sometimes the timer knob moves and dryer shuts off normally and sometimes the time doesn't move at all and runs until manually shutting off. Will a new timer resolve this problem or could it be something else?

Whats the model# of your dryer smonski? Its located inside the dryer door or on the top console.

Does this happen on auto-dry or timed-dry?

Thanks. My next question is how do I install it? 30 minutes? Would you buy a used timer at half the price?

Nope, never buy used parts, thats a big NO-NO in the appliance business.

To install it, just remove the end cap console screws#8 then the console will slide forward and lift up, then take off the console back access panel#1.

Take off the knob#20, then make down where all the wires connect to on the old timer, and re-connect them the same on the new timer.

Remove the timer mounting screws#9 and put in the new timer.

Make sure you unplug your dryer before doing any of this!

Jake, I replaced the timer and it is working on timed dry. My wife's only remarks are that the timer is louder (???) and that the sensor dry is not working. I think at one point we had a ventilation issue when the dryer was pushed against the wall but that has been cleared up.

Glad its working again on timed dry.

If auto-dry isn't working its likely the electronic control board is bad as well, don't know how much you want to spend on it, its about $112:
Manufacturer's Number: 8558178




But you use on timed forever if you don't want to put any more money into it, and it will still work fine.

on auto-dry it shuts off but the clothes are still damp. could it be something else?

also found this part used delivered for less than $10 if that is the problem. Gotta be worth a try with 90 warranty and free returns??
