KitchenAid Built-In Microwave Code 3d31: meat probe not seated

What 3d31 means

On KitchenAid built-in microwaves and oven combinations in the KMBP100ESS and KOCE500ESS family, 3d31 is tied to the meat probe. The first thing to verify is that the probe is pushed firmly into its receptacle, whose location varies by model. After that, a power reset is the next step. The display shows the code and probe cooking will not run.

Common causes of 3d31

Probe plug not fully pushed into the receptacle
Dirt or food residue inside the receptacle
A bent or worn probe that no longer makes contact
A momentary control error cleared only by a power reset

✓ One safe check you can try

1. Press Cancel. 2. Unplug the probe, wipe the metal tip and plug with a dry cloth, and check that nothing is bent. 3. Push the probe in until it seats fully. 4. If the code stays, switch the breaker off for one minute and back on. 5. Watch the display for a minute. If 3d31 reappears with the probe out, call us.

! Why to stop there

Most cases end at the probe plug, so a visit is wasted if the probe is simply loose
When a reset does not help, the receptacle wiring or control must be tested properly

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

What does 3d31 want me to check first?

Make sure the meat probe is fully inserted in its receptacle. The receptacle sits in different places on different models, so look along the cavity wall near the front opening.

Do I need the probe to bake or microwave?

No. Take the probe out and use time-based cooking. If the code still appears with the probe removed, the receptacle or control needs attention, not the probe.

Will resetting the power erase 3d31 for good?

It clears a one-off glitch. Watch the display for about a minute afterward. A code that returns means a persistent contact or control problem, and a technician should test it.
