What 1c2c means

Code 1c2c shows up on Whirlpool built-in microwaves and microwave drawers, including model WMC50522AS. It points to the user interface, which means the keypad or touch panel, or the wiring that links it to the rest of the oven. The code names a circuit rather than a failed part, so what you see is the code on the display and an oven that may not respond to the panel normally until the condition is cleared.

Common causes of 1c2c

  • Keypad or touch panel circuit reporting a problem
  • Wiring between the panel and the control
  • Temporary glitch that a power cycle clears
✓ One safe check you can try

1. Turn off the circuit breaker for the microwave and leave it off for one minute. 2. Turn the breaker back on. 3. Watch the display for one minute to see whether 1c2c comes back. 4. Try a short, simple cooking function to confirm the oven works normally. 5. Do not pry at the control panel yourself.

! Why to stop there
  • If 1c2c returns after the power cycle, we test the panel, its connector and the wiring behind it
  • We tell you what we found and the price in writing before we replace anything
  • Repairs carry a 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.

1c2c1c2c questions
Why does my microwave show 1c2c and ignore the buttons?

The code points to the keypad circuit or its wiring. Cutting the breaker for one minute clears a temporary glitch. If the buttons stay dead afterward, the panel or its connection needs testing.

Is it safe to flip the breaker to clear 1c2c?

Yes. Turn the breaker off for one minute and back on, then watch the oven for a minute. That is the only reset we ask owners to try. Anything inside the cabinet stays for us.

Can an older built-in microwave with this code be repaired?

Usually, yes. Older built-in units are still in many Houston kitchens. If the repair is not worth it compared with the unit, we say so plainly before any work.
