Whirlpool W10843943 Microwave Vent Damper Genuine Original Equipment Manufacturer (OEM) Part for Whirlpool, Maytag, Kitchenaid, Amana, IKEA, Jenn-Air, Estate, Roper

Way to expensive

I needed this to install an outside vent on my microwave. It's a cheap piece of tin. The baffle jams so I removed it, the outer vent has one. If I had to do it again I would have made one out of tin.

I added an external vent to my existing microwave and needed this to mate to the exhaust vent. It works as designed. Lower stars because it is over priced and cheaply made.
