Mold Heater Resistance Check; Checking Voltage At Motor Terminals; Winterizing The Ice Maker Water - Norcold N61X Service Manual

Mold Heater Resistance Check

Unplug the ice maker AC power cord before taking any
resistance readings on the ice maker.
To contact test points L and H, the test probes must
be at least 1/2 inch long. Connect the multimeter's
probes as shown in Figure 56.
n
Resistance values: 71 to 79 Ω.
n
Replace the ice maker if the mold heater
resistance is not within 71 and 79 Ω.

Checking Voltage at Motor Terminals

Make sure AC power is available to the ice maker
before taking voltage readings across test points N
and M.
To contact test points N and M, the test probes must
be at least 1/2 inch long. Figure 57 shows the
multimeter connections to points N and M to measure
voltage. The voltage across points L and M should be
108 to 132 Vac. If no voltage is detected, make sure
replace the ice maker.

Winterizing the Ice Maker Water

To winterize the ice maker:
1. Shut off the RV water supply to the ice maker.
2. Lower the ice maker shut-off arm to the off position.
3. Disconnect the garden hose adapter from the water
valve.
4. Disconnect the ice maker water supply line from the
water valve. Do not unwrap the water line heater wire
from the water valve outlet connection.
.
5. Allow the water to drain from the RV water supply line
and the ice maker water line.
6. Protect connections by bagging and taping RV water
supply connection, the ice maker water line connection,
and the water valve connections
