A replacement for hv diode inverter microwave ux-f5b

Hi i have a inverter microwave (sharp r-380i) that is not hot but everything, light turntable works like normal replace the magnetron doesn't help. i found out the 2 hv diode in inverter board get shorted, i replaced both with cl01-12 but when run microwave, one diode got shorted again, make noise, can I buy cl04-12 for replacement, will it work? Or can i use hvr-1x instead? Or is there anything have to check more?

Model P100N30AP-F4. Turns on, turntable rotates, nothing gets hot. What's wrong?

I'm thinking magnetron failure
get a quote to fix or junk it as microwave ovens are cheaper to replace than repair

Can a microwave be repaired?

Yes it is repairable, but if you do not have any experience in the repair of microwave ovens do not engage in their repairs because it is one of the most dangerous household appliances and the consequences can be disastrous. If light and turntable works than low voltage circuit (220V or 110V) works well. In this case the problem is in a high voltage (HV) circuit which is made up of the magnetron, HV diode (rectifier), HV capacitor and HV fuse or protect diode. Failure is in any of these components in "HV circuit" or in the main board. If light and turntable does not work than fault could be in power supply elements like: power supply cord, transformer, power board, fuse (glass or ceramic, ussualy 8A, 10A or 12A) on power board.

My 5 yr old Whirlpool microwave stopped heating food. All other lights, displays, fan and turntable work. What could be the trouble?

If you do not have any experience in the repair of microwave ovens do not engage in their repairs because it is one of the most dangerous household appliances and the consequences can be disastrous. According to your description, low voltage circuit (220V or 110V) works well (light, turntable...). Obviously the problem is in a high voltage (HV) circuit which is made up of the magnetron, HV diode (rectifier), HV capacitor and HV fuse or protect diode. Failure is in any of these components in "HV circuit" or in the main board.

Whirlpool microwave keeps opening high voltage diode

If you do not have any experience in the repair of microwave ovens do not engage in their repairs because it is one of the most dangerous household appliances and the consequences can be disastrous. According to your description, low voltage circuit (220V or 110V) works well (light, turntable...). Obviously the problem is in a high voltage (HV) circuit which is made up of the magnetron, HV diode (rectifier), HV capacitor and HV fuse or protect diode. Failure is in any of these components in "HV circuit" or sometimes in interlock switch assembly or PC Board.

First, you must be sure which diode is blowed, reactifier or protect diode.

To check magnetron following this procedure:

Discconect the mains supply.
Check that the capacitor is discharged (by resistor 100 ohm / 10W or more).
Discconect the magnetron.
Measure the resistence between the disconnected terminals (should be app. 0.5 ohm).
Measure the resistance between the supply terminals (both) and earth. The resistance should be infinite.

Why does Panasonic nn-sn651 usually work; but sometimes, turntable won't start ?

This is an inverter model so there is no diode or hv capacitor.
You must adt. the door latch switch assembly to make sure that the door hooks make contact with the switches. Common problem is that the assembly is bent and must be perpendicular to the door.If it is bent the switch will not make contact with the door hooks.
Place a dab of lithium grease on the tip of the door hooks to ease closing the door. This is the cause of the bent switch assembly!

Electrolux combi integral microwave EMS26414W does not microwave/defrost.The display/turntable/light/grill does work

Failure should be found in the high voltage section of microwave oven.
Magnetron, HV capacitor, HV diode or HV fuse, tranformer HV secondary coil

AEG MCD2664E-m - plate not turning

There is no separate fuse only for turntable motor. Usually there is two fuse, one in High Voltage section (instead fuse could be HV protect diode) and another one for 220 V (light, turntable motor, fun motor, display....). If light work normally then is turtable motor faulty.

Panasonic Microwave NN-A770S getting hot on right side externally

If you described this to Panasonic very carefully, and they said it's normal, then I would say keep using it until such time that you get other symptoms. The inverter has some parts mounted on a large chunk of aluminum called a heat sink. It draws the heat out of the parts and the heat radiates and/or convects away. This keeps the circuit parts from overheating. As long as you have good air flow through the vents, it sounds okay.
