CONVEYOR OVEN SERVICE MANUAL
TROUBLESHOOTING
Conveyor Not Moving
The conveyor motor is powered by the 24VDC power
supply through a 3 amp fuse. This fuse is designed to
limit the damage to the belt if an obstruction were to
enter the conveyor assembly. The motor is controlled
by the speed controller which uses an external
potentiometer to regulate the speed.
Due to the design of the electrical circuit, the unit
is never truly in an “Off Mode”. When the power
switch is set to “standby” , electricity is still
present in the control panel. Always disconnect
the power from the wall before opening the
control panel
