Pressure Regulator Removal
To replace the ice maker pressure regulator:
1. Disconnect refrigerator from electrical supply.
2. Remove freezer door, baskets and evaporator
cover.
4. Disconnect defrost heater and push it down out of
your way.
5. Cut ice maker suction line going into and out of the
regulator at line weld and remove regulator.
(See Figure 7-16 )
6. Clean both ends in suction line.
7. Place heat shield in freezer behind lines that were
connected to the cut out regulator. (See Figure 7-17)
8. Install the jumper tube in place of the regulator.
9. Weld the inlet and outlet lines to the jumper tube.
10. Replace filter-drier using caution to connect cap
tubes properly.
11. Evacuate and recharge system.
12. Run product to make sure refrigerant is circulating.
13. Reinstall evaporator and compartment covers.
Replace freezer baskets and door.
The regulator is no longer used in production. If it
fails in the field, it is to be replaced with a jumper
tube Part# 242036701 to connect ice maker suction
line to line going to accumulator on the evaporator.

5. Cut condenser outlet tube at filter-drier. Discard
filter-drier.
6. Thoroughly clean condenser outlet tube and
capillary tube.
7. Place inlet connection of filter-drier over condenser
tube approximately ¼” and solder.
8. Insert capillary tubes input end into filter-drier
