 No Hot Air Brand: Whirlpool Model Number: LEN3634DW1 Age: 5 - 10 years
No Hot Air
What my dryer does:
Goes through the complete drying cyclye (Like there was no problem.)
Timer runs, the unit tumbles with no apparant problems
What I have done:
I took apart both the heating (Noticed some burning around the elements walls.)
and cooling sections and completely cleaned them. I then cleaned and visually checked all connections. They looked good. I did not test any components or connections electrically.
After reading some of the other posts I think I should:
Check the thermal fuse?
Check the element?
Other item of note:
When I was checking out the tumble section of the dryer I noticed what appeared to be some burn marks around the air holes that the hot air enters the chamber through. |
