SE on a Whirlpool over-the-range microwave points to a keypad (user interface) fault, while F2H1 points to the vent fan and light switch assembly — both per Whirlpool’s own documentation. Several other codes are not faults at all: DOOR or OPEN/CLOSE DOOR just means the door sat closed for 5 minutes without a cycle starting, a safety feature to prevent unintended startup.
The documented code list
| Code / message | What Whirlpool’s official documentation says it means |
|---|---|
| SE | A problem with the Keypad (User Interface) or the associated wiring |
| F2H1 | A problem with the Vent Fan and Light Switch (lower left front side panel) or the associated wiring |
| FCE1 | Could not connect to the router — connection timeout, poor signal, a failed router, or Wi-Fi module problems |
| E62 | The Oven Sensor circuit reported a shorted condition — possibly the sensor, control board, or wiring |
| F1E4 | The oven could not execute the function due to a problem with the control board or associated wiring |
| DOOR or OPEN/CLOSE DOOR | The door has been closed 5+ minutes without a cycle starting — not a fault |
| Flashing 0:00 or PF in display | A power failure occurred |
| LOC, “L”, or padlock icon | Control lock is active |
SE: Keypad fault
- Power the unit down at the breaker for 1 minute
Whirlpool’s documented first step for this code.
- Power it back up
Restore the breaker.
- Monitor for 1 minute
Confirm the code does not return before assuming it is resolved.
- If it returns, the keypad or wiring needs service
This is a control-panel-level fault rather than something further troubleshooting at home will resolve.
F2H1: Vent fan and light switch
This points specifically to the vent fan and light switch assembly, located on the lower left front side panel on most over-the-range models, or the wiring connecting to it. The same breaker reset procedure applies as the first troubleshooting step before assuming the switch itself has failed.
FCE1: WiFi connectivity failure
This code is specific to connected/smart microwave models and covers several possible causes on the network side: a connection timeout, weak signal strength, a router that has failed, or a fault with the microwave’s own WiFi module. Check the router and signal strength at the microwave’s location before assuming the appliance itself has a hardware fault.
E62 / F1E4: Sensor and control board faults
E62 specifically means the oven sensor circuit reported a short, while F1E4 is a more general control-board-level failure to execute a function. Both point to internal electronics rather than something a power cycle reliably clears, though Whirlpool’s documented first step for most codes is still the same breaker reset before assuming a part needs replacing.
Codes that are not actually faults
DOOR or OPEN/CLOSE DOOR, the flashing clock/PF display, and LOC are all normal operational states rather than hardware faults. DOOR simply means the safety timeout kicked in after 5 minutes of the door being closed with no cycle started — open and close the door again, then start the cycle. LOC means the control lock feature is active; check your manual for the unlock combination.
When to call for service
Whirlpool’s own documented process for nearly every fault code here is the same: reset power at the breaker for 1 minute, restore it, and monitor for 1 minute. If the code returns after that, it points to the specific component named in the code’s description, and Whirlpool’s guidance is to schedule service rather than continue troubleshooting at home.
