Maytag Oven Temperature Not Accurate — What’s Happening
A Maytag oven that is temperature not accurate means the oven heats but the actual cavity temperature does not match your setpoint. The oven may run too hot, too cold, or swing unpredictably. Maytag treats this as a calibration issue first, not an immediate parts failure, because oven temperatures can vary with age and element cycling.
If the control displays a specific fault code like F1E5, the temperature sensor circuit is out of range (open, shorted, or otherwise faulty). If there is no code, the problem may be calibration drift, a failing sensor, sensor position, wiring, power supply, or a heating component issue.
Most Likely Causes
- Incorrect calibration or control offset The most common cause is calibration drift over time, which Maytag recommends correcting through the oven’s built-in calibration function before replacing any parts.
- Failed temperature sensor or thermistor A malfunctioning sensor will report incorrect cavity temperature to the control, causing the oven to under- or overheat.
- Sensor position or installation issue If the sensor has been bumped or is not properly mounted at roughly 90° to the back wall, readings will be inaccurate and can often be fixed by repositioning.
- Loose or damaged sensor wiring or connector Corroded, loose, or overheated terminals at the sensor connector can cause intermittent or out-of-range readings.
- Heating element or relay problem Weak bake or broil elements, or a failing relay, can cause uneven or slow heating that makes temperature control unreliable.
- Electrical supply or breaker issue Inadequate line voltage, a tripped breaker, or loose power connection can reduce heating performance and affect temperature accuracy.
- Gas valve or ignitor problem (gas models) A worn or dirty ignitor, or a partially open gas valve, will cause underheating and poor temperature control on gas ovens.
How to Diagnose and Fix
- Confirm the symptom by running a bake cycle and noting whether the oven is consistently too hot, too cold, or erratic, and check the control for any stored fault codes such as F1E5.
- Recalibrate the oven using the model-specific method: enter Settings/Options/Tools, or hold the Temp down arrow for 5 seconds, or hold Bake for 5 seconds, depending on your control, then adjust the offset and save.
- Turn off power at the breaker and access the temperature sensor at the rear of the oven cavity or behind the back panel.
- Inspect the sensor connector for loose, corroded, or burned terminals and check that the sensor probe is fully seated and positioned at roughly 90° to the back wall.
- Disconnect the sensor and measure resistance at the connector with a multimeter, expecting about 1.0 to 1.2 kΩ at room temperature for most Maytag models.
- If the sensor reads open, shorted, or far out of range, replace the temperature sensor.
- Verify line power at the outlet or junction box, confirm the breaker or fuse is intact, and on gas models verify the gas shutoff valve is fully open.
- If the sensor and calibration are correct but heating is weak or uneven, inspect the bake element for continuity on electric models, or have a technician check the ignitor and gas valve on gas ovens.
Parts You Might Need
| Part | Notes |
|---|---|
| Oven temperature sensor | Amazon | Also called thermistor. Should read 1.0–1.2 kΩ at room temperature on most Maytag ranges. |
| Bake element | Amazon | Electric models only. Replace if open or visibly damaged. |
| Oven ignitor | Amazon | Gas models. A weak or dirty ignitor causes slow heating and inaccurate temperature. |

When to Call a Pro
Call a technician if recalibration does not fix the temperature problem and you are not comfortable working inside the oven or testing live electrical circuits. Gas oven work involving the ignitor, gas valve, or burner should always be handled by a qualified service provider. If the control board is suspected or the oven shows fault codes after sensor replacement, professional diagnosis is recommended. For gas line, burner, or igniter work, or if you ever smell gas, stop and call a licensed technician.
