Maytag Oven Not Heating — What’s Happening
A Maytag oven that won’t heat is a symptom, not a single fault. The root cause depends on whether your oven is gas or electric and whether the display shows an error code. If you see F2, the control thinks the oven is overheating and may have disabled heating due to a relay board or sensor issue. If you see F3 or F4, the oven temperature sensor is reading open or shorted, so the control can’t regulate heat. If there’s no code at all, the problem is usually a failed heating element, bad ignitor, sensor issue, or a power or gas supply problem.
Maytag’s own troubleshooting points to the ignitor on gas models, the bake element and temperature sensor on electric models, and control or relay boards when codes are present. Calibration settings or a Celsius/Fahrenheit mix-up can also prevent the oven from reaching the expected temperature.
Most Likely Causes
- Failed bake element (electric ovens) The lower bake element burns out over time and is one of the most common no-heat failures in electric ovens.
- Weak or dirty ignitor (gas ovens) The ignitor must draw enough current to open the gas valve, and a weak or fouled ignitor will prevent the oven from lighting.
- Open or shorted oven temperature sensor (RTD) A failed sensor triggers F3 or F4 codes or causes the control to misread oven temperature and stop heating.
- Defective relay board or control board The relay board can fail to send voltage to the element or gas valve, and a failed control may also trigger F2 codes.
- Tripped breaker or partial loss of power A tripped breaker or loose connection can leave the display and controls working but cut power to the heating elements.
- Gas valve closed or no gas supply If the gas shut-off valve is off or the supply is interrupted, the oven will not heat even if the ignitor glows.
- Incorrect calibration or Celsius/Fahrenheit setting The oven may be heating but not reaching the expected temperature if the display is set to the wrong units or needs recalibration.
How to Diagnose and Fix
- Check the display for error codes F2, F3, or F4 and note whether the oven is gas or electric.
- Turn off power at the circuit breaker or fuse box for one full minute, restore power, and see if the code clears or heating resumes.
- If F3 or F4 is displayed, unplug the oven, locate the oven temperature sensor (usually at the upper rear wall), disconnect it, and measure resistance across the sensor terminals with a multimeter (should read around 1,000–1,100 ohms at room temperature). Replace the sensor if the reading is open, shorted, or far out of range.
- If there is no code and you have an electric oven, inspect the bake element for visible breaks, blisters, or burn marks. With power off, test continuity across the element terminals. Replace the element if it shows no continuity.
- If you have a gas oven and no code, look at the ignitor during a preheat cycle. If it glows weakly or not at all, or if it glows brightly but the burner never lights, the ignitor is likely weak and should be replaced by a qualified technician.
- Verify that the circuit breaker or fuse is fully on and that both legs of the 240V supply are present (on electric models) or that the gas shut-off valve is fully open and gas is flowing (on gas models).
- Check the oven temperature sensor positioning (it should not touch the oven wall) and verify the control is set to the correct temperature scale (Fahrenheit vs. Celsius). Recalibrate the oven if temperatures are consistently off.
- After replacing any part, restore power, run a test bake cycle, and clear any stored fault codes through the control’s diagnostic mode if available.

When to Call a Pro
Call a technician if you are not comfortable working with 240-volt wiring or testing live circuits, if gas work is required (ignitor or valve replacement should be done by a qualified service provider), or if you’ve replaced the sensor or element and the oven still will not heat. Also call for help if F2 codes persist after a sensor replacement, since relay board or control board diagnosis requires service-level tools and schematics. For gas line, burner, or igniter work, or if you ever smell gas, stop and call a licensed technician.
