i noticed that our microwave was dropping down, with a finger width gap between it and the bottom of the cabinet. I guess 17K miles of Western US highways caused the bolts to loosen over time.
To fix, you’ll need to:
- Remove the upper cabinet door hardware and door
- Remove the back corner panel that hides a bundle of wire connections
- Pry up the cabinet bottom
- Tighten the two bolts
- Put it all back together
A putty knife, thin blade screwdriver, and wide blade screwdriver made prying up the cabinet bottom easy, while protecting the wood. An offset screwdriver made tightening the bolts easy to do, without totally removing the cabinet bottom.
