Ordered top & bottom micro-switches and mounting plate parts. Internet reviews could not find specifics if the issue was due to a top/bottom or combination of micro-switch or mounting plate failure. Pulled the plug. Removed the top vent assembly cover held in by 2 Phillips screws inside the vent. Removed the control panel held in by 1 P
... Read morehillip screw at the top vent assembly area. Lifted control panel upward to release the catch and moved it off to the side - didn't disconnect any leads. Used a Torx bit to remove the door switch mounting plates at the front and pulled the plates through the opening from the control panel. Documented the wire color code connections, the top plate uses 2 micro's with one using both the closed & open contact. Installed the respective micros on the mounting plates and worked backwards with the wiring and removal steps. Once completed, the open/close sensing has worked every time.
I first went back Lowe's where I purchased my microwave in the hopes they would help in the ordering of the grill vent for my mircrowave. They advised me that they do not order parts and gave me a card of a company to call to order the part. I called the number on the card and was left on hold for 20 minutes then instead of helping me wit
... Read moreh the part I needed they proceeded to set up an appointment for someone in my local area to come to my home, order the part the later install. I knew that it was just 2 screws and bottom snaps to install and I didn't want to wait a week for someone to come to my home. I then went direct to the Whirlpool web-site and found "Partselect.com". I was unable to match my model# even though my microwave was only 13 months old but knew it was probably interchangeable with another so I then called "Partselect.com" and was just amazed at how helpful and knowledgeable the gentleman on the other end was. He found my part and was very patient in describing it to me to assure that it was the correct one. I was on the phone less than 10 minutes with him. The part came in 3 days and was the correct part:) It took me less than 5 minutes to gently snap the 2 bottom tabs in and screw in the left and right tabs on top. Thank you so much "Partselect.com" for making what could have been a timely and expensive part replacement be so very simply and inexpensive.
