Bryant Furnace Error Code 31 stands for “F1 H2 Sensor.”

This error code is displayed when the sensor in the furnace’s venturi tube is defective. The sensor detects the presence of oxygen and transmits this information to a circuit board that regulates the fuel flow. When it malfunctions, the system will experience lean combustion, which may lead to poor or no heat. It also causes high gas consumption and increased emissions.

Bryant Furnace Error Code 31 usually indicates a problem with one of two sensors: the H2 sensor (sensing oxygen) or F1 sensor (sensing fuel). The system must be inspected with an infrared camera before replacing either sensor.
