Question about Sharp R-1870 Convection/Microwave Oven

1 Answer

The oven/microwave turn off after about a minute

We have a Sharp R1870 convection/microwave oven in our RV, and today, the unit turned off by itself. When restarted, it keptm on turning off after a minute of use. It produced heat, and the blower still worked, but it kept on turning itself off. Can you help us?

    My microwave stops operation after 59 seconds. No matter how much time you punch into the timer it will do complete operation for 59 sec, and stop operation. However, you can punch start again and it will go 59 more sec until you reach your set time. My microwave is mounted in an RV.

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.

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 Sharp Micro Convection Model R1870 fan behind the touch panel keeps running for 50 seconds after the microwave turns off,. this is not the vent fan. it also runs for 50 seconds when you turn the...


If the fan seems to run even after the microwave had completed the cycle, then it is possible that the drive to the fan is having a time delay. Also it has to be made sure that the magnetron has been cut OFF power or else it is not a good situation. You will have to remove the control panel and check on the board, check the drive to the fan, since the processor cuts off the fan and magnetron at the same time the fan circuit must be traced. Look to the circuit after identifying the fan wiring and back check using a multimter if you are able to trace. If not take help as this can be harmful in case the microwave works till the fan cuts off. A faulty capacitor on the board can create this time delay.

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 Microwave Oven over stove fan goes on by itself


Please note that FixYa is not currently notifying us Experts when Clarification Requests are answered.

So please post a
NEW question, and please include your brand name and the full model number from the tag in or on the unit, as well as the answers to these questions:

Which fan is it?

The
internal cooling fan, which comes on automatically whenever the unit is microwaving?

Or the hood vent exhaust fan which you can turn on and off manually?

Or the convection fan, if it is a convection model?

When is it coming on?

Is it coming on whenever you cook on the stove top?

Thanks!
