Microwave runs but food stays cold? Blown diode, magnetron failure, or door switch issues. Safe diagnosis tips.
Your microwave turns on, the light works, the turntable spins, but food stays cold. This means the microwave is not producing heat.
WARNING: Microwaves contain high-voltage capacitors that can shock even when unplugged. Do not open the casing unless you are trained.
Check the door switches. If any switch is faulty, the microwave will run but not heat for safety reasons.
A blown high-voltage diode is the most common cause. Replacement costs UGX 20,000-40,000 plus labor.
The magnetron (the component that produces microwaves) may have failed. This costs UGX 100,000-200,000 to replace.
Microwave repair in Kampala costs UGX 50,000-200,000. New microwaves from UGX 200,000. For microwaves over 3 years old, replacement is usually the better option.
