HMV8053U (01) Bosch Microwave - Instructions

Unplug microwave. Removed 2 screws from the top of the microwave to remove the top plastic strip carefully because the tabs can break off. Remove one screw above the control panel and one screw underneath the control panel. The control panel should come out. Take a picture of the wiring connections to help identify how to put it back toge ... Read more ther. Carefully disconnect each wire set using a needle nose plier if needed. There are 3 sets of wires that go to the 3 door switches. After the control panel is removed there are 2 or three screws to remove that hold the door latch mechanism. With the door open, entirely remove the latch mechanism. Pay attention to the 3 switches, one has a different number on it and the other two have the same number but differ by being normally closed and normally open. You can test them or just replace them. Note I ordered the 3 switches by part number but got 1 switch that was incorrect and was the same as the other one. There is a plastic tab that needs to be depressed at the bottom of the switch casing in order to get the switch out. The problem with my microwave ended up being the lever was worn visibly by door misalignment with the latch. One of the screws holding the latch in position was missing. The door was not consistently activating the lever and the bottom switch. Replaced the latch, lever and two of the 3 switches, even though they didn’t need it. Check door alignment with latch. Reassemble.

Replaced fuse and switches.This is an undercabinet microwave.
The fuse is located in top right but there is no access from the front of the microwave necessitating complete removal of the microwave from the cabinets and then taking the microwave cover off.
This is a terrible design,
Instead, I cut the vent grate on the top ... Read more right front of the microwave to access the fuse.
replaced the fuse.
Switches were relatively easy to replace...being careful to not pull wires out of connectors or breaking small plastic tongs and clips.
Microwave is still blowing fuses though. door alignment may be off.
Again, terrible design and lousy product quality.

Fished out broken tabs. Replaced with new grille from PartSelect and inserted two top screws.
PartSelect replacement was prompt and appreciated.

Followed instructions in the manufacturer's manual

This was easy. Simply dropped the new replacement parts in place.

No tools required,simply inserted the drive coupling onto the drive shaft at the bottom of the microwave and then placed the turntable ring underneath where the turntable sits.
