|Our 5th wheel trailer has a Sharp Microwave, Model R-312AK, built in above the range hood. According to the label it was manufactured 2/2004.
At the start of this year's camping season, noticed that one of the LCD bars was out but everything else worked fine. A day or so later, all the bars seemed to work correctly. Later this summer, similar situation, but more bars were missing, but again a few days later the display seemed fine. Last trip out this weekend, about half of the bars were missing and did not come back although the unit seemed to work fine. At home with the trailer plugged in, most of the bars are missing and even though it hasn't been more than a day, I don't have any hopes of another miraculous recovery.
I have three questions. First, is it likely that there is a connector that has loosened with all of the over the road vibrations the unit has seen, or are there other more likely (and expensive) problems? Second, if the problem is likely to be a loose connnection, is it possible for a handy mechanical engineer (who doubts the existance of electrons since he has never seen one) to open the unit and reseat the display connectors? Most sites give dire warnings about frying onesself if they dare tamper with the inside of a microwave.
Finally, if the problem isn't user fixable and the $150 unit is not worth an expensive trip to a professional to fix, does anyone have knowledge about the Dometic unit which says it is designed for the harsh environment of a trailer? Or is this just marketing hype? I can buy one through a local Camping World store that is the same size for about $140 with a three year manufacturer's warranty.
I have searched the forum and did not find any information that seemed applicable to my situation. Any help the most honorable members of this forum can give would be most appreciated.
