Kenmore Dryer 110.66722694

14 posts in this topic

My Series 70 Kenmore dryer has literally over night decided to stop co-operating. In either Auto-Dry or Timed Dry modes it will not turn off. I have made sure that the vent filter and vent tube are clear and clean. I have replaced the timer and get the same results. The dryer heats up and will dry the clothes, yet the timer never moves from where it was set when the dryer was turned on. Any help would be appreciated.

the timer motor wont move or get energy until the moister sensor stops detecting dampness in the clothes

if you look on the back bulkhead inside the machine you will see the moisture sensors right there a black thingie with two metal stripes  as the clothes rub against this they make resistance contact if they are damp . when it detects no more damp then it energizes the timer and then the thang shuts off.

Is true the timer will not advance in auto if the heat circuit is not doing its thing, but should advance in timed dry no matter what the heat circuit is doing, let me see what is in your dryer...be back in a bit...110.66722694

Ok, this looks to take the 3976577 timer which has the 240 volt timer motor, did you order the right one???

Hmm... thought I did. The new one looks exactly like the old one. Will have to check it tonight when I get home. One of my co-workers suggested at lunch that the resistor could be bad? I'm not an electrician, so might he have a legit thought process?

You are correct, a resister on or attached to the timer has to do with the timer advancing in automatic, does not come into play in timed dry....however I do not see a resister attached to the timer in the breakdown for your model number which would make sense because the dryers with the 240 volt timer motors do not have resisters, this 240 volt timer motor was implimented to take the place of the resister...but is odd the new timer is doing the same thing as the old one..are we sure there is 240 volts to the dryer???

I'm sure there is 220. I use the same outlet for my air compressor when I need it and I checked to make sure the air compressor worked when the dryer started acting up Sunday night. Would I need an electrician to check for 240 or can I safely do it with a volt meter?

Yes, I saw that reference # 37, however there is no resister on the timer itself to advance the timer in auto if it has the 250 volt timer motor which it shows this model number to have??  Since this is a Whirlpool dryer with the Kenmore model number cannot compare it against the ones listed in this SERVICE POINTER from Whirlpool adressing this change....look on your timer when you get home and see what voltage is stated.

yeah that was what that resister was for to keep the dang timer motor from being torched . how do I know this? I have fried a timer by jumping out that resister .bad idea

Okay, I compared the 2 timers and they have identical information on them as follows: Model M460-G, 1/3hp, 15/7.5A, 125/250VAC. I also checked the outlet and it pegged my volt meter at 240 volts. I did notice 2 things tonight; 1) the plastic on one of the female recepticles on the outlet appeared to be partially melted, the plastic was definitely discolored and 2) the paint on the dryer where the resistor sits on the metal surface was brown  and the clear plastic "sleeve" the the resistor sits in was burned where it touches the metal surface of the dryer. Might either of these be causing my problems?

Thanks.

you are supposed to change the resister when you put the new timer on and the resister is a seperate part

Got a new resistor and installed it on Saturday, dryer works like new. Sunday, just for the heck of it, I reinstalled the old timer and it worked also! Would not have thought that the resistor would have been the only reason for the issues, but looks like it was.

 

Thanks fo rthe help.
