Frigidaire Refrigerator H2 Error Code
Fresh food temperature sensor fault
What this error means
H2 indicates the refrigerator compartment thermistor failed.
How H2 is detected
When H2 appears on a Frigidaire refrigerator, the control board has confirmed that water did not leave the machine within the programmed drain window. On Frigidaire FRSS2623AS, Frigidaire GRFS2853AF, and similar variants, the drain pump runs for a fixed interval—often three to seven minutes on washers and dishwashers—while a pressure switch or turbidity sensor verifies the tub or sump is empty. If water remains, the cycle stops to prevent spin with a full tub or overflow on the next fill.
Most H2 calls are resolved without parts: press sensor fully into airflow duct clip. Restricted drain paths mimic pump failure because the impeller spins against a blocked hose or filter. Document whether the pump hums audibly during the drain step; a humming pump with no water movement points to a clogged filter or kinked hose, while silence may indicate a failed pump motor or loose wiring at the harness.
After clearing blockages, run a short cycle and listen at the drain hose for steady water flow. If H2 returns on the next load with a clean filter and straight hose, measure resistance at the pump motor connector per the service manual for your model before ordering a replacement pump assembly.
Common causes
- Thermistor pulled from duct clip
- Corrosion at board connector
- Open sensor wire
- Shorted sensor from moisture
Step-by-step fixes
- 1Press sensor fully into airflow duct clip
- 2Reseat harness at main board
- 3Monitor fresh food temps 12 hours
- 4Avoid blocking sensor grille with tall items
When to call a technician
Good sensor resistance but H2 needs board or harness service.
Affected models
- Frigidaire FRSS2623AS
- Frigidaire GRFS2853AF
- Frigidaire FFHB2750TS
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use refrigerators to prevent H2 from lint and food debris buildup.
- Record when H2 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 H2; Frigidaire uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting H2; reversed plugs on pumps and valves cause immediate repeat faults.
