Maytag Oven Error Code 3d42

Error code 3d42 means the oven's control board has detected a short circuit in the meat probe connected to the lower oven cavity. The probe resistance has dropped below the minimum expected threshold, reading less than 0 ohms. This prevents the probe function from operating correctly and triggers the fault code to alert you to the problem.

The oven's core baking and broiling functions may still operate, but you should not use the meat probe feature while this code is active. Continuing to use a shorted probe could potentially cause further damage to the probe socket or control board input circuit. Disable all probe functions as directed and address the fault before using the probe again.

If only the meat probe needs replacement, parts typically range from around $25 to $70 depending on the specific probe model. If the internal wiring harness is damaged, repair costs can rise to the $100 to $250 range including labor. Control board replacement, the most expensive scenario, can range from $200 to $450 or more for parts and professional installation.

Many cases of 3d42 can be resolved by removing the meat probe, inspecting it for damage, and cleaning the probe socket in the lower cavity. If the probe cable is visibly damaged or the connector is burned, replacing the probe is a straightforward repair most homeowners can do. However, if the code persists without any probe inserted, the wiring harness or control board will need professional diagnosis.

A power reset by turning off the oven at the breaker for a few minutes may temporarily clear the code, but it will return as soon as the control board re-checks the probe circuit if the underlying fault still exists. The short circuit condition must be corrected, typically by removing or replacing the damaged probe, before the error will stay cleared.
