Maytag codesMaytag range codes

Error in control circuitry; monitors relay outputs or heating function when in time-of-day mode, shuts system down to safe condition; also monitors over-temperature condition for a chosen heating function (e.g., over 550°F in bake mode).

First step from the service manual

Check oven sensor for correct ohm value or for charred connector; if sensor is OK, replace the control.

What F1 means on a Maytag range

The F1 code on a Maytag range indicates a fault detected in the control board's internal circuitry. Specifically, the board monitors relay output and heating function performance during time-of-day mode, and it also watches for over-temperature conditions during active cooking functions. On a bake cycle, for example, F1 can trigger when the oven cavity exceeds approximately 550°F. The two primary suspects are the oven temperature sensor and the electronic control board itself.

For homeowners, this code means the oven's brain detected something it considers abnormal, either the temperature climbed beyond safe limits or the control board received a signal it could not interpret correctly. The oven temperature sensor is a probe mounted inside the oven cavity that reports the temperature back to the control board. If that sensor has failed, corroded, or developed a damaged connector, the board receives bad data and responds with F1. If the sensor tests within its correct resistance range, the control board itself has failed and needs to be replaced.

Before replacing anything, a resistance check on the oven sensor with a multimeter is the correct first step. A visually charred or melted connector at the sensor is also a clear sign of where the problem originates.

Common causes of F1

  1. 01

    Failed or out-of-range oven temperature sensor

    Part replacement

    The oven sensor, also called the RTD probe, should read approximately 1,080 to 1,100 ohms at room temperature. If it reads open, shorted, or well outside this range, the control board cannot accurately monitor oven temperature and triggers F1.

  2. 02

    Charred or damaged sensor connector

    Part replacement

    Heat damage to the wiring harness connector at the oven sensor can cause intermittent or false resistance readings. Even if the sensor itself tests correctly, a burnt connector disrupts the signal and can trigger F1.

  3. 03

    Actual over-temperature condition in the oven cavity

    Part replacement

    If a relay on the control board sticks in the closed position, the bake or broil element stays energized continuously, driving the oven temperature beyond 550°F and triggering the F1 over-temperature protection. This scenario points to a failed relay on the control board.

  4. 04

    Faulty electronic control board

    Part replacement

    If the oven sensor tests within specification and the wiring and connector are intact, the control board itself has an internal fault in the relay output or monitoring circuitry. Replacing the control board is the correct resolution in this case.

Frequently asked questions about F1

What does F1 mean on a Maytag range?
F1 on a Maytag range signals a fault in the control board's circuitry, specifically in how it monitors relay output or heating function during operation. It also triggers when the oven detects an over-temperature condition, such as the bake mode exceeding approximately 550°F. The two most common sources are a failed oven temperature sensor and a faulty control board.
How do I fix the F1 error code on my Maytag range?
Start by testing the oven temperature sensor with a multimeter. At room temperature, the sensor should read around 1,080 to 1,100 ohms. Also inspect the sensor's wiring connector inside the oven for any charring or melting. If the sensor and connector are both in good condition, the electronic control board has failed and needs to be replaced. Both repairs are within reach for a confident DIYer comfortable with appliance disassembly.
Is it safe to use my Maytag range while the F1 code is showing?
No, you should not continue using the oven while F1 is active. This code can indicate that the oven temperature exceeded 550°F, which is a potential fire and food safety hazard. It can also indicate a stuck relay that keeps a heating element energized when it should be off. Disconnect power to the range and do not operate the oven until the fault is diagnosed and repaired.
How much does it cost to repair an F1 error on a Maytag range?
An oven temperature sensor typically costs between $20 and $60 for the part and is one of the easier range repairs to perform yourself. If the control board is the cause, the board itself generally runs between $150 and $350 depending on the model, and professional installation adds another $100 to $200 in labor. Diagnosing the sensor first is worthwhile since it is the cheaper and more common failure.
Will clearing the F1 code on my Maytag range fix the problem?
Clearing the code by cutting power to the range will stop the display and may allow temporary use, but it does not fix the underlying fault. If the oven sensor is failing or the control board has an internal fault, F1 will return during the next cooking cycle. Use the power reset only to confirm whether the code is persistent, then proceed with sensor testing before ordering parts.
