GE Refrigerator HE Error Code
Main control communication fault
What this error means
HE is serial communication failure between main control and modules.
How HE is detected
When HE appears on a GE refrigerator, the control board has confirmed that water did not leave the machine within the programmed drain window. On GE GNE27JYMFS, GE PVD28BYNFS, 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 all harnesses. 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
- Board mismatch
- Bad neutral
- Failed UART
Step-by-step fixes

- 4Avoid mixing revs
When to call a technician
HE after harness needs main control.
Affected models
- GE GNE27JYMFS
- GE PVD28BYNFS
- GE GTS22KYNRFS
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 GE refrigerator—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for HE; GE 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.
