IV. Refrigeration Circuit and Component Service Information
WARNING
• This appliance should be diagnosed and repaired only by qualified service personnel
to reduce the risk of death, electric shock, serious injury, or fire.
•
To reduce the risk of electric shock, do not touch the control switch or plug with damp
hands. Make sure the control switch is in the "OFF" position before plugging in or
unplugging the appliance.
•
Move the control switch to the "OFF" position and unplug the appliance from the electrical
outlet before servicing.

in place after any maintenance is done to the appliance. Make sure that none have
fallen into the storage bin.
•
Make sure all food zones in the icemaker and storage bin are clean after service.
A. Refrigeration Circuit Service Information
WARNING
• Repairs requiring the refrigeration circuit to be opened must be performed by properly
trained and EPA-certified service personnel.
• Use an electronic leak detector or soap bubbles to check for leaks. Add a trace of
refrigerant to the system (if using an electronic leak detector), and then raise the pressure
using nitrogen gas (140 PSIG). Do not use R-134a as a mixture with pressurized air
for leak testing.
NOTICE
• Always recover the refrigerant and store it in an approved container. Do not discharge
the refrigerant into the atmosphere.
• Do not leave the system open for longer than 15 min. when replacing or servicing parts.
The Polyol Ester (POE) oils used in R-134a applications can absorb moisture quickly.
Therefore it is important to prevent moisture from entering the system when replacing
or servicing parts.
• Always install a new drier every time the sealed refrigeration system is opened. Do not
replace the drier until after all other repair or replacement has been made. Install the
new drier with the arrow on the drier in the direction of the refrigerant flow.
• When brazing, protect the drier by using a wet cloth to prevent the drier from overheating.
Do not allow the drier to exceed 250°F (121°C).
1. Refrigerant Recovery
No refrigerant access valves are provided on this appliance. Using proper refrigerant
practices, utilize a temporary tap-line valve on the high side to recover the refrigerant.
Store the refrigerant in an approved container. Do not discharge the refrigerant into
the atmosphere. After recovery is complete, replace the tap-line valve with a proper,
permanent access valve.
