Kenmore 70 Series "no heat"
« on: March 05, 2014, 04:17:57 PM »

Howdy and thanks for haveing me on this site. I know this will be beating a dead....dead horse, but here it goes. I have a 110.66722694 dryer. It has no heat. My wife has been complaining about it not drying for along time now. A couple of weeks ago we took the dryier apart as i had lost a key that i needed. Anyway we cleaned it out really good all the lint and everything. Was working fine but yesterday no heat. Still tumbles. I checked breakers, 240v at terminals on dryer. The thermal fuse, cycling thermostat, high limit thermostat, and heating element all had continuity under 0.4ohms. The thermal cutout read normal but move it around and reads 140ohms, so no good. I then jumped that cutout and nothing. So i eventually jumped all the switchs and still no heat. I am getting 120v at the heating element but no heat. Element reads about 9.0ohms. I am pretty sure i need 240v to heat the element. The 120v is coming from the red wire that runs underneath dryer. I also checked the timer switch. I took the large red wire off of terminal R, put my meter to that terminal and several others on the timer switch while turning the switch. I got "ol" throughout this test. I am no electrician or appliance man, but i am frazzelled. Any help would be greatly appreciated.

Check the timer, open it up and you'll probably find a contact burnt or not making up on the Red Wire contact. I just had one that had the same exact problem. Also there are plastic stop tabs inside the timer, check to see if one of the contacts are not fused or melted to the plastic tabs. Also while you have the timer apart place the knob on the timer shaft and rotate the timer knob and make sure each contact is making up. It should be a dead give away which contact is burn't or plastic tab melted. Also depending on what timer you have I've seen the plastic cam gears on the timer shaft actually slip down off the cam and just float you can re-attach them with crazy glue otherwise your looking at a new timer. Let me know what you find.

  With timer set to normal heat cycle, you should have continuity between terminals R and BK. If not timer is bad and should be replaced. To test only, disconnect black wire from BK terminal that goes to timer motor and connect the red wire there. Turn dryer on and it should work.
