E. If the Fan Blade/Blower Wheel is not dragging on the Element Cover or the Proofer floor and
the Proofer Motor spins easily by hand but still does not run:
1. Check all electrical connections between the Power Switch and the Proofer Motor. All
connections must be clean and tight.
NOTE: It may be necessary to remove the Proofer Motor Assembly for electrical
inspection.
2. Check for voltage from the Power Switch to the Proofer Motor. If voltage is present but
the Motor does not run it must be replaced (refer to PROOFER MOTOR ASSEMBLY,
How to Replace in the SERVICE AND REPLACEMENT GUIDE).
V. The Proofer Timer [36] does not run:
A. Check the electrical connections between the Proofer Power Switch [31] and the Proofer
Timer. All connections must be clean and tight.
B. Make sure that the Timer wiring is correct. The black wire from the Power Switch is
connected to terminal "4" on back of the Timer. Terminal "6" on back of the Timer is
connected to one side of the Proofer Buzzer Alarm [16].
C. Turn the Timer Knob back and forth several times to free it from any possible sticking.
D. If the Timer still does not run, or runs only after the Knob has been turned back and forth
several times, the Timer must be replaced (refer to TIMER, How to Replace in the SERVICE
AND REPLACEMENT GUIDE).
VI. The Buzzer Alarm [16] does not sound:
A. Check the Proofer Timer [36] for proper operation.
B. Make sure the Buzzer Alarm wiring is correct. One side of the Buzzer Alarm is connected to
terminal "6" on back of the Timer. The other side of the Buzzer Alarm is connected to any
common or group of common (WHITE) wires.
C. If all connections are correct, clean and tight and the Buzzer still does not operate it must be
replaced (refer to BUZZER ALARM, How to Replace in the SERVICE AND
REPLACEMENT GUIDE).
VII. One or more Indicator Lights do not function:
An Indicator Light tells when a System or Control is activated. Failure of the Indicator Light itself
will not affect the over-all operation of your unit.
A. Make sure all electrical connections are clean and tight.
B. Check the associated Control to see if it functions correctly. If the Control functions but the
Light does not go on the Light itself is bad and should be replaced (refer to INDICATOR
LIGHT, How to Replace in the SERVICE AND REPLACEMENT GUIDE).
