Tefal Insufficient Heating / Heat Loss

Cooking times are much longer than expected; food is undercooked even after full cycle.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Partially failed heating element, Fan running too slowly, Door or lid seal leaking hot air, Temperature sensor misreading high

Safety first: Unplug before internal checks.

Check loading: Do not overload the basket; follow Tefal capacity guidelines.
Verify temperature: Use an oven thermometer to confirm actual temperature.
Inspect seals: On lid-type models, check the silicone or rubber seal for damage or gaps.
Check fan speed: Listen for weak airflow; if low, the fan motor may be failing and should be replaced.
