How I Fixed Our RV Convection Microwave Oven
Living on the road without an RV convection microwave oven becomes a real challenge, not only when a park has insufficient power to run it safely, but even more so when it’s kaput! Earlier this summer ours started acting funny. It would run for 59 seconds then quit, but would resume for another 59 seconds if you pushed the start button again.
A little online research provided the reason our Sharp RV convection microwave oven was acting this way. A simple replacement of a failing part would fix it. No problem; I found the part online and ordered it. Within a couple of days the part arrived and it would be a simple task of removing the oven from where it was mounted above the stove. Once removed all I would have to do is take off the shroud covering the internal workings and swap out the offending part.
After reviewing the oven’s owner and installation instructions, I was convinced the process should be easy-peasy. In reality, it was anything but. It seems the installation instructions for the unit were for residential purposes. The RV manufacturer went a step further to ensure it stayed where it was mounted even when subjected to road stresses. What the motorhome manual and the oven manual skipped was was how they did it.
Peering into the top section of the oven, once the front covers on the oven were removed, I could see there were additional screws and brackets mounting it to the ceiling of the slide, but there was no way to access them. A piece of wood trim above the oven fills the gap between the oven and the ceiling. Searching for a way to remove the oven was perplexing … I couldn’t find any screws and it was snugly in place. I pondered the problem for days … maybe even a couple weeks which wasn’t making my bride any too happy. She likes cooking in her RV kitchen and desperately wanted her oven back!
How Was I Going to Get that Oven Out?
I searched online for answers, even asked a couple RV service shops and techs … but no joy. None had ever removed a microwave setup such as ours. In for a penny, in for a pound … I decided to see if I could just remove the trim piece by force if necessary. Slipping a thin putty knife between the ceiling and the trim piece, as well as between the oven and the trim piece, revealed there was nothing fastening the trim to either ceiling or oven. So with a gentle tap on one end of the wooden trim piece with a hammer and a block of wood I committed to removing it by force.
To my surprise it was only held in place by friction! It was wedged in tightly between the ceiling and the microwave oven. It popped right out unscathed. Whew! Now it was a matter of following the oven’s mounting instructions to remove it and the two additional screws the RV manufacturer used to fasten it in. Four screws…and it tilted forward and down. All I had to do was lift it off the lip rail on the wall and set it on a table to work on.
I removed the oven’s outer case and that provided me with access to the control motor I had to replace. I had the right tools (shorty screw driver) to remove the mounting screws that held the part in place, but my hands were a bit large to work in such a tight space. Still, I managed to replace the part and close up the oven in about thirty minutes.
Putting the oven back in was quick, too, and I had it reinstalled in about as much time. I ran a couple tests before replacing the trim. That was done simply by tapping the wooden piece back into place. All was good, the wife was happy we once again had a functional RV convection microwave oven.
Notice…installations will vary by manufacturers of both the RV and oven.
