REPLACE
Replace the evaporator liquid solenoid valve coil as follows:
NOTE
There are two liquid solenoid valves; one in each compartments evaporator. This
procedure is applicable to the replacement of either liquid solenoid valve coil.
The liquid solenoid valve coil can be replaced without having to pump the
refrigeration unit down.
1. Open applicable evaporator cover panel (Figure 1, Item 1) by removing two bolts (Figure 1, Item 2) and two
washers (Figure 1, Item 3).
NOTE
The use of a step aid may be required during the performance of this task.
2. Tag and disconnect electrical connector (Figure 1, Item 4) from liquid solenoid valve coil (Figure 1, Item 5).
NOTE
During the removal of the retainer clip that secures the coil to the solenoid valve, the
use of a screwdriver may be required as a prying device to free the clip from the
enclosure tube.
3. Lift coil retainer clip (Figure 1, Item 6) securing coil (Figure 1, Item 5) to liquid solenoid valve (Figure 1, Item 8).
Retain retainer for installation of new coil.
4. Remove coil (Figure 1, Item 5) from liquid solenoid valve enclosing tube assembly (Figure 1, Item 7).
CAUTION
It is important that the replacement coil be of the same type, voltage rating, and
frequency of the coil that was removed. Coil type, voltage rating, and frequency
information are indicated on the coil housing. Make sure to verify this information
before installing the replacement coil or damage to the system may occur.
5. Verify coil type, voltage, and frequency of replacement coil nameplate is same as removed coil.
