Runs but does not heat
The timer counts down but food remains cold.
Help for built-in and over-the-range microwaves with heating, turntable, door or control faults at customer locations across Jerza Pro's confirmed service area.

Microwaves contain high-voltage components that can retain dangerous energy after power is disconnected. Do not remove the cabinet. Report whether the unit runs without heating, stops when the door moves or shows signs of arcing. Also note display response, turntable motion, interior light, vent fan and the exact sound at startup because those visible functions add context without unsafe internal testing.
Specialty kitchen appliances use compact fans, controls, lighting, cooling or high-voltage components. The appliance should be identified precisely before any repair scope or part requirement is discussed.
