How to Troubleshoot & Replace Whirlpool AP5331849 / W10450187 Vent Grille

Took broken shelf door out put new one in. Nothing to it. Very easy . Part came in 3 days regular shipping. 

Found OEM item at best price with ApplianceParts Pros and ordered it. Usually some apprehensions about using online the firs time but reading reviews helped move me along....really glad it did. Their rep I spoke with was very helpful, item shipped right away, received in 2 days and is now installed. 

Replaced part. 

Ordered a new grill (with clips) and popped it on the front of the microwave by hand. Done. Part delivery was super fast. 

I entered the model number in your web site and the part I needed was listed. I ordered the part and it arrived in just a couple of days. When I opened the box there was a page of instructions, mostly pictures. The grill was installed in just a couple of minutes. 

I thought about buying a new grill, but did not know where to go. Looked up brand company and checked part number from my original instruction booklet. Referred me to ApplianceParts Pros.com. Found grill part I needed ordered on line at less than $30 ( Far less then buying a new micro and paying also for installation) It came in less than 3 days. I unpacked it, snapped it on and good as new. Thanks App Pro. 

Ordered new grill from Appliance Parts Pros and repaired myself. Appliance Parts sent correct parts very quickly - excellent service 

Bought a replacement grill-vent. When the replacement part arrived I just put it in (less than 30 seconds). Extremely easy and trivial installation. 

I ordered a microwave vent from appliancepartspros . The vent arrived within a few days in perfect condition. My husband installed the microwave vent within minutes! 

Replaced the whole vent
