David O Webster , MA October 29, 2022 The control dial was sticking such, that turning the knob was very difficult. It felt like it could break. I replaced the controller (Timer). The timer order was promised to me in 10 days, but it arrived the next day. I installed it very quickly and it was a perfect replacement. No modification was required.
