Oven does not heat at all in any mode; fan and light may work but food remains cold.

Safety first: Disconnect power before removing panels or testing components.

Step-by-step checks:

• Verify that the clock is set and that no automatic end-time is programmed; many Teka ovens will not heat if the timer is not correctly set.
• Test each heating element (upper, lower, circular) for continuity with a multimeter. Replace any open elements.
• Check the safety thermostat (thermal cut-out) for continuity and reset or replace as needed (see E14).
• Inspect the wiring harness from the elements to the control board for burned connectors or broken wires.
• If all elements and thermostats are good, the main control board may not be supplying power to the elements and will likely need replacement.
