Maytag Oven Error Code 3d31

Code 3d31 means the oven's control board has detected an open circuit in the meat probe circuit for the single cavity or upper oven. This fault only activates when a probe cook cycle is programmed and persists for at least 10 seconds. When the fault is set, the control board disables both the bake element and the convection element. The most likely cause is a damaged probe or a poor connection at the probe jack.

The oven disables the heating elements when this code is active during a probe cook cycle, so normal baking or broiling without a probe should not be affected. However, you should not attempt to use the probe cook function until the fault is resolved, as the oven cannot accurately monitor food temperature in that mode. Discontinue probe cooking until the probe or its circuit is repaired.

If only the meat probe needs replacement, costs typically range from $20 to $60 for the part, plus any labor if you hire a technician. Probe jack replacement parts generally fall in the $30 to $80 range. If the control board is at fault, that repair is significantly more expensive, often ranging from $150 to $400 or more depending on the model and labor rates in your area.

In many cases, yes. Start by removing the meat probe from the oven jack, cleaning the jack contacts, and firmly reinserting the probe to ensure a solid connection. If the code returns, test the probe for continuity with a multimeter. A probe that shows no continuity needs to be replaced, which is a straightforward part swap that most DIYers can handle.

A reset may temporarily clear the code, but it will return as soon as a probe cook cycle is programmed again and the open circuit condition is still present. The 10-second debounce means the code will reappear quickly if the underlying problem is not fixed. A reset is useful for confirming the fault is active, but it does not address the root cause.
