Problem - Cabinet Will Not Heat
QUESTION: Do any of the other components work - blower, light, etc?
NO! Check power supply:
A. Is it plugged in?
B. Is the receptacle live?
C. Is machine plugged into the proper voltage? Measure with voltmeter and compare
to specification on nameplate of machine.
Do not attempt electrical repairs on the power supply circuit unless you are
qualified to do so. The electrical shock associated with line voltages can cause
serious injury or death.
YES!
If the temperature controller is on, but the blower is not running and there is no heat,
check the high limit by performing the following operation;
a) Unplug machine.
b) Remove Heat Box (see Sanitation Instruction section for removal)
c) Locate High Limit Switch.
a. Press the red button in the center of the high limit thermostat to reset.
b. Using a multimeter, check the continuity between the two terminals on
the high limit, but first remove the wires from the terminals. If the
reading is 0 the high limit is good. If it is does not measure 0 try
pressing the red reset button one more time and repeat test. If the reading
is still not 0 replace the high limit.
d) Using multimeter, check continuity of the heat element. Remove the wire from
one terminal. The meter should read 13 for 120-volt machine. If reading does
not match, replace the heat element.
If the blower is running but there is no heating, perform the following operation;
a) With the heat box removed using a multimeter check the resistance reading on
the heating element. First remove the wires on the terminals.
b) Reading should be 13 for a 120 volt machine. If the reading is 13 the element
is good and the temperature control will need to be checked and replaced. If the
reading is not 13 the heating element will need replacement.
