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 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 photo 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.

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.

Kenmore microwave (2 y/o) will stop soon after you hit start.

A quick test. Switch off power then remove outer cover. Look for the transformer. remove the two wires connected to the primary side. Note, do not toutch anything else. power still sitting on the cap. With those two thin wires disconnected, make sure they are not toutching each other or leaning on the metal frame. Set a program that has been a problem and let it run. If it still stops and does what its not supposed to do, your board needs replacement.

When you close the oven door the latches operate a couple of interlock switches that control power. It may be that one of the door switches is bad or out of adjustment. It's also possible that one of the door latches is broken so it's not hitting the switch. There should be two door latches. Are they both there? This oven could be fixed by adjusting or replacing the interlock parts as needed. Because of concerns about microwave leakage from an improper door seal, you should have this oven serviced by a professional.
