Dryers heat shuts off after 5 minutes

Brand: Kenmore
Model Number: 110.61202011
Main Symptom: Heat stops shortly after starting
What happens & when: When starting a timed/humidity run cycle, irresepctive of heat setting, the heat will start and run for about 5 minutes, before eventually stopping and continues running with air only.

I have tested the fuse, thermal cutoff, heater core, and anything else I can pull the terminal off and tested for continuity and ground loop. When testing the heater core, it tests good for contuinity, with no grounds, and measures at 9.9 ohms with my multimeter. Inspecting the heating element shows it mildly discolored, but I can’t see/feel anything loose.

I’m tempted to buy a heating element and thermal cut off, but would like anyone’s opinion if I should replace more, or less, or do more diags. I have the electric dryer in the appliance parts pros youtube video below.

jump between C and A on timer. and then run it for awhile with this timer they are junky.Contacts in timer could be falling under a load.

Idk if I didn’t have enough contact but I got some arcing on the bridge, so I disconnected that afterwards. I noticed its more likely to heat on the auto-sending vs the timed dry, so I’m going to get the timer and heating element, since the heating element isn’t that expensive it’ll just be for peace of mind and hopefully this dryer last another 15 years.

Hey Colby, did you ever figure out what was causing the heating issue with your dryer? Have you tried running it on each timer setting? And when the timer gets to the end of the cycle, does it shut off like it’s supposed to, or does it just keep running without cutting off?

I did not, but it does shut off after the end of both timed and sensor drying cycles. The moisture sensor settings shut off with it still being wet, I’m wondering if there’s some limit set on the timer that after X time it shuts off whether the sensor has triggered or not.

I would check the airflow between the dryer and the vent to make sure there are no clogs or restrictions. Take the vent off and run the dryer to see if the issue improves. If that doesn’t solve the problem, I’d consider replacing the high-limit thermostat and thermal cutoff before moving on to the timer.

Use a multimeter to check power to the element, if you have 240VAC to the element and it is not heating the element is bad. If you do not have power to the element then the issue is a thermostat or control.

Although I don’t have the same dryer mine was doing this same thing. The heat was shutting off and the clothes never dried. I checked everything because not long before that I put a new coil.belt and whole roller support system. The air flow was not blocked but in the end I pulled the exhaust hose and checked the 6 ft of metal duct. The metal duct was partially blocked. Not enough to stop the air flow but enough to limit it so the dryer overheated and the High limit was triggered, causing the heating coil shut down. I cleaned out the ductwork and I then realized how much more exhaust flow it had. That was the whole problem. It’s been fine since
