Hello, I have a Kenmore 80 series gas dryer. Over time it was taking longer and longer to dry and eventually it just stopped heating completely. I checked resistance on all electrical sensors and the fuse and they all seem to check out Ok. I then noticed that there was no flame in the burner. I tested the resistance on the coils and they also seemed to be in the acceptable range. I saw that the coils may be bad even though they show the resistance so I replaced a pair of the coils after which the gas started to come out and the flame came on.
I tried using the dryer after replacing the coils but it didn't work. The flame seem to be weak, it would come on some times and other times it wouldn't. The igniter is always glowing red and seem to cycle correctly. I took out the drum and the front panel and turned on the dryer, I saw the igniter glowing then I assume the flame sensor switch then the coils clicked and a decent flame came out of the burner. The flame stayed on and steady. Not knowing what else to look for I put the drum and the front panel back on and turned the dryer on again to test. A weak flame came out and went out in 10 seconds or so. This pattern would continue to cycle. All above I did while vent was disconnected from the dryer and I previously cleaned the exhaust inside the dryer with a vacuum and there is no noticeable clogs. There is a good air stream coming out of the blower and the blower wheel seems intact.
Out of ideas I took out the exhaust air channel to make sure there were nothing clogging the airflow and it was clear. With the exhaust channel off I turned on the dryer and saw the same decent quality steady flame that I saw when the drum and front panel were off. When I put it back on the flame went back to weak disappearing pattern. Last thing I did was turning the dryer on fully assembled and opened the front door while it was on (spinning). I jumped the door switch for the dryer to stay on. Strangely, when I open the front door the flame stays on and is noticeably stronger. When I close the front door the flame goes out within a couple of seconds.
I am totally lost and would appreciate any suggestions. Thank you!
