MH6140XKB1 Whirlpool Microwave - Instructions

Piece of cake. One screw to release the dropdown light diffuser. Just remember, the you're screwing the new bulb in from a reverse perspective. Also this site sends the correct part the first time.

Put s pot under were you take the screw out.If you drop it you can get it easy

Finding the part was the most difficult as this is a very old microwave. I spoke to a really nice lady and we figured out that even though it was not the exact dimensions of my previous film that it would certainly fit since it was just a little bigger that what I had. Once I got it lined up correctly, it was really easy to put on after I removed the backing and took off the old film which wasn't difficult either.

Unplug microwave! It's NOT necessary to remove microwave from above stove. Removed two Philips head screws on top front of unit to remove front grille. Removed one screw to remove control panel, letting it hang down. Found inline fuse in cabinet where line cord wires come in. Pulled out blown fuse with thumb and forefinger. Snapped in new fuse, replaced control panel and grille with the three screws. Plugged in the microwave. -Worked great! Good opportunity while grille was off to clean it and replace the charcoal filter inside the cabinet.

Really easy for a 75-year old female; just spent more time reading the online manual than actually installing the light bulbs to find out where to access the light bulbs.

Turn off power supply at breaker . Replace old bulb with new bulb .

We needed a phillips head screw driver to remove the single screw holding the light bulb cover in place.
Removing the old bulbs was a little work, because they had come loose from the sockets. We unplugged the microwave, so we could grip the sockets with a tool. I think my husband used a needle nose plier for this.
The new bulbs screwed in easily, and then we refastened the light bulb cover with the phillips head screw driver.

Opened Box and Replaced Part......No Problem!

Husband replaced the bulb

The power on the microwave went completely out when I went to use it, but there was no power failure for the house or neighborhood. We removed the microwave from above the oven. Took out the screws on the sides and back of the microwave and slid the top back. The line fuse was located on top unobstructed, NOT behind the button panel like some microwave models. As the appliance is over 20 years old the line fuse was quite old. It was really hard to pry it out of its holder and actually broke. I used a vacuum to suck up the dust and glass and it was easier to get out the ends once the middle broke. Popped the new line fuse in, slid the top back on, put in the screws and put the microwave back in its compartment above the stove. Good as new!! We were about to spend money on a new microwave, but thankfully I came across this site. So happy I did!!

This repair was really easy. The part that took the most time was taking it down from it's compartment above the oven and putting it back up there once repaired.

Pro tip! Check how many bulbs you need before ordering. Mine only needed two. I got two. I suspect I’ll buy a new microwave before new bulb burns out again. Ordering/delivery was fast. No need to have spare on hand.

Pulled unit out, pried the bottom plate off the unit. Mine was not screwed in, but designed to be pried off, and then replaced. That was a surprise, but not very difficult. Unscrewed the motor, unplugged the electric connection, replaced it with new part . Replaced the bottom plate and tested the machine.

Spouse just screwed in the new bulb and reinstalled the light cover plate with the two screws. Took under a minute. Works great.

Had to remove unit from above stove, this step will take the longest. With unit on table cushioned with a throw rug under it . I removed the case and located the magnetron removed 3 screws, unplugged unit with a needle nose pliers, installed new unit plugged it in and checked the microwave with a cold coffee cup of water . Worked great! Heated great!
