Trouble-Shooting
E. Checking the Fan
1.
The fan should come on after a five second delay once the
compressor starts.
2.
Visually inspect fan for any blockages and make sure that it
can turn freely.
3.
If the fan can spin freely and is not working then first check
the fan terminals “+” (the smaller of the two ”+” symbols) and
“F” on the module for voltage (Figure 7.0).
4.
If there is voltage at the module terminals then remove the fan
wires from the module and check for continuity through the
fan itself by placing meter leads in each fan wire push-on
terminal. If there is no continuity through the fan then replace
it.
F. The Refrigerant Circuit
1.
If the refrigerator seems to be running properly and passes all
of the above tests and there is no cooling in the unit then the
problem may be a refrigerant leak.
2.
Do not attempt to charge unit in field. Contact your
service dealer or Dometic Corporation at 804-
746-1313 or 954-973-2477. Ask for the Tundra
service department.
