Frigidaire Dryer E01 Error Code
Door switch circuit open
What this error means
E01 means the door switch never reported closed. Frigidaire dryers block the motor until the plunger is fully depressed.
How E01 is detected
When E01 appears on a Frigidaire dryer, the control board has confirmed that water did not leave the machine within the programmed drain window. On Frigidaire FREQG5022AW, Frigidaire FFRE4120SW, 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 E01 calls are resolved without parts: close door until drum light goes out. 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 E01 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
- Worn door catch
- Broken switch lever
- Door hinge sag
- Failed door switch
Step-by-step fixes
- 1Close door until drum light goes out
- 2Inspect plunger through front gap

- 4Tighten hinge screws
When to call a technician
Door switch is a common owner-replaceable part on FREQ models.
Affected models
- Frigidaire FREQG5022AW
- Frigidaire FFRE4120SW
- Frigidaire CFLE3911AW
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use dryers to prevent E01 from lint and food debris buildup.
- Record when E01 appears in the cycle and whether it clears after a 60-second power reset on your Frigidaire dryer—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for E01; Frigidaire uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting E01; reversed plugs on pumps and valves cause immediate repeat faults.
