Check for a blown ceramic fuse behind the panel. If the fuse is dark in color it is probly bad. you can get one at radio shack store or on line

Where is the fuse for whirlpool microwave MH7140xfb-1 -

The support page for model MH7140XFB1 is here. Your exploded view with parts list is here.
There is a bulletin about door switch (interlock) support holders here.
It may or may not apply.

If a fuse is blown, it can blow for many reasons, and not every problem blows a fuse.

For disassembly info, you can watch the video at this site, or see these text files: http://www.microwavecontrol.com/safety.txt
http://www.microwavecontrol.com/disassembly.txt

Unfortunately, the door handle is not available separately. You would have to order the entire door assembly.

It is part number DE94-01381J and it runs $106.99 from Sears here. (prices subject to change)

Light bulb not on and microwave not turning on. Was working fine in the am but went to warm something in the afternoon and the light wouldn't come on and didn't warm the coffee.

Hi,
Firstly check fuses in your microwave. You will have to take off the outer casing and check on the power circuit board to see if there are blown fuses.
Best wishes,
