Smell gas? Leave the building now. Do not touch light switches, phones or appliances inside. Call your gas utility or 911 from outside. CO alarm sounding or headache, dizziness or nausea? Get everyone outside and call 911. Gas valves, burners, venting and wiring are for a licensed technician only. See our safety policy.

Codes by system

Heating

All GE GeoSpring water heater error codes

Codes marked "Reset only" or "Service" have no separate page because the manufacturer publishes no owner fix beyond a reset or a service call.

Code	Meaning	System	Owner action
FA	Compressor discharge temperature not rising. The T4 sensor (compressor outlet temperature sensor) must detect at least a 20-degree temperature rise during the first 30 minutes of run time.	Heating	Service
FB	Compressor discharge temperature not stable. The T4 sensor (compressor outlet temperature) must be greater than 120 degrees Fahrenheit after 30 minutes of run time.	Heating	Service
FC	Evaporator frosted over. The T3a sensor (evaporator inlet temperature) must be greater than 20 degrees Fahrenheit after 30 minutes of run time. The T3 sensor should measure approximately 10k ohms at 77 degrees or 57k-3k when the evaporator inlet temperature is 15-130 degrees.	Heating	Service
FD	Super heat is too low.	Heating	Owner checks
FE	Discharge temperature above the limit. The compressor discharge temperature exceeded 240 degrees Fahrenheit.	Heating	Service
F2	Tank temperature sensor failure. The control checks the T2 tank sensor temperature before the compressor starts and it must be 30-u2013170 degrees Fahrenheit. The ohm resistance should measure approximately 10k ohms at 77 degrees.	Heating	Service
F3	Compressor failure. The control energized the compressor but the current sensor does not detect any current flow.	Heating	Service
F4	Fan failure.	Venting / airflow	Service
F5	T3a sensor failure. The ohm resistance of the T3a, T3b and T5 sensors should measure approximately 10k ohms at 77 degrees.	Sensors	Service
F6	T3b sensor failure. The ohm resistance of sensors T3a, T3b and T5 must measure approximately 10k ohms at 77 degrees Fahrenheit.	Sensors	Service
F7	T4 sensor failure. The ohm resistance of T4 sensor should measure approximately 55k ohms at 77 degrees Fahrenheit.	Sensors	Service
F8	T5 sensor failure. The ohm resistance should measure approximately 10k ohms at 77 degrees Fahrenheit.	Sensors	Service
F9	Lower heating element failure. The heating element should measures 12.8-18.75 ohms of resistance.	Heating	Service
F10	Upper heating element failure. The heating element should measure 12.8-18.75 ohms of resistance.	Heating	Service
