What 3d31 means

On Whirlpool built-in microwaves and microwave drawers, including the WMC50522AS, 3d31 refers to the meat probe. The instruction behind it is to make sure the probe is pushed all the way into its receptacle, which can sit in different places depending on the model. A probe that is not seated, or a receptacle that is not making contact, is the first thing to look at when this code shows.

Common causes of 3d31

  • Meat probe not fully pushed into its receptacle
  • Probe or receptacle contact not making connection
  • Probe circuit condition cleared by power cycle
✓ One safe check you can try

1. Check that the meat probe is firmly inserted in its receptacle. The location varies by model. 2. Turn off the circuit breaker for the microwave for one minute. 3. Turn the breaker on again. 4. Watch the oven for one minute to confirm 3d31 does not return. 5. Run the oven to verify normal operation.

! Why to stop there
  • If the code stays with the probe seated, we test the probe and its receptacle connection
  • A worn probe or receptacle can look fine and still lose contact
  • We quote in writing before work, with 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.

3d313d31 questions
Where does the meat probe plug in on my microwave?

The receptacle location varies by model. Check your owner guide, push the probe in fully, and listen or feel for it seating. Then watch whether 3d31 returns.

Do I need a breaker reset after reseating the probe?

The manufacturer steps include a one-minute breaker reset after you confirm the probe is seated. Then monitor the oven for a minute to make sure the code stays off.

Can the probe itself be replaced on an older model?

Often, yes. Older built-in microwaves are still common in Houston, and we check the probe and receptacle first. If a repair is not worth it, we say so.
