To properly test a Cooling Unit
Three criteria have to be met:
•Level ?
•Ventilation ?
•Heat Source?
Ventilation
Make sure you check Ventilation and Air Flow
-0” clearance on the sides and top
-No more than 1” from back of CU to
sidewall. (A baffle may need to be installed to
help direct air across coils)
-If there is an auxiliary fan, check that it is
working properly.

Symptom: Not Cooling
Air is not being forced through the
condenser – to much space!
Warm air is being trapped around
the refrigerator from a poor
installation.
AUXILIARY FANS
Helps with air flow.

Heating Elements
The function of the heating element
is to provide the boiler with a
specific amount of BTU’s of Heat
AC Heating Element 6,8,10 cu ft.
Ohms – Approx. 44 +/- 10%
Amps – Approx. 2.7
Watts – 325
Series AC Heating Element for side
wise/side by side
Ohms – Approx. 34.3 +/- 10%
Amps – Approx. 3.5
Watts – 420
DC Heating element (Not shown) 6 cu ft.
Continuity – yes or no
Amps – Approx 18
Watts – Approx. 215
Note: Only use DC heating element
when driving to or from a location.

To Perform a By-Pass Test of
the Cooling Unit
Disconnect the Thermister from Control Board
(with the thermister unplugged no temperature is
sensed, therefore, it will run continuously).
Place a glass of water in the refrigerator along with
a thermometer.
Plug unit into 115 VAC and allow to run “wide
open” for approximately 12 hours.
DO NOT DIRECT WIRE HEATING ELEMENT!
