Maytag Range Error Code F1-4

F1-4 means the control board detected that the lower oven temperature exceeded 950°F while the door lock was engaged. This most commonly occurs during or after a self-clean cycle. The fault is designed to shut down the oven and prevent damage from extreme heat. The lower oven temperature sensor (RTD probe) is the first component to check.

No. F1-4 indicates either a genuine overtemperature condition or a sensor failure that is preventing accurate temperature monitoring of the lower oven. Using the oven for cooking or running another self-clean cycle before diagnosing and resolving the fault risks element damage, further control board damage, or in the case of an actual thermal runaway, a fire hazard. The oven should remain off until the sensor and wiring are inspected.

Yes, this is one of the most common scenarios for F1-4. Self-clean cycles push oven temperatures to 850°F to 900°F, and a sensor that is already degraded or a heating element stuck in the on position can push temperatures past the 950°F threshold before the cycle ends. If the code appeared at the end of or shortly after a self-clean cycle, inspect the lower oven temperature sensor first, then examine the bake and broil elements for visible damage or signs of arcing.

Start by letting the oven cool completely and allowing the door to unlock on its own. Once cooled, disconnect power for 60 seconds to clear the fault. If F1-4 returns, test the lower oven temperature sensor with a multimeter. At room temperature, a functioning RTD sensor typically reads approximately 1080 ohms. A reading significantly outside that range confirms a bad sensor. Replacing the sensor is a DIY-friendly repair on most Maytag ranges and typically requires removing the back panel inside the oven cavity.

If the lower oven temperature sensor is the cause, the part typically costs $20 to $60 depending on the model, and replacing it yourself is a low-difficulty repair with basic tools. If a professional technician does the work, expect a service call fee plus labor, bringing the total to $150 to $300 in most markets. If the control board is at fault, the board itself can cost $100 to $300 and professional installation is recommended for that component.
