Frigidaire Refrigerator H5 Error Code

Defrost heater circuit fault

What this error means

H5 indicates an open defrost heater or defrost circuit failure.

How H5 is detected

When H5 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 H5 calls are resolved without parts: remove freezer back panel when unplugged. 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 H5 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

  • Open defrost heater
  • Blown defrost thermal fuse
  • Loose heater connector
  • Clogged drain causing ice overload

Step-by-step fixes

  1. 1Remove freezer back panel when unplugged
  2. 2Test heater continuity
  3. 3Check defrost fuse in series
  4. 4Clear drain tube while panel is off

When to call a technician

Open heater or fuse needs part replacement and forced defrost test.

Affected models

  • Frigidaire FRSS2623AS
  • Frigidaire GRFS2853AF
  • Frigidaire FFHB2750TS

Prevention & maintenance

  • Clean drain filters and hose terminations monthly on high-use refrigerators to prevent H5 from lint and food debris buildup.
  • Record when H5 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 H5; Frigidaire uses multiple revisions with different harness lengths and board firmware.
  • Photograph wiring connector orientation before disconnecting any component while troubleshooting H5; reversed plugs on pumps and valves cause immediate repeat faults.
