Microwave Runs but Does Not Heat: Safe Checks
Quick answer

If the microwave lights and spins but food stays cold, check that the door closes fully, the power level and timer are set correctly and try a cup of water for two minutes. A microwave contains a high-voltage capacitor even when unplugged, so do not open it. Failed magnetron, diode or capacitor needs a technician or replacement.
