For Whirlpool Idler Pulley Wheel (Part Number: AP4372890)

For about six months my dryer had been making a rumbling noise when it started and then became quieter once running. I ignored it (probably a bad idea) until about a week ago when the drum would stop turning after running a while. It would start again and then stop after a while. I assume this is the motor on overload(??). I took apart and found that one of the drum support rollers was tight. I have cleaned and lubricated both rollers and they now spin freely and seem okay. My question is regarding the idler pulley wheel. With the belt off the drum this wheel is loose and floppy. When I pull up on the belt as though it is around drum it seems fine. Is that how it is supposed to be or should this be replaced? FYI, I am also replacing my blower wheel assembly as it is worn and spins freely.

ANSWER Hello Mike. You will need to replace the idler arm 6-3033630 and the idler wheel 6-3037050 on the unit based on the information you provided.
