The clock is part of the control board and cannot be repaired as a separate item. Most replacement control boards costs as much as
a new microwave.

put a cup of water in the cavity and set for 1 minute, after which time you can feel the temperature. Switch to the other power setting and repeat with a fresh cup of water. This will either be hotter than the first or much cooler. Most microwaves use 100% power for full and 30% power for defrost, with 50% usually being lower or medium power. Straight-forward physics. The more power the hotter the water becomes. Hope that helps.

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.
