Whirlpool dryer not exhausting air, and the drum is spinning counter-clock wise

Hello. first of all the dryer drum is supposed to spin counter clockwise.

if you are not exhausting air you have to pull the dryer out from the wall, remove the vent pipe and thoroughly inspect both the pipe and the innerards of the dryer for lint blockage. if you have a long vent pipe and can't see the entire length slide a dry garden hose through it after you remove the vent pipe cover on the out side.

Hi,

The first and most important thing you need to do, is to disconnect the dryer from the wall outlet before doing any kind of work on it. Most parts will need to be checked for continuity and the dryer must be disconnected from the wall outlet.
Most of the times the part causing the problem is behind the dryer and you can gain access by removing the back panel.
