Heat Pump error codes by brand

The most common problems behind heat pump error codes

• Communication faults — the indoor and outdoor units lose their signal (wiring, connector or board fault).
• Sensor / thermistor errors — a coil or room sensor reads out of range.
• Fan & compressor faults — a failing fan motor, capacitor or inverter/compressor.
• Refrigerant & pressure faults — low charge, a leak, or a high/low-pressure trip.
• Control-board & power faults — PCB errors, voltage problems or a tripped breaker.

Most of these are licensed HVAC technician repairs — but many are sensors or parts, usually far cheaper than replacing the heat pump.

Heat Pump error code FAQs

What do heat pump error codes mean?

A heat pump error code is the control board telling you which safety or sensor condition stopped the unit. The exact meaning depends on the brand and model, so always confirm against your unit’s manual and have the repair done by a licensed HVAC technician.

Can I clear a heat pump fault code myself?

You can safely check the basics (the power and breaker on, the indoor filter clean, the outdoor unit clear of snow, ice and debris, and the remote set to the correct mode and temperature) and restart once. If the code comes back, stop and call a licensed HVAC technician.
