MH1170XSB0 Whirlpool Microwave - Instructions

Replaced the intake grille. The grille should be removed prior to cleaning. The entire part is plastic and easily broken so that the two tabs for the mounting screws are shattered and will not hold the part in place. If one attempts to clean the grille using only a moderate amount of pressure with a cloth the fragile plastic will break. The part is poorly designed. When the vent is removed to replace the charcoal filter, one may discover that the grille has already been broken in a previous cleaning operation.

No repair- just replaced glass turntable.
Right part I needed with first try

removed old grill with screwdriver and added new one

The nightmare was that this microwave is installed under the cabinet....in order to get to the light bulb I had to pull out my stove then squeeze into the space between the stove and counter....my old microwave light bult was much easier to change.....Shame on Whirlpool for making this so difficult.....must be a better way to cover the light bulb so that we do not need a screwdriver to remove the door to get to the light bulb

Removed 1 screw, removed "burnt out" bulb and replaced it with new bulb.

PartSelect had the turntable I needed at the best price. Ordering was easy, but best of all, the part was delivered next day. I was able to insert the new turntable plate into the microwave and it was good as new.

when removing the bulb the base broke off and there was an ark took place as I had made a mistake and didn't unplug the unit before working on it , thought with the light switch off it was ok, but still had power in that area . So ALWAYS uplug before making repairs.
The whole unit was dead and I checked for power at the plug and it was live. after unpluging I took the main control panel off and discovered a fuse was blown and replaced it along with a new socket and bulb and now it works like new . the fuses are inside small plastic capsuals so I back probed them with continuity light to find the blown fuse .
It was quite simple once I found how to get the panels off. Just basic common sence will take care of most appliance problems
thanks

Opened the box and popped it in. No problem with that.

The part was sent to me the next day! And it was the right part. Awesome!

set the table on the support ring

This is the second replacement tray we have in installed. The first one ( Not From Here ) we had for less than 5 months, we made a bag of popcorn, and about 5 minutes later we heard a crash, not knowing where the noise came from we dismissed it. The next day we opened the microwave a saw the plate had shattered. So we hope that this will not do the same thing.

just screwed in the new part

My unit is a wall mount/cabinet/built-in model. The repair is actually fairly simple once you determine that the actual microwave is just a component of the entire unit, and that it (the microwave) can be easily removed from the unit. I did not figure this out until after I removed the entire unit (disconnect the power supply, lift the entire bulky, heavy unit out of the cramped space in the cabinet, etc). Once I got it out I figured out how easy it is to remove the actual oven - a couple of screws, literally. The unit is a bit bulky, but not particularly heavy and is quite manageable. I did this entire process alone.

I got the oven out, rolled it on it's side and found the plate to access the motor. The plate is located on the bottom/underside of the unit. The plate is nothing more than a section of the underside of the metal housing that has been cut-out as an access point. This "cut-out" is not complete - that is, not completely cut out so as to all the plate to stay in place without the need for screws, etc, until you actually have to use it. I used a pair of dykes to cut the couple of points still connecting this plate, removed the two phillips screws to remove the motor, disconnected the two wires connected, then reversed to complete the repair. You then flip the cut-out plate over/rotate it, and some screw holes line up. Find a couple of small screws, and re-attach the plate to cover the motor.

The actual fix is really easy, again, once you figure out the simple way to remove the oven. I am an idiot, so you will probably find this much easier. I could probably do this repair now, after my experience, in less than 30 minutes (probably less than 15 minutes). I probably save a couple hundred $ by doing it myself so was well worth the time to do it. Good luck.

removed two screws,lowered the glass shield,removed the burned out bulb and replaced it with the new one. I ordered the bulb from parts select and recieved it two days later. It was a pleasure to deal with them, and certainly use them again.

I had some difficulty removing the glass plate because of the awkward (upside down) position of the screw that retained it. After replacing the burned out bulbs and replacig the glass plate the problem of replacing the screw involved my dropping the thing several times before I got the screw threads to catch. I got a screw thread to catch enough to hold the glass plate in position and left it at that.
