Original problem: Blower fan came loose from the motor shaft.belt and was making a noise clothes were slow drying. Second problem appear upon inspection: idler pulley bracket shaft severely worn.

Replacing the blower fan took way too long, like 4 hrs, because I didn't know how to disassemble the dryer and get to the problem. Replacing the idler bracket and assorted retaining rings and washers was fast, something like 1 hour. Disconnect the power cord, exhaust hose, and gas line. Remove two screws at the bottom of the face of the machine, unplug the electrical harness to the door light, switch and ground and remove the front of the machine. Remove the access panel at the back of the machine and remove the belt from the idler pulley. Remove the four screws holding the front drum support assembly and remove the drum. Replace some old retaining rings and the spring washers on the drum support rollers. Around back assemble the idler pulley assembly with some new washers and the old roller which seemed in good condition. Put it all back together. About one hour.
