KitchenAid Over-the-Range Microwave Code E63: third sensor check

What E63 means

KitchenAid over-the-range microwave hood combinations like the KMHS120ESS and KMLS311HSS can show E63 when there may be a problem with a sensor, the appliance control board, or the associated wiring. It completes the E61 to E63 trio. The display holds the code, and cooking, especially sensor cooking, may be blocked until the cause is found.

Common causes of E63

Sensor out of range
Board input reading errors
Loose sensor harness

✓ One safe check you can try

1. Press Cancel and open the door for a few minutes. 2. Wipe away moisture inside. 3. Take power off for a minute, then put it back. 4. Run a short test with a cup of water. 5. If E63 shows again, call us.

! Why to stop there

The trio of codes share wording, so measurements settle the repair
Opening the cabinet around the microwave needs the right tools
You see the written price first, and the work is warranted for 30 days

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.

E63E63 questions

Do E61, E62 and E63 need three different repairs?

They may or may not. Often the same sensor circuit or board is behind all three, but only testing confirms.

What is a sensor harness?

It is the bundle of wires connecting the sensors to the control board. A loose plug there can cause these codes.

Can steam from cooking confuse the sensor?

A heavy steam load can interfere briefly. A code that stays after the cavity dries is a real problem.
