I am not fully acquainted with this model but I have seen this problem from time to time on other models. An item you should check is the temp thermostat. Replace it and evaluate. This thermostat is on the burner tube and is a 2 connector type device. It is easy to access and not very expensive.

You are welcome. I'm glad you were able to fix it. The conclusion you made about vent cleaning is absolutely right. Unfortunately most of people do not pay attention to it.

Got the vent cleared. I was really surprised how much junk could be in there. When I was running just the drain snake up the stack and reached the clog, it was coiling up and making a u turn and springing back out the duct. Since I could not climb on the roof due to a tile roof, I came up with a solution of buying a simple 10 foot RV garden hose and ran the drain snake thru the hose and then up the stack. This kept the snake straight and was able to grab the lint and pull it down.
Worked beautifully. Now with it cleared, I was able to run a 10 ft long vent dryer brush up and get the rest along the duct sides. A cheap means of doing it. Now every 4 to 6 months, I'll run the long bottle brush type made for cleaning these stacks to keep it clear.
Thanks for the help.

The best solution in such situation is to hire a pro in vent cleaning because they have some special equipment to better handle it. Such service usually cost about $100 and it's worth that money.

Had to use another ID because this one won't let me on either. Same jmrec100 and japp111.
I ran a whole bunch of times at Low, med and high with vent hose only, no vent attached and then the vent hose completely hooked up. When I connected the vent hose to the outside vent, the times went really long, especially on low. So something is plugged up. Suspect a bird's nest? Or clogged lint or maybe an animal? I hope not. I'm going to run a drain snake up the vent and see if I hook some junk. I had used a refrigerator brush before and reach up about 4 feet and it was clear. So I thought it was clear to the top. Guess not. It's a tile roof so I can't stand on it. I'll climb up a ladder as far as I can to see if I can see if something went over the outlet. Then I'll access it thru the attic and cut a hole or cut open the vent pipe and run a brush up and down it. Bought a 4" connector for ducting and will use it with duct tape to seal it back up. I'll post what I find.

These timings are perfect and it shows there is something wrong with the hose and the vent. Try to run a load with no vent hose connected. Gene.

Hi Gene, I'm back with the same problem. Couldn't log into the site to post for some reason. Keep getting an error 20 or something and the help guys really didn't have an answer. Created this account. A continuation of jmrec100. Anyway, here goes.
Been living with LONG drying times. Requires 3 cycles of a setting of 70 each to dry pants. used to take at most one cycle. But I have to fix it. Last time, I found a broken Flame sensor. Replaced that and it is operating the flame now.
But takes forever to dry. I have taken the dryer vent chutes apart, checked the vent hose, the stack (Ran a brush up the stack and its clear) and it still takes forever to dry. I took some numbers and times for the flame on and off at the high dry setting. I will post it shortly. Putting it together in a readable fashion.
I am going to run a very long wire up to the roof where the stack is and check even further. As a last resort, I may cut open the stack in the attic to be sure. Can't access it on a tile roof.
