TUMBLER SUPPORT
WHEEL ASSEMBLY REPLACEMENT:
The front wheel assemblies can be replaced with
the lower front panel removed. Remove the three
bolts by reaching upward with a socket or box
wrench. The illustration below is provided to show
the location of these wheels as the wheels cannot
easily be seen while standing in front of the dryer.
The left rear wheel assembly can be removed with
just the back guard removed. The rear right wheel
requires removing the back guard, heat duct, and
oven. Be sure to mark the position of rear wheel
brackets prior to removal (refer to page 7).
All wheel assemblies are mounted on slots to allow
for alignment of the tumbler. After one or more wheel
assemblies are replaced, the tumbler must be
realigned.
