Product review (5 stars): Timer Replacement for a Roper Dryer
Ordered this replacement part for our Roper dryer, which is made by Whirlpool. The old timer had been failing for quite a while: we had to jiggle the timer knob to start the dryer and eventually, it stopped working no matter how much we jiggled and adjusted the knob. Ordered and installed this replacement two months ago and it's still working perfectly. I have ordered other appliance replacement parts from Amazon and I have always been very happy with the product quality and quick delivery.

UPDATE: this part lasted 4 years, which I believe is pretty good for the price. We do an average of 5 loads of laundry per week and we didn't make any effort to be gentle when setting the timer, so no complaints about the durability. We ordered this part again as a replacement.
