Step-by-Step Repair

  1. Step 1 of 6
    1

    Check the settings

    Double-check that the temperature and mode are set correctly. It sounds obvious, but incorrect settings are a surprisingly common cause of "not heating" complaints.

  2. Step 2 of 6
    2

    Inspect the vents and airflow

    Make sure all vents, filters, and airways are clean and unobstructed. Restricted airflow causes overheating, which triggers safety cutoffs that prevent heating.

  3. Step 3 of 6

    Check for a thermal fuse or safety cutoff

    Many heating devices have a thermal fuse — a one-time safety device that blows when the unit overheats. If blown, it must be replaced ($5-$15). It's usually a small white or silver component near the heating element.

  4. Step 4 of 6

    Inspect the heating element

    If you can safely access the heating element, look for visible damage — broken coils, scorch marks, or separation. A broken element needs replacement.

  5. Step 5 of 6

    Test with a multimeter (optional)

    If you have a multimeter, test the heating element for continuity. No continuity means the element is broken and needs replacement. Also test the thermal fuse.

    Clean and reassemble

    After checking everything, clean all accessible parts, reassemble, and test. Run a short cycle to see if heating has been restored.

If That Didn't Work

  • The bake or broil element may be visibly damaged — look for breaks or blistering.
  • The temperature sensor (thermistor) may need recalibration or replacement.
  • The oven control board may have a fault.

When to Call a Professional

If replacing the heating element or sensor doesn't work, the control board may need replacement ($100-$250). For gas ovens, if you smell gas or suspect a gas valve issue, call a professional immediately.
