MW8550XL0 Whirlpool Microwave - Instructions

I didn't. Don't know how to get to light bulb to change it for this specific model

Removed the ice brucket,
Removed the light shield by releasing one screw using a nutdriver.
Replacing the bulb and reinstalled the light shield.

Your web site is one of the best and most helpfull service sites I ever used. Just wish that in the future you will ship parts overseas.

Before ordering any parts I remembered seeing a fan above the nylon roof of the microwave. I had seen a belt that drove it on a prior repair 3 years ago.

I then removed 1 screw holding the electrical panel so I could tilt it open. Since power was still plugged in I didn't put my hand in. I used a flashlight and the broken belt.

I could also see the moter that turned the belt and tested it by starting and stopping the microwave and could see the motor pulley spin when it slowed to a stop. I then closed the control panel and screwed it in place.

That confirmed I proceded to go to the internet with the model # for the rane/microwave and looked for parts.

I had an easy job looking the part and saw that the fan as I had called it was named Stirrer because it kept stirring the microwaves over the food.

Overall I looked at 2 venders and chose Part Select because they showed the same catalog page and part numbers, and they had a better price.

I had my part/ belt in 4 working days and installed the new belt in about 15 minutes. This time unplugging the range so there was no power to be concerned with. It was a matter of picking out the old belt and putting the new belt on the motor then walking the belt over the large pulley at the Stirrer since the belt will stretch a bit.

Buttoned it up and later tested with popcorn and it left only a small amount of old maids.

Thanks, Walt

The hardest part was taking out original light bulb because screws on shield where hard to unscrew after all this years . The old bulb vent out leaving neck in socket. It took narrow electrical pliers to get neck out .The generic appliance bulb did not fit and had aluminum neck ,not recommended for brass sockets in ovens.Putting new light bulb in was not the problem.

1. Unscrewed glass cover on bulb
2. Removed old bulb
3. Screwed in new bulb
4. Replaced glass cover
5. Mixed drink & baked cupcakes

very easy

Screwed in light bulb and glass protector

My husband took the plastic cover off and took out old bulb and screwed in the new one. Then put the cover back on.

I pulled down the wire around the glass cover. . . Released on end of the wire from its holder being careful to not let the glass cover drop. Unscrewed the bulb and replaced with replacement. Easy, easy.

Received the part the day after ordering. Appreciated the quick service and repair took less than a minute.

Remove the housing cover which requires removing 7 screws that hold the cover on. The bulb and the pully's that the belt goes on are visible and the belt is easy to replace as is the bulb.
