Question about Sharp R-1870 Convection/Microwave Oven
is a problem in one of the damper-related components, either the switch or motor or the damper door may be binding.
The damper is a door inside that opens or closes depending on cooking mode. If the controller senses that the door is not in the right position, it will shut down the cook cycle.
Sharp models stop after 59 seconds.
See the attached sample drawing for a typical damper assembly.
