Fan turns on by its self?

Chances are you have a bad hood thermostat or thermal cutout.

We have a service manual for a similar model on our site: http://www.microwavedisplay.com/r1380_r1381_sm.pdf

While you can't go by the part numbers in the above manual, you can use it for important safety, disassembly and test info.

You can order parts for Sharp models from Tritronics at http://www.wehaveparts.com.

You can find wiring diagrams and parts lists and order parts for most other brands from the Pros here: http://tinyurl.com/gv383.
