Question about Sharp R-1874 Convection/Microwave Oven

1 Answer

Sharp R-1874F Low Convection Temp

I can't get the convection temp to go above about 300 degrees.  I can get higher reading immediately next to the heat vents on the left side, but anywhere else in the oven stays much cooler.  Food is not cooking properly.  For example, a 6 lb ham, after 2 hours at 375 reached an inside temp of 70 degrees.  The oven never reached 300 degrees on an oven thermometer.

We have the 2 service manuals you need to refer to for this model and have uploaded them to our site here and here to help you.

You will need the
free Acrobat Reader to view or print them in case you don't have it.

The manuals have a safety info, disassembly info, troubleshooting chart, test procedures, part numbers, etc.

I would first suspect a bad thermistor, but it should be checked, as well as the line voltage at the outlet, etc.

The best place to order parts for this brand is Encompass (formerly Tritronics). Or you can call them toll-free at 866-779-5835.

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

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.

I have a sharp over the range convection microwave modelr-1874F The convection works but the microwave sounds like it working, the turntable turns but it does not heat the food we tried unplugging it for...


Every time the microwave part of an oven do not heat it normaly means a faulty MAGNETRON (the device that produces microwves) unfortunately if it's the magnetron they are allmost as expensive as the oven it self, you could allways check for a burned fuse, (allways be prudent opening an applyance)

Good luck!
