Question about Sharp R-1874 Convection/Microwave Oven
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.
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.
