Question about Sharp R-1850A Convection/Microwave Oven
Microwave will shut down after 59 sec, time remains. Must press start again and will run 59 sec more. Doesn't require cool down. Every other aspect is working fine. Ordered new control unit and replaced but same problem still there.
Replaced damper motor twice! First replacement motor did not turn. Second one was OK, these motors are cheap JUNK. Last Sharp I buy!

Exact same problem. Very common problem with the people we know that have motorhomes with Sharpe R-1874
Mine was the damper motor. $14.95 for the motor.
The total bill for removing and reinstalling in my motorhome with parts was $106.45.

It was the damper motor. $10 part fixed it. Thanks

Sounds like someone else got it already, I just got the phone with sharp tech support for the exact same problem, and they said to replace the damper motor and switch if the board didn't do it. Good Luck!
