I now have the same problem as described in the following post.
Sharp Microwave Oven R-1874 Circa 2004 removal
Since I can no longer reply in that thread (its says the post is 900+ days old)
I am posting here...
Here is my problem.
I have located the parts needed in the US (Damper motor and switch)
The parts are priced reasonable, but the shipping cost is a rip off to Canada
Any other Canucks out there find a better way to get these parts...Please Advise...
