Read about some of the most common microwave problems and faults in our handy guide. Here, we're going to walk you through some potential problems to help you identify the possible cause of your faulty microwave.
Below is a list of the most common microwave issues that can occur to help you identify what may be wrong.
Microwave won't heat
If your microwave is having trouble heating anything, the most likely reason is an issue with the magnetron, which produces the microwave frequency to cook your food. A broken magnetron can't be repaired and will need to be replaced. Other possible issues include faulty diodes, a defective door switch, or transformer failure.
Microwave plate won't spin
There is a rotating motor that rotates the microwave plate, so the most likely issue is a worn-out motor — fortunately, this can be easily replaced. However, if the motor is not defective, there's likely a fault with the main control board.
Microwave is sparking
A sparking microwave is common and doesn't necessarily indicate a serious problem. Switch off the microwave immediately and inspect it to try and find the cause. Possible things to look out for are a damaged wave guide cover, worn out diode, damaged rack support or worn out paint from the inside walls.
We also offer basic guides to help you identify faults with other common kitchen appliances, including gas ovens, fridges, and electric hobs.
