This may be due to the microwave section not working. Check the high voltage diode if it is ok, replace the Magneton.

The control panel of my sharp grill 2 convection microwave oven is very dim


Hi,
Dimmed light might be caused by a slight contact between the panel's connector and the mainboard. Or, there is a dimmer option (feature) in the menu. Depends on model. Some of Panasonic microwave ovens are equipped with such a feature.
Regards,
Dan

Is the sharp above range microwave model r-1871t recirculating?


According to the Sharp product site, http://www.sharpusa.com/ForHome/HomeAppliances/Microwaves/Models/R1871.aspx , the R-1871 is a convection and microwave oven. The manual describes using the convection oven feature on page 18 (page 20 of the PDF). The direct link to the manual is: http://files.sharpusa.com/Downloads/ForHome/HomeAppliances/MicrowaveOvens/Manuals/mic_man_R1872.pdf . The convection button is on the top left in the middle group of buttons. You use the numeric power level buttons to set the oven temperature. When you program convection cooking, the 1 button will bring the oven to 100 degrees F. The 6 button gets the oven to 350 degrees F.

I hope this helps.

Glass turntable in tricity tmc209 says "microwave only" What do I use for convection or combi cooking? Does turntable still need to rotate for convection cooking?


definately dont use the standard glass plate for convectional 'oven' cooking, as it will shatter. i have had TWO plates shatter so far before realising they should only be used for microwave cooking.

Sharp model R-1871 shuts off every 59 seconds


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.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

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
