This 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.

We have the applicable service manuals for these models and have uploaded it to our site here and here to help you.

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

This 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.

Please include FULL model number*, FCC ID number*, + detailed symptom information. ( * on the tag in cooking cavity or around door frame or control frame or on back)

Sharp microwave r1870 only runs for 59 seconds


If it consistently runs for exactly 59 seconds, and shuts off, it's probably the control panel.

If it runs approximately that length of time, you might have a defective thermal protector on the magnetron, or the magnetron is running too warm for some reason.

My Dacor PCOR30 only works 58-59 seconds at a time. I've read this could be a control board issue (part No. 66660). Is this correct? Is there any other possible cause?


Not likely.

This 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.

Dacor-branded PCOR30-series microwaves are just cosmetically altered versions of the Sharp R1870-series ovens.

These Sharp-made models stop after 59 seconds when there's damper toruble.

See the attached sample drawing below for a typical damper assembly.

We have the applicable service manuals for the Sharp models and have uploaded it to our site here and here to help you in disassembling and troubleshooting your Dacor version.

You can find the Dacor PCOR parts list here and you can order Dacor parts by part number here.
