We have any microwave techs on the site ?.
Have a Sharp, model R-1480.
Produced in March 1999 & in a 1999 H/R Vacationer.
When trying to use Micro, set time, press start & micro will turn light on & count down the minutes like normal, but the turn table will not rotate or heat what your trying to heat up.
Has a setting to turn the turn table off or on & is set for on.
This unit, looks to be like a custom style unit for RVs, because of the way it is mounted in the cabinet space & includes an exhaust fan above for the gas cook stove.
Thanks in advance, Neil
