Frigidaire Refrigerator H3 Error Code
Freezer evaporator fan not running
What this error means
H3 means the freezer evaporator fan did not report rotation.
How H3 is detected
Heating faults such as H3 appear when the Frigidaire refrigerator control energizes the bake element, broil element, gas valve, or drying heater but does not detect expected temperature rise within the monitoring window. On Frigidaire FRSS2623AS, Frigidaire GRFS2853AF, and similar variants, open heating elements, failed igniters on gas dryers and ranges, or welded heater relays on the control board produce similar symptoms.
Ice bridge blocking fan should be ruled out first. defrost ice at fan shroud with power off. On electric ovens and dryers, test element continuity when cool; on gas appliances verify the ignitor glows for at least 15 seconds before the valve opens. Repeated H3 after confirming heat at the exhaust or oven cavity indicates a sensor or board issue rather than a simple element replacement.
Common causes
- Ice bridge blocking fan
- Fan motor connector loose
- Failed fan bearing
- Door switch not closing fan circuit
Step-by-step fixes
- 1Defrost ice at fan shroud with power off
- 2Spin blade by hand when unplugged
- 3Listen for fan 30 seconds after closing door
- 4Verify door switch depresses fully
When to call a technician
Fan motor with no spin and clear blades needs 5304517154 or model fan.
Affected models
- Frigidaire FRSS2623AS
- Frigidaire GRFS2853AF
- Frigidaire FFHB2750TS
Prevention & maintenance
- Preheat the oven only as directed and avoid foil lining the bottom—blocked airflow causes heat faults related to H3.
- Record when H3 appears in the cycle and whether it clears after a 60-second power reset on your Frigidaire refrigerator—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for H3; Frigidaire uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting H3; reversed plugs on pumps and valves cause immediate repeat faults.
