When a microwave operates while food stays cold it becomes very difficult to deal with. There are multiple usual issues which could be responsible for this malfunction. The knowledge of these causes will let you determine if you need professional help for your appliance.
- Faulty Magnetron
The microwave function depends on the magnetron for making microwaves needed to heat food. The microwave will activate its power but fail to generate thermal energy when the magnetron component burns out. Professional help from Appliance Repair San Diego should be sought to replace the magnetron since it requires technical knowledge.
- Blown High-Voltage Diode
The power flowing to the magnetron is managed through the high-voltage diode. The microwave fails to create heating effects because a faulty diode is present. For safety reasons you should use a multimeter to inspect these high-voltage parts but it remains dangerous to handle them. Reporting suspected diode problems to an expert represents the best course of action.
- Defective Door Switch
Microwaves contain safety features which stop microwave operation whenever the door remains open. Failure in any switch can result in improper heating of the microwave. Check the door position while monitoring its mechanical operation during closures. Customers should ask a technician to replace faulty switches.
- Malfunctioning Capacitor
The high voltage circuit receives its power storage from the capacitor component. The magnetron will not access sufficient power when the capacitor stops operating correctly. Professional help should be obtained when replacing a capacitor because the work requires handling high-voltage components.
- Control Board Issues
The control board distributes power which enables different functioning sections of the microwave. Problems with the board will prevent heating from happening. The replacement of the control board should be considered as the final troubleshooting step if all other components function normally without fixing the problem.
A non-heating microwave can receive professional repair rather than going through the replacement process. Identifying each component is crucial for understanding the issue while safe handling of electrical components demands special attention.
