What is it with the microwave ovens in the 184 BH? First time I took the (almost) new TT camping, I discovered that the magnetron wasn't working in the microwave. Since I opted out on buying the warranty insurance, I replaced it with a Magic Chef. It is the same, exact configuration as the unit it came with, and I was able to use the same surround panels and exhaust diverter. I took the housing partially off the old one to make sure I didn't drill into vital parts when installing the surround panels. I wanted to just switch the housing on the units, but the front housing seam is machined bent/pressed around the top front of the microwave oven, so drilling holes became my only option. It works great and only cost me $58.00 to replace. The only difference between the two microwaves is the location of the top exhaust vent. The dedicated RV version microwave would have cost me $200.00. I wanted to put in a convection microwave, but they require more wattage, are larger and generate more exhaust heat, so I stuck with the 900 watt microwave.
