Whirlpool W10843943 Air Damper OEM Part

Bought a new home with microwave venting into kitchen. Ordered damper assembly needed to vent through the wall to the outside. Removed microwave, followed directions in original installation instructions, turned fan over, cut hole in wall, installed wall cap and replaced oven. Problem solved.

My friend completed the damper installation. It went smoothly without any issues.

Found all parts on Appliance Parts Pro web site that I needed, Their prices were unbeatable, couldn't believe the fast shipping.

Had water leaking in from warm air condensate in vent pipe. Took down microwave with screwdriver and second set of hands. It is only held up there with two bolts and a rear channel. A damper to block the constant air flow up the vent had never been installed. I ordered the part from appliance parts pros and they shipped it literally in less then 2 days. Installed damper in 1 min. I would have been done but realized why it was never installed. Had to work on widening hole in upper cabinet as they missed the connection to damper and had to trim back excess vent stack to fit to damper.

Using this damper assembly I was able to connect the microwave to the outside duct and vent it properly. Huge difference in our kitchen!
