TROUBLESHOOTING
LONG POPPING CYCLES
If your pop cycle is longer than 4 minutes, it can be the result of several things:
A. LOW VOLTAGE - If the machine is operated on low voltage, this could cause the kettle not to reach
the proper operating temperature. Voltage for each leg, with kettle turned on, must be at least 110v.
B. INADEQUATE SUPPLY LINES - Inadequately sized electrical supply lines, in addition to being a fire
hazard, would also prevent the kettle from reaching the proper operating temperature. Check with a
qualified electrician.
C. INFERIOR CORN - Inferior quality corn would result in longer popping cycles. Use only top quality
hybrid popcorn from reputable suppliers. Even then, if you let your corn pick up moisture or dry out,
your popping cycles will be slow.
KETTLE DOES NOT HEAT
Before you go any further, make sure the kettle lead-in cord is plugged in, and the kettle shunt trip
breaker is not tripped. (See Motor Plate Assy. Figure 4, Item 4.11) The shunt trip breaker may trip during
transit, if the machine has been handled in a rough manner. If the breaker is re-set - then trips again -
contact a service technician for inspection/repair before going further.
A. KETTLE HEAT SWITCH - Check the voltage to and from the “KETTLE HEAT” switch, and if the
switch is defective replace it.
B. CONTROL - A defective thermocouple lead will cause the kettle not to heat. Check for good
connections from the kettle to the control.
C. MAIN RELAY. (See Motor Plate Assy. Figure 4, Item 4.6)
MOTOR WILL NOT TURN AGITATOR
WARNING! If the kettle agitator shaft is not rotating, DO NOT pop corn. Adjust the clearance
between the kettle bottom and the stir blade to 1/32” (use a dime). Loosen the set screw in the collars
above and below the crossbar and adjust the agitator shaft as necessary. Then re-tighten the set screws
in the collars.
OIL PUMP DOES NOT DELIVER OIL TO KETTLE
If the pump is operating but oil is not dispensed, the oil may be solid in the oil lines.
If the pump is not operating at all, see the pump manual for instructions.
