(b) Check the function of the door closed switch.
3. Is the lint door or drawer completely closed?
(a) Close the lint door or drawer.
(b) Check the function of the lint door/drawer switch.
4. Has the transformer primary or secondary circuit breaker tripped?
(a) Reset circuit breaker.
(b) Determine why the circuit breaker tripped.
5. Have the motor thermal overloads tripped?
(a) Disconnect the mainn power supply.
(b) Press reset buttons on one or both of the motor overloads located in the rear control
panel.
6. Has the fire supression system been activated (if so equipped)?
(a) If you see or smell smoke within the drying cylinder, call the fire department and leave

To troubleshoot using the schematic, begin by measuring for 24VAC at wire one on the terminal
strip located in the front control panel (always measure between the wire and a neutral wire, not
ground). Refer to figure 5.4 on page 32 and follow the path from wire 1 to wire 7. Where the
voltage is lost will indicate the problem component. For example, if you have voltage on wire 3
but not wire 5, there is a problem with the motor overloads or associated wiring.
Microprocessor Models
Refer to the Programming and Operation manual for the microprocessor for a complete list of error
messages and remedies. Typically, the error messages displayed will lead directly to a solution to
the problem.
