Frigidaire Refrigerator HE Error Code

Main control to sub-board link fault

What this error means

HE is a serial communication fault between main control and distributed modules.

How HE is detected

When HE 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 HE calls are resolved without parts: reseat every harness at main board. 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 HE 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

  • Corroded CAN connector
  • Mismatched control after repair
  • Intermittent neutral
  • Failed main UART

Step-by-step fixes

  1. 1Reseat every harness at main board
  2. 2Check for combination HD or SY codes
  3. 3Record model and serial
  4. 4Avoid mixing board revisions

When to call a technician

HE after full harness service needs main control replacement.

Affected models

  • Frigidaire FRSS2623AS
  • Frigidaire GRFS2853AF
  • Frigidaire FFHB2750TS

Prevention & maintenance

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