminals; Note the code for your technician
EF (alphanumeric, communicating models)	Rollout switch open pro repair	Flame rollout from a restricted flue or dirty burners; Cracked primary or plugged secondary heat exchanger; Tripped rollout safety switch	Turn the furnace off and call a licensed technician — do not reset the rollout switch yourself

Amana furnace codes we get called for most

1 Flash — Furnace lockout due to an excessive number of ignition retries (typically 3). The control automatically attempts to reset from lockout after one hour

Typical causes include no gas to the burners (interrupted gas supply); weak, cracked, or misaligned hot-surface igniter; dirty or oxidized flame sensor (flame not proven). A few things are safe to check yourself (Confirm the gas is on and other gas appliances in the home work; Replace a clogged air filter, which can cause nuisance lockouts), but the repair is a licensed, TSBC-certified gas technician job. HeatLand diagnoses and fixes 1 Flash on Amana furnaces throughout Greater Vancouver.

2 Flashes — Pressure switch circuit is closed (stuck closed) while the induced-draft blower is not operating, i.e. the pressure switch is closed when it should be open at the start of the cycle

Typical causes include pressure switch stuck closed or shorted; induced-draft (inducer) blower not running; wiring fault shorting the pressure-switch circuit. A few things are safe to check yourself (Power-cycle the furnace once to see if the code clears; Note the code for your technician — internal switch/inducer diagnosis is not a homeowner task), but the repair is a licensed, TSBC-certified gas technician job. HeatLand diagnoses and fixes 2 Flashes on Amana furnaces throughout Greater Vancouver.

4 Flashes — Open high-limit switch (primary limit open), usually caused by the furnace overheating

Typical causes include dirty or clogged air filter restricting airflow; blocked supply or return registers/ducts; failed or slow blower motor. A few things are safe to check yourself (Replace a dirty air filter (the single most common cause); Make sure supply and return vents/registers are open and not blocked by furniture or rugs), but the repair is a licensed, TSBC-certified gas technician job. HeatLand diagnoses and fixes 4 Flashes on Amana furnaces throughout Greater Vancouver.

Is it safe to keep running a Amana furnace with a fault code?

Most Amana fault codes put the furnace into a safe lockout for a reason. You can safely check the basics — the furnace switch and breaker on, a clean air filter, the gas supply on, the thermostat set to heat and calling, and — on high-efficiency models — the condensate drain not blocked or frozen — and restart it once. If the code returns, stop and book a technician. If you ever smell gas, leave the building and call your gas utility’s emergency line or 911 first. If a carbon-monoxide alarm sounds, get everyone out and call 911. A rollout or repeated limit trip can signal a heat-exchanger or venting problem — don’t keep resetting it.

Amana furnace error code FAQs

Can I reset my Amana furnace myself?

Yes — power-cycling the reset button once is generally safe after you’ve checked the basics (the furnace switch and breaker on, a clean air filter, the gas supply on, the thermostat set to heat and calling, and — on high-efficiency models — the condensate drain not blocked or frozen). If the furnace faults again right away, stop and note the code — repeatedly resetting a furnace that keeps locking out can mask a real problem. Call a licensed, TSBC-certified gas technician to diagnose it.

What does the Amana 1 Flash code mean?

On Amana furnaces, 1 Flash commonly indicates furnace lockout due to an excessive number of ignition retries (typically 3). the control automatically attempts to reset from lockout after one hour. Confirm the exact meaning against your unit’s manual — codes can vary by model and series — and have the repair done by a licensed, TSBC-certified gas technician. HeatLand fixes this across Greater Vancouver.

Do you repair Amana furnaces you didn’t install?

Yes. HeatLand is brand-agnostic and services Amana furnaces throughout Metro Vancouver and the Fraser Valley, whether or not we installed the unit. We carry common parts and give you an honest repair-or-replace assessment.

Is a Amana furnace fault code an emergency?

No heat in cold weather is worth treating urgently. If you ever smell gas, leave the building and call your gas utility’s emergency line or 911 first. If a carbon-monoxide alarm sounds, get everyone out and call 911. A rollout or repeated limit trip can signal a heat-exchanger or venting problem — don’t keep resetting it. For priority furnace repair across Greater Vancouver, call (604) 330-3812.

How much does Amana furnace repair cost in Vancouver?

It depends on the fault. Many Amana codes point to sensors, ignition or pump parts — usually far cheaper than replacement. We give upfront pricing and a free estimate before any work.
