Whirlpool Range Error Code F3E2

F3E2 means the Maxwell or MRC control board has detected that the warming drawer temperature sensor circuit is either open or shorted. The board expects to see a specific resistance range from the sensor at all times. When the reading falls outside that range, the board sets F3E2 and disables the warming drawer. The main oven burners are not affected by this code.

Yes, the main oven and surface burners remain operational when F3E2 is active. The fault is isolated to the warming drawer sensor circuit, so only the warming drawer will be disabled. You can continue cooking normally, but the warming drawer will not function until the sensor or wiring issue is resolved.

Disconnect power to the range, then locate and unplug the warming drawer sensor connector. Use a multimeter set to ohms and measure resistance across the two sensor terminals. A functioning sensor typically reads within a manufacturer-specified resistance range at room temperature, often between 1000 and 1100 ohms for a standard NTC thermistor sensor, though you should verify the exact spec in your model's service manual. An open reading of infinite ohms or a short reading near zero ohms confirms the sensor has failed and needs replacement.

Start by pressing CANCEL, CANCEL, then START to enter Diagnostics Mode and check the warming drawer sensor temperature readout. If the reading is near room temperature and seems accurate, the sensor circuit may have had a temporary fault. If the readout is missing, erratic, or shows an extreme value, the warming drawer sensor is the most likely failed part and should be replaced. After replacing the sensor, clear the code and recheck in Diagnostics Mode to confirm the repair.

A replacement warming drawer temperature sensor for a Whirlpool range typically costs between $20 and $60 for the part depending on the model. If you are comfortable using a multimeter and accessing the warming drawer cavity, this is a beginner-to-intermediate DIY repair. Professional repair service will add $100 to $200 in labor. If the control board turns out to be the faulty component, board prices range from $150 to $350, making professional diagnosis worthwhile before committing to that repair.
