Microwaves are the one appliance we tell people never to open. Even unplugged, the internal capacitor can hold a dangerous high-voltage charge. So these checks stay on the outside — anything internal is a call, every time.
Safe things you can check:
When to call us: Any internal repair — magnetron, diode, capacitor, control board — is a job for a pro. On low-cost countertop units we'll tell you honestly if replacement is the smarter buy.
Safe things you can check:
When to call us: No heat almost always means the magnetron or high-voltage components — call us; do not open it yourself.
