How to Fix / Troubleshooting

Safety first: Unplug and cool the unit before internal checks.

Performance checks:

Use an oven thermometer placed in the basket to compare actual temperature to the set temperature.
Allow the unit to preheat fully before measuring.

Internal checks:

Inspect the door gasket or seal for gaps, tears, or deformation that could leak heat.
Test the cavity temperature sensor resistance at room temperature and compare to specifications if available.
Visually inspect the heating element for hot spots or partial glow, indicating uneven heating.

Corrective action:

Replace a worn or damaged door gasket/seal to improve heat retention.
Replace a faulty cavity temperature sensor if readings are out of range.
If the element is weak or partially open, replace the heating element assembly.
