Microwave runs but does not heat food; turntable, light, and fan operate normally, no error code displayed.
Safety Warning
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
How to Fix / Troubleshooting
Safety first: Unplug the microwave. The high-voltage section contains lethal voltages even after unplugging due to stored charge in the capacitor. Do not attempt internal HV repairs unless you are trained.
- 1. Confirm no heat: Place a cup of water inside and run on full power for 1–2 minutes. If the water remains cold, heating is not occurring.
- 2. Check basic operation: Ensure the timer counts down, the interior light is on, and the turntable rotates. If these work, the issue is likely in the high-voltage or magnetron circuit.
- 3. External checks only for non-professionals: Verify the door closes properly and that no error codes appear. Beyond this, internal diagnosis should be left to a technician.
- 4. Professional diagnosis: A technician will safely discharge the capacitor, then test the magnetron, HV diode, capacitor, and transformer, replacing any failed Beko-specified components.
Recommendation: Due to the risks involved, contact an authorized Beko service center for no-heat faults.
