SOLUTION

PROBLEM

The cooling fans
are not running.

         or

The heaters are
not turning on.

(continued)

The display board
interconnect cable is
not properly plugged
into the power supply
board.

Be sure the cable is firmly
plugged in.

The fan motor or
heater is defective.

Check if the motor or heater is
defective by connecting it to an
alternate power supply. If it still
is not operating, replace the
motor or heater.

Listen to see if there is a clicking
sound when the stage or heater
pilot light turns on. If there is no
clicking sound, contact your
distributor to repair the control-
ler.

The controller is
defective.
