The timer and knob broke Elizabeth L. • Bartlett , TN • June 07, 2016
We watched the video on this website on how to change out the old timer (the plastic part had broken off and it wouldn't turn). My husband changed it all out in about 15 min. Saved us a lot of money as we didn't have to call a repair man!

Broken selector knob Gordon P. • Elgin , IL • September 15, 2015
Very easy to install the new knob. Mine had broken and the metal sleeve was still attached to the selector shaft. The sleeve was easily removed with a pair of needle nose pliers and the new knob slid right in place.

Do-It-Yourself Stories from Customers like You
Snapped off two of the selection knobs shearing off the plastic shaft which was part of the entire temperature and finsish guard switches Robert J. • Wexford , PA • September 19, 2014
I needed to disassemble the entire top control panel to get access to the switches that were broken. Once I was able to take the unit apart, replacing the new switches was an easy installation. The majority of the time was taking all the components apart to get access to the broken switches.
