Code: 1c7c

Warranty: 30-day workmanship

What 1c7c means

Code 1c7c on a Whirlpool wall oven, including microwave-combo models like the WOC54EC7HS, tells us the oven control or its wiring has reported a problem. The published information does not narrow it further. In a combination unit the oven and microwave sections can look dead together, so note whether the microwave side still works before you call. Keep the display message in mind when you call.

Common causes of 1c7c

Oven control and display circuit
Wire harness between the control and the cavity
Supply voltage reaching the unit

✓ One safe check you can try

1. Shut off the breaker or breakers feeding the oven for one minute. 2. Turn them on again. 3. Look at the display for one minute and note whether 1c7c comes back. 4. Confirm the oven runs a normal bake cycle.

! Why to stop there

We cannot tell from the code whether the control or a connection is the cause.
On a combination unit we check the microwave section separately from the oven.
We give a written price first, and the work is covered by our 30-day workmanship warranty.

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.

1c7c1c7c questions

My combination oven shows 1c7c; is the microwave also affected?

It can be, since both sections run from related electronics. Test the microwave after the reset and tell us what works. That helps us choose where to start.

Can I reset the oven without the breaker?

The steps given for this code use the breaker for one minute. We do not suggest button combinations or any other reset, because the guidance does not include them.

Will you repair an older combination oven?

We stay honest about cost: a built-in with a failing control can still be worth saving, and we show you the numbers first. The price comes before the work.
