Before ordering:
-
Confirm your dryer’s model number and serial number (typically inside the door frame or on the back panel).
-
Remove the access panel and verify your current idler pulley matches the part: same diameter, same mounting bracket, same bearing style.
-
If the dryer has worn drum rollers, a stretched belt or mis-aligned drum, replacing the idler pulley may not solve all rotation issues — a technician evaluation may be required.
