Von Hotpoint microwave model HMG-202DB with “no heating problem” now repaired.

I received this microwave from my neighbor who wanted it checked by a technician.

The owner told me that there was a loud bang and since that time they set it aside (store) and were planning to buy another one since they considered the issue as beyond repair.

I took it with me to my shop and once I applied the power I noted it was powering on well, I placed a glass full of water and hit express button and after 30 seconds I checked the water and found it was still cold.

I then decided to open up the machine and do some troubleshooting.

I begin testing the H.V fuse and found its okay, next I checked the H.V diode and found it dead short.

Next I checked H.V capacitor with my multicomponent tester and found it okay as you can see the results below.

I replaced the HV diode which was found faulty and tested again with a glass of water and after 30 seconds, I found the water was a little warm.

I decided to check the H.V diode again and found it once again shorted.

Before replacing the diode again, I decided to replace the magnetron directly.

I replaced the two components and after testing again with a glass of water, I found the microwave was now working like new.

Thank you guys

See you in the next class

  1. Great article sir,repair made easy.

  2. Was the magnetron an easy part to source for this model of microwave? Was it quite a generic type, hence easy to source? I always imagined that they were quite specific to each model?
