1 Prepare safe working conditions
Unplug the appliance from the outlet, close the water supply if one exists, and wait for hot parts to cool down. Prepare the manual for your exact model and a dry work surface.
⚠ Warning: Do not open any part with electrical wiring, capacitor, magnetron, heater, or refrigerant circuit. A qualified service must handle this diagnosis.
2 Determine the condition and cause
A thin layer of droplets or frost that melts occasionally can be normal. A thick sheet of ice or continuous freezing is not.
3 Perform the key checks
Check that the door closes properly, clean the seal, and don’t lean food against the back wall. Cool warm food first and don’t block ventilation.
4 Perform repair or maintenance
Defrost the appliance according to the manual without using sharp objects. Quick ice return can mean sensor, defrost heater, or seal issues.
? Tip: Take a photo of the initial state and change only one thing at a time. That way you’ll find out more easily what actually solved the problem.
5 Test the result
Put back all accessible parts and run a brief supervised test. If you notice leaks, sparks, burning smell, or shield ejection, unplug the appliance and call service.
