When this happens, a lot of the time, it is because the the old bulb burnt up violently or it was unscrewed with the power still on to the unit and if the wires on the bottom of the bulb were twisted together, it probably blew a trace off of the back of the circuit board that supplies power to te bulbs. So either need to find someone to repair the circuit board or buy a new one if you can put it in, if not, need to call a servicer to replace it. But caution, thay are not cheap!!! Always unplug you microwave BEFORE replacing the bulbs!!!!!

Most likely causes are a blown fuse in HV area of microwave or an open thermal protector or thermal fuse.
Less likely causes are failure of various parts in the HV area.

Due to the lethal dangers inherent in microwaves, servicing of these parts is likely best left to a professional. That said, if you are technically versed I can point you in the direction of some good resources for troubleshooting and repair.

1. the motor to rotate the glass table in the micro wave may have stop working or the switch to the motor is defective.

Check the AC fuse in side the oven. If the fuse is ok chek the low voltage transformer . If the primary winding is open replace the transformer.

The magnetron, which is the device which creates the microwaves might have got damaged. If so, it should be replaced. Magnetron is the costliest part in a Microwave oven, check the price before before servicing it.

I hope this will solve your issue.

Good Luck.

If my solution proves useful please accept it.

Hi,It is most likely the magnetron and diode that has to be replaced. This job should be done by a tech, High voltage. Magnetron's normally have a five year warranty, check your owners manual.
