Turned the dryer on and started making a loud "rumbling" noise while the drum was rotating.
Replaced rear drum support. Ran dryer after replacement and seemed fine.
New belt also and restrung the heating element coil (per request).
Got a call back saying dryer has the same "rumbling" noise and "LOC" is on the display and dryer will not start.
To clear the "LOC", press Options and Select at the same time and hold for 10 seconds.
Anyone with a suggestion as to what else would cause the drum to "rumble" and cause a "LOC" to show up on control board.
