"Sassy999", I'm not going to shoot you with 64 questions, you seem to be headed in the right direction. "Vent Plaster" could be a cause of what you are describing as wrong with you dryer, the same thing "PoleCat" is talking about. This is when moist lint builds up within the venting within the dryer itself. One coating every now and then, and before too long you have a reduced venting system. This leads to "as not as much air moving as the day it was new" syndrome. YOU will NOT be able to tell the reduced air flow without some special instrumentation. Please do check every single inch of the internal ducting of you dryer. Another possibility, and I'll admit it's rare: The "over-temp" switch within your dryer could be going bad. This would create a situation where your heating element would actually go "ON and OFF" during the drying cycle. You will not notice it and the air would be "warm" as it comes out of the venting, but not warm enough/or enough flow to properly remove moisture. Another cause of this could be, but now always, a heating element which will heat but not properly (weak element). This does happen at times.
what you have is an obstruction in the dryers venting. You will have to completely disassemble the dryer, remove the drum, disassemble the blower housing and clean all the lint out. It is also a strong possibility that the blower wheel is just spinning on the motor shaft and that is why you have no air movement, this is a very common problem on Maytag dryers. If the wheel is bad replace it. Since you ran it for an extended period of time in this condition you probably blew the thermal fuse, that is why you now have no heat. Check the thermal fuse with an ohmmeter( it will be a round disk located on top the heating element), replace if necessary. Reassemble and you should be set. If you do not have basic tools or good diy skills, call a repairman.
