PROBLEM
POSSIBLE CAUSE
ACTION
The motor, light or
any of the other
components do not
work.
Check power supply:
1. Is it plugged in?
2. Is the receptacle live?
3. Is the machine plugged into the proper voltage?
(Measure with voltmeter and compare to
specification on nameplate of machine.)
Problem is in the
machine.
Check the relay/contactor. The Giant
temperature control uses a relay/contactor to
control the power to the popper pan heat
elements. To check the relay/contactor, perform
the following operations:
1. To gain access to the relay/contactor, remove
the front switchplate by removing the six screws
on the sides of the switchplate.
2. Using a voltmeter, check the power to the relay
coil, that are the small terminals in the center.
3. With the popper switch on, at room
temperature, the temperature control should be
calling for heat and providing power to the
relay/contactor. If the coil reading is not 120
volts. (230 volts on 230V and 400V, 50Hz
machines) the problem is in the temperature
control.
4. If the coil reading is 120 volts, (230 volts on
230V and 400V machines) check the voltage
between the output terminal with wire #1 and the
output terminal with wire #3 from the kettle
support. If this does not have a reading of 208 or
240 volts, the relay/contactor is not functioning
and needs to be replaced.
Kettle will not
heat.
If machine has the
one-pop option.
Use the same procedure as above. Then check the
one-pop circuit.
1. With the power OFF. Check the one-pop
switch for continuity by pressing and holding it
down. Remove wires (mark wires for proper re-
installation) from switch and press and hold.
Using a multimeter, check for continuity from top
to bottom of switch. If no continuity, replace
switch.
2. Check the input (com) and output (no) on
timer/relay.
Thermocouple has
bad connections.
Check all connections.

Thermocouple is
bad. Should read 3-
5 ohms if good.
Replace thermocouple.
