This is an old GE dryer. I need to know if the idler/torsion/tensioner pulley is a WE12X81 or WE12X83 - is there a difference between these?
The part number for the idler pulley for your model is WE12X83 although there does not appear to be any significant differences between the 2 pulleys.
Can idlerpulley #WE12X83 be changed from back of dryer?
Answer Hello Barry. No, you must go through the front of the dryer.
How can I get tensioning spring for idler arm.
There is not a tension spring for the idler pulley. The way that the arm is set up it is not required.
