HMC80152UC/07 Bosch Wall Oven - Instructions

Replaced the wave cover. Unscrewed existing cover that is at the top inside the microwave. Screwed in the new cover.
Took about 30 seconds to do. Bosch service wanted over $100 for a service call plus parts and labor. Did it myself in seconds for under $10.

Thermal switch on top of Magnetron was defective, spade contacts were burned and loose. New switch $6 +shipping. Removed top cover held on with several Philips head screws. Plugged unit in and gave it 30 seconds to test the fan was working, it was. Put 500ml water in cavity, ran it for 60 seconds, which after fiddling with wires it did, and got over 20C temp rise so magnetron was working (detailed instructions online). Switch is right on top of magnetron. Tried to remove spade lugs but lugs pulled out of switch so I cut the lugs off and removed the broken switch. Screwed down new switch using old hardware. Trimmed wires back and cleaned them. Used crimping tool to put on new spade lugs from car parts store. put heat shrink over lugs and wires to strain relief and buttoned the unit up. Microwave works fine and oven baked a cake so good repair.

Bosch HMC 80251UC microwave oven combo known for its many problems. Dim LED display and others issues. This was a third round of replacing parts. Unit was working for a week. While in use the unit abruptly quit working agai. I am puzzled what else to replace now.
Replaced door switches three times. I suspect another (green Botton) switch again. The whole unit is heavy and need two people to pull out of the cabinet.

Pulled out the old piece after removing turntable and put new piece in. Then put turntable back on top.
It's a $9 part and I probably saved at least $200.
