Need Appliance Repair Help? Ask a Technician for Answers ASAP
Ooops! I guess that would help. Kenmore model 110.96468100. My mother-in-law says sometimes she can feel the heat and other times she can't. Very intermittent. If it was a timer I was thinking it would be a consistent heat/no heat situation with each cycle.
Dry times are a bit longer. Feels the heat in the drum. She bought a new dryer today and I'm inheriting this unit. I'm going to repair it and give it to my son and his buddies for their apartment. College kids...
Great idea! Well, elements and thermostats are not usually intermittent, nor are timers. I would look at the seal in the rear of the drum and the seal at the front of the drum. The air needs to follow the intended path or the element will get hot and shut down prematurely. I suspect an air flow issue, so while you have it accessible, remove the back and just to the left of the place where the air comes out, you will see the bottom of the lint filter housing, shown as number 55 in the diagram below. There are four 5/16" screws that hold that tight to the bulkhead. Remove those screws and gently pull the bottom out so you are able to see in there. I suspect it may be plugged. Clean it out as well as the rest of that area and you will probably have remedied the issue. You may want to check your mom's vent line, too. If it is plugged, she may experience the same thing with the new dryer.
Please let me know if you have additional questions or need clarification. There is no additional charge for any follow up help!
Thank you for allowing me to assist you! I am happy to answer any follow up questions you may have atno additional charge.
Thank you for a positive feedback rating!
Ummm, yeah I forgot about air flow. Fire hazard too if stuff is in there. I intend to replace the belt since I'm there anyway. If I need to check the thermal cut off and high limit thermostat what kind of resistance readings should I get when I check with my meter?
Makes sense. If I pull the wires and have no power to the dryer then there should be no resistance. If I did have resistance with the above items then I would have a bad sensor. Right?
Thanks. I'll be driving Saturday to pick it up and bring it home. 150 mile round trip. I might have to repair it at my son's apartment since I have no way of hooking it up for power here at my place. Already have one in place here and no space to have two in the same room.
Sure, every little bit helps.
Thanks, XXXXX XXXXX Appreciate the help.

I'm back. I pulled the panel off and there is minimal lint in the lint chamber. There is no heat in any cycle. I get no voltage to the heating element when running in any cycle. With no power I checked the ohms and got this: Upper cut off at the top of the element box=0.2. The lower thermostat in the element box=0.2. The element had 9.9 to 10. The 4 wire block had 7 between the purple wire terminals and 0.1 to 0.2 between the red wire terminals. The two terminal block to the left of the 4 wire terminal had 0.2. I listened to the timer and I don't hear the typical mechanical tick, tick, tick. Timer?
Yes. I did check at the terminal block. 240 volts on the outside terminals and 120 from the middle to the right and middle to the left.
33 volts with the H2 wire removed and 25 with the H1 wire removed. Hard to tell what goes where so I tested both.
Is that making sense? No 120 volts.
32 volts from each terminal and grounded to the cabinet with the motor running and in the timed cycle.
120 from the center to each outer.
Yep, about 240 on the outer. Correction on the previous stuff. I initially grounded to the cabinet. So, I grounded to the ground which pops out from the terminal block and where you can take a small wire and ground to the receptacle screw. Still 240 on the outer terminals and 120 from center to each outside terminal. I read 120 to the H1 wire on the element, but not the other wire.
Oh, the 120 voltage was with the motor not running.
I unplugged each of the wires from the element one at a time. With the motor running I could get 120 volts from each of the element terminals.
0.33 with motor running and .05 with motor not running.
1 volt plugged in and not running. 0.7 volt plugged in and running.
I presume the contact should have read 120 with the wire off?
Still can't send photos on this site, that's been out for several months. I opened it up and one of the contacts is scorched and totally missing. Bad boy even arced when I was testing.
Thanks for the assist.
Just thought you might like to see what I found when I popped the timer cover off. Pretty ugly. I can't attach a photo due to problems with the site, but I can send this link to my Dropbox account which they tell us to use as a workaround for now.
Just wanted you to know I've replaced the timer and all is well. All I have left is to take the shop vac and clean out the lint and replace the belt as preventive maintenance. Thanks again for the help.
Thought you might like to see this. Finished the dryer this Saturday and basically tore it down to its components. Changed the belt (major deterioration with cracks) and pulled the chamber out (no easy feat since I had to remove the top and some extra screws from the drum support in the rear). It was easier see this once I removed it and I couldn't clean it any other way. The motor was pretty bad too. Had to be careful at the motor since I think these things still have capacitors? Touch the wrong contacts and it will light you up. I used a reefer coil cleaning brush, but since it has a metal shaft I knew to be careful about the contacts. Should have had a paint brush to dust it off instead. Good Sears shop vac helped.

OK, I feel so inadequate. Yours is much better. Can we say "fire hazard"?
Kelly, a follow up question. My son says it still takes a while to dry clothes in this dryer. Is this model prone to take a while due to its small size or is there anything else I should check?
Hard to say, since it's in an apartment. There was a panel on the wall they had attached with screws to cover it, but it only went up the wall for a couple of feet. It must vent upward to the attic and through the roof possibly. My son says he doesn't see a vent on the wall.
Thanks, I'll have him work on it.
Just a little follow-up on this issue. Dryer vent at the apartment was blocked. It still takes a bit of time to dry things, but I think this is a relatively small dryer and my son and his buddies would overload it. I would like to open another question to you about the washer now. How do I proceed?
