Question about Panasonic NN-S254BF Microwave Oven

1 Answer

Sharp mdl R-1870 convection microwave runs for 1 min

The microwave runs for 1 min and then stops if you press the start button it will run for another min then stop. So if you put 5min on the timer you have to stand there and push the button 5 times. Any thoughts on this

Thanks

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.

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.

Sharp micro counts down 59 seconds and stops


It seems this has been happening over the last few years. I am a retired appliance tech. My 1870 also started the 59 second routine, Also in a motor home. Pure logic. Had to be the board. New board same results. So now I need to run down a parts manual and possibly service manual, and get the damper switch and motor refered to in earlier posts. Changing out the board was fairly simple. Dropping the unit to change out the other components sounds like it will be a tad bit more difficult.

Sharp 1870 just quit cooking and no turntable


The fact that the microwave and convection both do not heat indicated that the oven is in demo mode, check the user manual, otherwise it will possibly be a relay not triggering, may need a pcb replacement, check Demo mode 1st....Phil

59 SEC NEED TO GET FRONT OFF MICRO


If your unit runs for 59 seconds then stops, the problem is the convection damper motor. (Sharp part # RMOTDA222WREZ).
Unfortunately, you cannot access this from the front - the whole unit has to come down as the entire outside cover has to be removed.
This is a pretty major job and the motor (located below and behind the magnetron tube) is rather hard to remove and get back into place. This is probably better left to an experienced technician. You can call Sharp 1-800-BE SHARP for a referral to an authorized servicer.
