Why do the thermal fuses keep blowing on my Kenmore model 110.60884990 dryer?

Thanks LYLE W for your previous answer and here is some additional information that might be helpful. The hose is absolutely clear and it is only a few inches long and then it goes straight through an outside wall. There is a vent cover outside with a flap that seems to operate. It rattles when it is windy outside so it moves then. I clean the lint filter screen every drying operation, and don't dry my towels in it so there is no big lint items being dried.

I have had the dryer about 7 years and have replaced the fuse 3 maybe 4 times.

I stopped using the sensor to dryness feature after the first blown fuse and only use timed drying now.

I am hoping this extra info might cut down on the possible problems you mentioned.

Repeated thermal fuse problems can be difficult to pin down. You mentioned the usual suspect the vent is clear and not restricted.

There are a couple of things to consider. It shouldn't make any difference if you’re running an automatic cycle or timed cycle to the thermal fuse.

Unplug the dryer and remove the rear panel. With the rear panel removed you can turn the timer on to a heat cycle but don't start the dryer. See if the element gets hot with the timer turned on but the motor not running. A grounded element can come on with the timer turned on even though the motor is not running. It will heat with 120 volts so it may not be as hot or bright as normal but it can still get hot enough with no air flow to open the thermal fuse.

There is one other potential cause of the thermal fuse blowing repeatedly.

Lyle covered the basic things like air flow and these are the normal causes of a blown thermal fuse.

If the vent is okay and the temperatures are correct then the other thing that might cause this problem is how the clothes are checked to see if they are dry.

One potential problem is how the clothes are being checked to see if they’re dry.

Towards the end of a cycle sometimes a customer will simply open the dryer door and put their hand in to see if the clothes are dry. If they're not dry you close the door and hit start again.

The proper way to check the load is to turn the dryer off before opening the door. When you open the door with the dryer still running and heating then as soon as you open the door you lose the airflow. The element will continue to heat until the motor stops turning. This extra time with the element on but the door open and no airflow is enough to blow the thermal fuse.

If you have been doing this then in the future turn the dryer off first and then open the door and check if the load if dry.

I hope this information helps resolve this problem but submit another question with any additional details for further assistance if the problem happens again.
