What 4d32 means

Code 4d32 on Whirlpool built-in microwaves and microwave drawers, model WMC50522AS among them, concerns the oven control and its wiring. It does not name a failed part. The practical effect is a code on the display and an oven that may not carry on with its normal functions. A one-minute power reset is the only owner action, and the code coming back afterward is what tells us the control needs a closer look.

Common causes of 4d32

  • Oven control that keeps flagging a condition it cannot clear
  • Wiring feeding the control
  • Short-lived glitch that a restart removes
✓ One safe check you can try

1. Use the breaker to cut power to the microwave for one minute. 2. Restore power at the breaker. 3. Keep watching for one minute for any return of 4d32. 4. Run a brief test to confirm the oven works.

! Why to stop there
  • If 4d32 comes back, we test the control board and trace its connections
  • We separate control problems from wiring problems before quoting
  • You approve the written price first, with a 30-day workmanship warranty on the work
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.

4d324d32 questions
Is 4d32 a serious code?

It is a control-circuit message, so treat it as something to check rather than ignore. If one breaker reset clears it for good, that is fine. If it comes back, schedule a visit and let us test the control.

Should I keep resetting the breaker if the code returns?

One reset is the manufacturer step. If the code returns, repeated resets only delay the repair and hide what the control is reporting. Leave the oven off and let us test it with the power disconnected.

Do you repair older Whirlpool built-ins?

Yes. Many are still in service around Houston, and we repair them after testing the control. We tell you plainly, with a written price, when a repair is not worth the cost.
