b. the voltage which reaches the ECU is equal to the one shown on the plate (minimum 11 volts, maximum 14
volts) .
c. the connections have the proper polarity and are secure.
d. the condenser fan is not jammed or obstructed.
e. the refrigerating unit is not near a source of heat.
f. the in-line fuse mounted on the feeding line is not blown.
2. Heavy frost buildup can be caused by several factors:
1
Warm foods introduced into the freezer or fridge section.
2 Fridge door frequently opened and closed (especially in a high humidity environment).
3 Fridge door not properly aligned with fridge body as to affect the rubber seals ability to seal as designed.
4 Failure of the putty seal between the back wall of the fridge and the evaporator tube. Would need to be
examined and resealed with existing putty.
5 Certain foods, mainly leafy vegetables, have a tendency to cause ice to form faster due to their high moisture
content.
Note: If the ice builds up more than 1/8 inch on either side, it can interfere with the freezer door opening and
shutting properly and can cause the freezer door to pop loose and reduces the ability of the fridge to cool properly
and the fridge will need to be defrosted. It goes without saying, the fridge needs to defrost naturally by turning off
power and opening the door.

remove excess moisture from any food and/or food packaging.
