Please help with the problem

I have the above product in my '05 motorhome & it is an over the counter convection microwave oven. It shuts off after 59 seconds & I have to hit the start again for remaining time or another 59 seconds. I've had the motorhome since new & the only problem with the oven. Thank you, Gary R Whaler

This is a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door. The damper is a door located on the right side of the innards. The damper closes and opens depending on cooking mode. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find an exploded view by entering your model number here: http://www3.sears.com You can order parts from Tritronincs at http://www.wehaveparts.com
