Mylene B San Antonio , TX January 24, 2015 Appliance: Model 3187767 Some of my stove's control knobs were broken This is probably something pretty common in a cooktop that is more than 15-20 years old. My husband had located a place in town that MIGHT have the part, but I got impatient waiting for him to make the move, and in the meantime, he forgot the name of the place. So I went online, and while the price here was more than I wanted to pay, I didn't find any other place that had a lower price, much less with a promise of the part number matching. So, I went ahead and ordered. I can't complain about the shipping time: it was scheduled for delivery later in the day, on MLK Day, and two days later, the control knobs were on the stove and doing just fine. It was merely a matter of figuring which way to put them on the valve stem. Repair complete! Read More... Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
