Jenn-Air Switch-Fan
Genuine Whirlpool part
By: Whirlpool
Part Number: WP7403P876-60

For switch mounting nut, order part# WP422617.

Do-It-Yourself Stories from Customers like You Broken fan switch   Darrell Q. • Leesburg , VA • May 09, 2016

This replacement part looks nothing like the original because the original is two parts, the replacement is one part. The original has a switch with 3 wires coming out of it that go into a "block" screwed to the bottom tray. And this "block" has 2 wires that come out of it going to the fan. With the replacement, the block is eliminated and the 2 wires go directly to the switch. Easy install. Read more
