KitchenAid Over-the-Range Microwave Code E13: appliance control board

What E13 means

On KitchenAid over-the-range microwave hood combinations such as the KMHS120ESS or KMLS311HSS, E13 means there may be a problem with the appliance control board or the associated wiring. The board controls heating, the fan, the light and the display, so the microwave may not run at all or may behave erratically when this code is present.

Common causes of E13

Appliance control board internal problem
Wiring or connectors at the board loose
Power disturbance that upset the board

✓ One safe check you can try

1. Press Cancel. 2. Unplug the microwave for a minute, or turn its breaker off, then restore power. 3. Check that the display starts. 4. If E13 returns, leave the unit unplugged and call us.

Control boards are costly, so the cause should be confirmed before a part is ordered

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E13E13 questions

How serious is E13?

It involves the main control board, so it is not a nuisance message. Plan for a technician visit.

Could a power surge cause E13?

Yes, surges can upset the board. A reset may help once, but a repeat code points to damage.

Will the exhaust fan and light still work?

Sometimes, because they have their own switches. If they do not, tell us when you call so we know the extent.
