Replaced our 7 yr. old Furrion Micro with same model. Old model number was FMCM15-SS, new model is FMCM15A-SS. So far very happy. Ordered from eTrailer and arrived in excellent shape even though box was a shambles. The hand holds on the box give way and rip apart down to the Styrofoam but not a scratch on the new microwave all wrapped in plastic. The new microwave is beautiful, has a sturdier door, larger handle, no flexing, solid feel when closing. Updated checkered pattern SS interior, bright LED counter lights, more sophisticated menu and operation is more intelligent. Requires study of owners manual - definitely. Our old Furrion micro was installed in our Big Country at the factory with a damaged lower left rear corner we couldn't see until we removed. One day, old micro just blew the 20Amp internal fuse when opening door. I tried all suggestions, replaced switches, switch mounting bar, fuses, put tape on handle ears, tried every thing. Suspect something else more complicated at play. Bit the bullet, called eTrailer, glad I did. They had 15 in stock. Interesting, I ordered from Missouri but micro shipped from Utah as we are located in Colorado. No extended warranty available from eTrailer just 1 year, no Vets discount just FAST FREE UPS shipping. New micro came with wall mount plate, which we didn't need, just used old mounting plate already in place. Removal/installation is a two person job for a 65 pound unit. Went smooth. Easy to understand the process when you remove the old one. You need to remove the decorative 4" air vent trim piece above micro, loosen 3 -3" screws on top of micro then unit drops down at an angle. Lift back of micro off wall mount bracket. Install is reverse and easy for 2 people but the 3" screws are a bit fiddly that attach from the top through cabinet into the micro. A good upgrade!
