Chapter 6 - Troubleshooting
Cooling will not come on or will not hold constant.
First: Make sure the temperature set dial is set to a lower-than-
ambient temperature.
Second: Press the cooling on/off switch several times and make
sure the amber light in the switch comes on. If the temperature set
dial is set to a lower-than-ambient temperature, the system light
should also come on. If the system light does not come on, it is a
strong hint that a deeper problem exists in the cooling system.
Third: Check the circuit breakers to be sure they haven’t tripped.
Reset them if necessary. Refer to Re-setting the Circuit Breakers
on Page 60.
CAUTION: Before working on the electrical system,
make sure the unit is Off and the electric power cord
un-plugged.
Fourth: Check all wire connections behind the cooling on/off
switch, on the thermostat, and on the cooling system.
Fifth: If none of the above fix the problem, you probably have a
defective thermostat or cooling system. Try operating the heat
system. If it too fails, replace the thermostat. Order P/N 853421
and refer to Page 113 for replacement instructions.
Sixth: If the thermostat is OK, a problem exists in the cooling
system. Call SSCI Customer Service at (800) 323-7366, or a
certified refrigeration serviceman.
WARNING: Do not attempt to work on or dis-
assemble the cooling unit as it contains MP39
refrigerant gas under pressure. If service is required
on the unit, call SSCI Customer Service at 1-800-323-
7366, or a certified refrigeration serviceman.
