TIFFIN MOTORHOMES –ALLEGRO® Chapter 13 ROUTINE MAINTENANCE
13-35
Depending on whether your particular motor home has a Domestic or a Norcold refrigerator, there are
some steps to be taken in winterizing the optional ice maker associated with that refrigerator. For each
refrigerator model, the proper steps to be taken are these:
Domestic Refrigerator Ice Maker (optional)
1. Shut off the water supply to the ice maker.
2. Place a shallow pan under the water solenoid valve.
3. Remove the inlet fitting to the ice-maker water solenoid valve. Then drain the water from the supply line.
4. Remove the plastic nut and water line from the outlet side of the water solenoid valve. Then drain the water
from that line. Note: Do not lose the metal insert from the plastic water line. One recommended way to secure
this insert is to place it into a “zip lock” bag, seal the bag, punch a small hole through the top of the bag above
the zip-lock, insert any type of “twist-tie” (i.e., paper-coated, flexible metal wire) fastener through the hole, and
then secure that bag to the outlet line for safekeeping.
5. Connect a source of compressed air (up to 20 psig, maximum) onto the inlet fitting of the water solenoid valve.
Apply AC power to the solenoid valve for forcing the icemaker mold assembly through several harvest cycles.
6. Remove the plastic cover from the mold assembly. The bail arm must be in the “down” (or “on”) position.
7. Start the harvest cycle with a flat-blade screwdriver inserted into the center of the small gear.
8. Turn the gear counterclockwise (CCW), when the hold switch closes, the mold assembly will continue to operate
through the harvest cycle. During the water-fill sequence of the harvest cycle, the compressed air will blow out
the water trapped in the solenoid valve.
9. Repeat the harvest cycle operation (i.e., steps 7 and 8) several times. Note: Damage to the solenoid valve can
occur if the AC power is applied for more than 20 seconds.
10. Reconnect and tighten the lines on the water solenoid valve. The metal insert must be installed in the plastic
water line going to the outlet side of the water solenoid. Leave the water supply turned “off” until temperatures
are above 0º F (-18º C).
11. Dry out the ice-maker mold assembly with a soft cloth. Place the bail arm in the “up” (“off’) position.
