Removing over the range Daewoo microwave

Question

I need to remove my Daewoo KOT-21UW over the range microwave oven to take it into the shop to have the thermostat replaced. My wife accidently run the unit with nothing in it for 15 minutes. Now everything operates except the microwave no longer cooks. The local service shop said to bring it in for repair but I no longer have the manual, and as it was installed while we were having out kitchen rebuilt, I was not the person that installed it. I don't want to take out the wrong screws and not be able to re-install it. Do you have a manual for this unit? Thanks.
