There is only 1 diode in a microwave. If you can't unplug your microwave, the socket and plug may have fused together, in which case you'll need to turn of the electricity supply and try applying a little force to get them to come apart. This component is part of the high voltage circuit along with the capacitor and the magnetron. High voltage diode in a microwave keeps blowing. door open or door closed).Make absolutely sure you remember to follow the safety instructions provided at the beginning of this article. It's possible that when you put your food in the microwave, liquid of some kind ran under the turntable and you then forgot to clean it up. I have been working on a maytag o/r microwave. It basically the thermo cut-off sensor. The cooling fan might have died or lost its effectiveness. I replaced with a universal diode. Your microwave's timer will be either mechanical or electronic in design. NOTE: Before you test your diode, make sure your microwave is unplugged, and that you discharge the microwave's capacitor. This high voltage powers the magnetron to heat the food. Here are some possible causes of repeated blown fuses, from the easiest to fix at home to the hardest. I replaced the HV diode and it still made the loud buzzing sound. The magnetron sits inside the microwave's outer casing. You should not obtain any values. An object might have gotten lodged in the fan and stopped it from rotating. Next, locate and remove the high voltage diode in order to test it for continuity. To take the measurement, disconnect the magnetron's connectors and place the multimeter's probes on its terminals. Checked the circuit (I am an engineer, so no worries about high voltages), found a failed diode. Attach your amp probe to the line splitter, plug in and run microwave 10-20 seconds. Repeat the operation for each terminal. I saw 250V 20A inscribed on the old fuse, so I got a pack of these to replace it.. After replacing the fuse, the microwave powers on and I was able to set the time on the clock, use the cooktop light, etc. If the transformer is defective, the appliance will make a lot of noise and could trip the circuit or blow a fuse. If the door switches are new and the capacitor has been replaced, that really only leaves the magnetron. It does not heat. To verify the result, also check to see if there is any current leaking anywhere. To enable all features please, YAF.NET © 2003-2020, Yet Another Forum.NET. And diode went bad again. Make absolutely sure you carefully follow the safety instructions provided at the beginning of this troubleshooting guide. WARNING We recommend adopting a very cautious and safety-conscious approach if you need to take your microwave apart at any point. If not, then that most likely means your microwave does not have a dedicated circuit. In simpler terms, this means the microwave has its own circuit breaker. When the live end of the secondary HV winding is positive, the diode is forward biased, shorting the magnetron. Then locate the turntable motor, which will be underneath the appliance. Your microwave may be tripping the power due to an issue with its electricity supply.

The turntable motor enables your microwave to cook food uniformly. Before testing this component, check your multimeter is definitely set to "Ohms Ω" and make sure you've discharged the capacitor. However, you don't need to use the exact combined part - which may be very expensive or difficult to obtain. Replaced the diode, the microwave worked for about a week, then showed the same problem.
