Modular
Resistance Checking of Components
The icemaker components can also be resistance checked through the front of the
module.
Inserting the ohmmeter leads between test points L and H will check the resistance of
the heater (72 ohms, ± 10%)
Inserting the leads between L and M will check the motor resistance (approximately
4400 ohms)
Test points V and N will check the resistance of the water valve coil (approximately
300 ohms). This check is especially helpful since it allows you to check the continuity
of the water valve without having to pull the refrigerator away from the wall.
The refrigerator must be unplugged from source voltage before any resistance read-
ings can be attempted. A resistance check can be performed on all components from
the front of the module
