Over-Freezing-Figure 17
•
Insure the capillary tube is properly attached to the
cooling fins (Capillary tube mislocation is a common
cause of over-freezing.). The capillary tube should
be against the fin, with the clips spaced approxi-
mately 5 inches apart.
•
Turn off gas supply to refrigerator.
•
Turn refrigerator off.
•
Remove control panel (see removal procedure).
•
Use a 3/16" allen wrench to remove the pressure tap
plug. Using a 1/8" NPT nipple, connect a U-tube
manometer to the exposed port.
•
Remove capillary tube from cooling fins.
•
Place a cup of ice water on the shelf nearest the
cooling fins and immerse the capillary tube into the
ice water.
•
Adjust the thermostat setting from high to low. The
gas pressure should modulate between .8" to 10.9"
water column and stop modulating when not adjust-
ing the thermostat.
•
If the gas pressure does not modulate between .8
inches to 10.9 inches, replace the combination con-
trol.
