We replaced the heating element and that is not the problem. Good airflow coming out back of dryer,vent hose and lint traps are clear, and coils heating up. Help! What else could be the problem?

I will venture a guess that's it's a stackable unit, one with the washer on the bottom with a dryer on top of the washer, a one piece unit. Am I correct? If so, it probably runs on 110V not the usual 220V and those dryers take much longer to dry normally.

No, its not a stackable and was working fine up until about 6 weeks ago.

Let's see if a trained appliance tech has a solution or idea. I am stumped.

Have you check where vent hose exits house. Many times it get clogged there or birds will build a nest there. I does sound a lot like a venting problem. Also check to be sure the flexable vent is not pinched anywhere. One easy test for this would be to disconnect vent hose from back of dryer and run a load. Doest it dry in less time? If yes, Problem is venting. I know you said it is all clear but double check it. Also , confirm there is 220V at the outlet and not 110

Also,if the door seal can wear out and leak, which can disrupt proper air flow. Check the area where the blower motor is. Is it all free of lint. What model is this?

It's a Maytag LDE490

I will remove the vent hose and run a load and see what happens... The dryer is in the basement and the vent hose runs into the wall and I assume it filters outside. I did find a opening on the outside of the house, but could not feel any air coming out of it. (but it is quite a distance away from the actual dryer). I will try the above today and report my findings! I will also check out the door seal.

Thank you!

If dryer is running and no air is exit at the outside you have found the problem. The solution is to find he restriction. It will be somewhere between the dryer and out side. You may have to remove the cover on outside of house only to find it clogged there. Good luck. Post back with results as it may help others.

There is no cover on the outside of the house, which concerns me about critters and things climbing in. But will still run a load w/o the vent hose to make sure.

I'd say you found your problem. You need to get a dryer cover for it. Critters do like to get in there. Also birds love to build nest. Seen it many times

Well, I took the vent off and a load dried in a normal cycle. So there is a blockage somewhere between the wall and the outside of the house. This is no easy task as I'm not sure where the vent is (as the vent from the dryer goes into a wall - strange design) and you can't see where the tubing starts in the wall that eventually leads outside. I expect the tubing is at least 15-20 feet long going from the basement to upstairs. I may have to call someone to clear it out.

Thanks for all the help :-).

Get it clean and you'll be set to go. Think how much extra your electric bill is with the dryer running twice as long. The fix will be paid for in no time at all. Glad I could help
