Initial test indicated the machine was totally dead, I opened it and tested the power supply fuse and found it okay.

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.

Daewoo microwave oven model KOC-9Q5T came in dead now repaired.

 I got a direct message on my Facebook account from a client who wanted her microwave checked by a technician.

 

I gave her my pin location and within an hour she was at my shop via uber.

First I wanted to confirm what the customer said was the symptoms of making noise while warming food but realized the machine was totally dead.

I opened the oven and went straight to the main fuse and found it there but next to it was a huge jumper wire which was also open.
