Maytag Oven Error Code 3d11

Code 3d11 means the control board is reading infinite ohms from the upper or single oven temperature sensor, indicating an open circuit in the sensor or its wiring. The oven cannot measure cavity temperature, so all cooking functions for that cavity are disabled until the fault is fixed. The sensor probe, wiring harness, or connector are the most likely culprits.

Start by testing the temperature sensor for continuity using a multimeter. Disconnect the sensor leads and check resistance across the sensor terminals. A working RTD sensor typically reads around 1080 to 1100 ohms at room temperature. If your reading is infinite (OL), the sensor is open and needs to be replaced. Also inspect the wiring harness and connectors between the sensor and control board for damage or loose connections before ordering a new sensor.

Unplug the oven or shut off the circuit breaker, then locate the temperature sensor probe inside the oven cavity. Disconnect the sensor connector from the wiring harness and set your multimeter to measure resistance (ohms). Touch the probes to the two sensor terminals. At room temperature a good sensor reads approximately 1080 to 1100 ohms. A reading of infinite ohms or OL confirms the sensor has an open circuit and needs to be replaced to clear 3d11.

No. The 3d11 code disables all cook functions for the affected oven cavity, so the oven will not operate until the fault is cleared. This is a protective lockout, not a warning, and the oven will not heat regardless of what settings you select. You must repair or replace the faulty sensor or wiring before the oven will function again.

A replacement Maytag oven temperature sensor typically costs between $20 and $60 for the part, and the repair is generally accessible for a confident DIYer with a multimeter and basic hand tools. If a technician does the repair, expect to add $75 to $150 in labor depending on your area. If the control board is at fault instead of the sensor, parts cost rises significantly, often $150 to $300 or more for the board alone.
