Maytag Range Error Code F1-L

F1-L means the control board has detected that both oven cavities are reporting the same temperature for an unusually long period. Each oven has its own temperature sensor, and when both read identically over time, the control board flags it as an error. This usually points to a faulty sensor, a wiring issue, or a short in the sensor circuit.

Using the range with an active F1-L code is not recommended for cooking that requires precise temperatures, because the control board may not be accurately reading or regulating the oven heat. The surface burners on a gas or electric range are typically unaffected, but the oven itself should be considered unreliable until the sensor issue is resolved. Continuing to use the oven could produce overcooked or undercooked food and may mask a worsening wiring problem.

Disconnect power to the range before starting. Locate the oven temperature sensor at the back of the oven cavity, typically a thin metal probe attached with two screws. Disconnect the sensor's wiring harness and use a multimeter set to resistance (ohms) to measure across the two sensor terminals. At room temperature (around 70 degrees Fahrenheit), a functioning sensor should read close to 1080 ohms. Readings that are much higher, much lower, or read the same as the other sensor strongly suggest a failed probe that needs replacement.

Start by testing each oven temperature sensor with a multimeter. Disconnect the sensor and measure its resistance at room temperature. A good sensor reads approximately 1080 ohms. If either sensor reads significantly outside that range or reads the same fixed value regardless of temperature, replace it. If both sensors test good, inspect the wiring harness for pinched wires, melted connectors, or shorts between the two sensor circuits.

An oven temperature sensor (RTD probe) for a Maytag range typically costs between $20 and $60 for the part, making it one of the more affordable repairs if you are comfortable doing it yourself. The sensor plugs into a connector inside the oven cavity and is usually secured by one or two screws. If the problem is the control board, parts can range from $100 to $250 or more, and professional labor adds $75 to $150 per hour depending on your area.
