 Test points L & N will verify 220 Volts to Ice Maker module. (Make sure your test probes go
into the test points ½")
 Test points T & H will verify if the bimetal thermostat is open or closed. Short T & H with an
insulated piece of wire (14 ga.) to run the motor. If the motor doesn't run, replace the module
assembly. If the motor runs, replace the bimetal thermostat.
 If you leave the jumper in for a half of a revolution, you can feel the heater in the moid heat up
if it's good. Remove the jumper and the water valve will be energized in the last half of the
revolution. (Make sure that the freezer temperature is cold enough to close the bimetal)
 Test points L & H will check the resistance of the heater (300 ohm). Replace the mold and
heater assembly if not near this value (+ or – 10 ohms) (Ejector blades should be at the end
of the cycle position)
 Test points L & M will check the resistance of the motor (about 21500 ohms).
Replace module assembly if not near this value (+ or – 10 ohms). (Module must be separated
from heater before testing).
