A:AnswerHi Sam! It sounds like your microwave might just be in demo mode. This mode is used by retailers to display the unit, as the unit will not heat in demo mode. This link (https://bit.ly/3vF7OKL) can walk you through how to turn off demo mode. It also has information on what to do if the microwave is still not heating. ^Jecca
A:AnswerI'd like to help with this. Here is a link (https://bit.ly/3v5Wl6C) to the mounting bracket for this model microwave. It also lists all the other models this bracket is compatible with. If your previous model is on the list, then both models use the same bracket. Alternatively, if you would like to leave another question with both microwave model numbers, I would be happy to check if they use the same bracket. ^Jecca
A:AnswerGreat question, kathy! According to page 26 of the user manual (https://bit.ly/3szOn4j) both the cooktop and oven lights use 40 watt bulbs. ^Jecca
A:AnswerI just purchased. Not used yet. When installed it came with 2 filter screens for lower vents over stove top. It also included a 3rd screen for outside venting above microwave, if installed, but mine is not. I hope this helps your decision.
A:AnswerThanks for asking, maude! Because this model is designed to be an over-the-range model, it does need to be installed in a mounted position, with the underside open for proper ventilation, prior to use. ^Jecca
