I need a manual for sharp model r-303cw


I haven't found the instruction manual available as a free download online. However, there are several places to buy a copy. Sears Parts Direct has a printed copy for sale for $4.49 here: http://www.searspartsdirect.com/partsdirect/part-model/Sharp-Parts/Microwave-Parts/Model-R303CW/0958/0123245/50022360/00001?blt=06&prst=&shdMod= . The current part number is IB-R303CK. Searching for the part number gave several other sites with the manual available.

The Sharp R-308K is a very similar microwave and that manual is available as a free download. See http://www.managemylife.com/mmh/owner_manuals/7167/SHARP-Countertop-Microwave-L0906397?brand_name_search=Sharp+microwave .

I hope this helps.

Sharp microwave 1200 watts keypad showing


Not a complete answer, but may help describe problem: Our R-510B should be the same except for color, and for several years it has intermittently messed up its display. The left side two segments on the units digit won't light up. So a digit 8, without the two vertical bars on the left, comes out as a letter E reversed left to right. Any digit that uses the two left segments (traditionally labelled segments E and F when talking about 7-segment displays) comes out wrong. Every thing else works fine. I can't tell if this is your problem.
This is almost surely a bad contact at the interface between the LCD display panel and the PC board: Typically there is a "squishy" conductive strip that connects them, and I expect grease has gotten in there. If so careful disassembly and cleaning with a mild solvent should fix it. Since we can live with it, and it usually fixes itself in a few weeks, I have not got around to taking it apart.

Hi our Sahrp Carousel microwave LCD panle display is not working


You have to replace the control board. Sharp has had problems with the display boards for awhile. There is no bulb or fuse you can change.

Found the answer by calling a Sharp technician and they said it was the magnetron tube, which is not worth fixing :( Thought I'd pass this on to anyone that has yet to find out.
