I have a 110.66662500 dryer that is taking at least two full cycles to dry clothes. All vents are clear, good air pressure out of the rear of the dryer and house vent, it takes this long regardless if the vent is hooked up or not. The heating element, high limit thermo, and cycle thermo have been replaced with no change in drying time or temp. Any ideas?

I guess you are talking about the internal bias thermostat part # is 3387134. That usually controls the temps. If you did not replace that one, that is the one I recommmend. The other thing you might want to check is the idler pully. That idler pully wears down to nothing. It wears down so bad, all there is, is the metal shell. There should be a white round wheel. That is where the belt wraos around it. You need to pop up the top, and take the front off to inspect it. Tom ApplianceEducator.com

Does changing the temperature setting do anything?
Could be the thermostat's internal heater is on all the time.
You could try measuring the exhaust temperature. The thermostat should open at 155 and re-close at 130 degrees at high heat.
Did you check that the blower wheel was clean and tight on the motor shaft?
Could be it is stripped and is slipping.
Did you check the drum seals and other internal seals in the unit.
Check that the filter screen is not coated with fabric softener residue. |

Check that the filter screen is not coated with fabric softener residue. The screen is free of debris and residue. I have not checked the blower wheel but I can do that, there is no unusual operating noise coming from the motor or blower unit and the air flow from the rear vent is significant, there doesn't seem to be any restriction. I have not formally measured the temp of the air out but it doesn't seem to be close to 130-155 F just by feel. If I operate the dryer for a short time and open it the metal screen adjacent to the element is very hot to the touch.

The drum will not spin up to speed, and cause the air not to leave the dryer properly, causing the high limit thermostat to short cycle. That would make the dryer take to long to dry. To view the belt. Pull the lint screen out, and there will be to phillip head screws right there. Remove them, and then, there will be a clip under the top of the dryer about 2 inches from each end, that hold the top down. Get a putty knife and hit the clip, and pry up at the same time, and thetop will come up on that sdide, and do the same on the other side. Of course you are doing this with the power off. Then look inside the front up top on the right and left side, you will see a 5/16s screw, remove them on both sides. That will release the top, the grab the left side of the front, and pull up quick and a little hard, and that will release the bottom of the front on that side. Do the same on the other side, and then unhook the door latch molex plug, and then lay down on your stomach and view the idler pully. Tom ApplianceEducator.com
