Sal I noticed on the infinite switches, some of them have longer rods sticking out. My stove uses the shorter ones on the infinite switches; otherwise the knob sticks out too far. How can I ensure I get the shorter one? it's for the larger burner on a Whirlpool electrical range. I had bought one a few years back, on ebay, but it was too long, and the knob sticks out further than the rest... . I ordered a 3149400, which said it was the same as 3148953 & 3148954...
Answer Sal, A model number would've been more helpful, but. Both switches WP3149400 / 3149400 and WP3148953 / 3148953 are for 8" burners, the difference is the WP3148953 has a 3/4 - 5/8 in. long shaft and the WP3149400 has a 7/8 - 1" long shaft. Measure the shaft length of the original switch to determine which switch you need. Thanks, Read More... Answered by AppliancePartsPros.com | Friday, April 7, 2017
