Whirlpool Microwave E13 Error Code: What It Means & What to Check
If your Whirlpool microwave is showing E13, Whirlpool’s guidance for many over-the-range microwave models says the oven did not preheat correctly. In plain English: during a preheat-related function, the unit did not reach the expected temperature in time. A one-time glitch may clear with a reset, but repeated E13 points to a control/wiring/sensing issue.
Q: What does E13 mean on a Whirlpool microwave?
A: On Whirlpool over-the-range microwaves, E13 means the oven did not preheat correctly. Whirlpool says there may be a problem with the appliance control board or the associated wiring. Start with Whirlpool’s 1-minute breaker reset and watch for the code to return.
What You May Notice
- E13 appears during or after a preheat-related cooking mode
- The microwave/oven function stops and won’t continue normally
- The unit seems to start but faults out again on the next attempt
- The code clears after reset, then returns later
Safety First
- Do not remove covers or internal panels. Microwaves contain high-voltage components that can remain dangerous even when unplugged.
- Use the circuit breaker for reset rather than trying to disassemble anything.
- If you notice burning smell, smoke, or repeated tripping breakers, stop using the unit and schedule service.
Quick Checks You Can Do Now
- Reset power at the breaker for 1 minute: Whirlpool specifically recommends turning the breaker(s) off for one minute, then back on.
- Monitor for 1 minute after restoring power: Whirlpool says to watch the display and verify the code does not reappear immediately.
- Retry operation: Verify microwave operation after the reset. If the code returns during a preheat/convection-related mode, note that pattern for service.
- Check airflow/venting around the unit (homeowner-safe visual check): Make sure exterior vents/grease filters (if applicable) aren’t heavily blocked with grease buildup that could trap heat.
- Watch for repeat occurrence: A one-time fault can be a glitch; repeated E13 usually means a real component or wiring issue.
Tip: If E13 only appears during convection/preheat-style cooking and not basic microwave reheating, that’s a strong clue for a preheat/temperature-control path issue.
Common Causes (and Likely Parts)
Whirlpool’s consumer guidance for E13 highlights a preheat failure and points primarily to the control board or associated wiring. In field diagnosis, temperature-sensing circuits may also be evaluated depending on the model and symptom pattern.
- Appliance control board issue (Whirlpool-listed possibility)
- Associated wiring / harness issue (Whirlpool-listed possibility)
- Temperature sensing circuit issue (model-dependent, based on repeated preheat failure pattern)
Parts that may be involved (model-dependent)
- Main appliance control board
- Wiring harness / connectors related to preheat sensing/control
- Temperature sensor / thermal sensing circuit components
When to Call Beacon
If E13 returns after Whirlpool’s breaker reset—or if the microwave repeatedly fails during preheat/convection functions— it’s time for diagnosis. Beacon’s friendly technicians in yellow can determine whether the fault is in the control board, wiring, or a temperature-sensing circuit and help you avoid repeat shutdowns.

FAQ: Whirlpool Microwave E13
What is Whirlpool’s first fix for E13?
Whirlpool’s Product Help says to turn the circuit breaker(s) off for one minute, then turn them back on and monitor the unit for one minute.
Does E13 mean the microwave did not preheat correctly?
Yes. Whirlpool’s E13 page for over-the-range microwaves says the oven did not pre-heat correctly.
Does E13 always mean the control board is bad?
Not always. Whirlpool says there may be a problem with the appliance control board or associated wiring. Repeated E13 typically requires diagnosis to confirm the exact cause.
Can I keep using the microwave if E13 appears once?
After a proper breaker reset, you can test operation. If E13 returns—especially during preheat/convection use—stop repeated attempts and schedule service.
Is it safe to open the microwave and check wiring myself?
No. Microwaves contain high-voltage components and are not a safe DIY appliance for internal electrical diagnosis unless you’re qualified.
When should I call Beacon?
If E13 returns after Whirlpool’s breaker reset or keeps happening during preheat/convection operation, schedule service so our friendly technicians in yellow can diagnose it safely.
