9 Troubleshooting

Symptom
Unit is running all the time
*-If the section of the evaporator plate
holding the thermostat tube isn't lightly
frosted the thermostat tube will be sensing
incorrectly.
Fridge not running
Fridge not getting cool enough
Evaporator icing up
Version 2.6
Reason/Solution
-
Evaporator has excessive ice, defrost unit to remove ice.
-Condenser is not removing enough heat. Check condenser
cooling is sufficient.
-Fan is not working. Replace fan.
-Faulty thermostat. Replace thermostat
*-
Have a refrigeration technician investigate the
possibility of a refrigerant leak.
-Fan is sticky or stiff. Replace fan
-Voltage too low. If battery voltage at the compressor
module is less than 9.6 volts at startup, it will not start.
-Check your DC power system.
-Check that a connection or cable has not come loose
-Thermostat is set to low. Turn the thermostat to a higher
number. (if at 3 try at 3.5)
-Ambient temperature is high. Open the fridge door less,
and try to improve colling over the condenser.
-Door not sealing properly. Fix door or replace door seal.
-Door is being opened too often. Always limit the number
of times you open the fridge door.
-Door not sealing. Too many heavy products in the door
during travel, or the door is being leaned on when open.
Re-adjust the door to seal.
-Door seal split or damaged. Replace door seal.
(During humid times, the icing up will occur more quickly.
Ie. If you are in Northern Australia during the wet season,
expect to defrost weekly)
