Gang,
Our coach, an '04 Itasca Horizon, 36GD with the C-7 330HP CAT, has a Sharp microwave/convection oven, over the stove. We've owned the coach now for right at 4 years. That oven, has been working flawlessly for the total time we've camped. But, on a recent stay at Wahweap RV park and campground at Lake Powell, it started acting up.
Long story short, no matter if you were microwaving or convection cooking, the timer for countdown operations, would cease at "59" seconds. It did this consistently. If you were to push the START button after 50 seconds, it would continue the countdown. Then it would stop at another 59 seconds. So, I inquired about it and found out, that the Sharp unit, around my serial numbers and year, had that as a semi-common problem.
I was lead to a link that explained the issue and, what it would take to remedy it. In all reality, it's a simple and, fairly cheap fix. There's a DAMPER door inside that must be opened and closed to help regulate temps inside the unit. And, what opens and closes it is a small motor, about the size of 4 silver dollars (remember those?) stacked together. And, there's a micro-switch that's incorporated in that operation too.
Apparently those little damper motors go bad and, sometimes the switch does too. So, I found out there were multiple places to order those two items. I did so and received them in two days. I replaced the bad ones with the new parts and bench tested the unit. It works flawless again, yahooooooooo!
So, if any of you have an RV, in the '04, possibly maybe a year earlier and a couple of years after, that has a Sharp Microwave/Convection oven, and, it starts to malfunction in the manner in which I explained, there's a cheap fix.
