Question about Sharp R-820B Convection/Microwave Oven

1 Answer

The display on my Sharp R-820 BK convection microwave no longer displays! It flashed between the usual brightness and quite faded brightness for a few days. Now it is so dull as to be all but unreadable. The unit seems to function fine otherwise.

When the unit is turned on it shoots flames from the roof of the unit WHY?


It sound like the antenna behind the plastic plate may be warped and touching the cavity. From my experience when they start shooting sparks it is time for a new microwave.

The service manual is here:
http://www.microwavedisplay.com/r820bc_bk_bw_sm.pdf

You can get Sharp parts from Encompass here.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
See http://www.microtechfactoryservice.com/cap_test.html

If it went dead several seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
See: http://www.microtechfactoryservice.com/xformer.html

If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

The display no longer works on my Model R303CW Sharp Microwave. Is there a part that will fix the display?? Everything else works fine.


Nope , could be dry joints or corroded pcb or defective display driver or supply ? Only can be told once opened and inspected.

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

Sharp Microwave R-950A


Chances are your thermistor is defective.

This UK model is probably similar to the US model R-930 or R-820.

We have both service manuals at our site and while the part numbers will not necessarily be the same, they will be handy for safety, disassembly and troubleshooting. They are here and here.

When you're ready to order parts, visit Sharp UK for spares dealers and servicers.

We're happy to help and we appreciate your thoughtful rating of our answer.
