Troubleshooting
NOTE: The 242 gallon freezing unit does not have an alarm
LED.
CAUTION: Before performing any service,
disconnect the battery cables at the battery and also
disconnect the AC supply.
The ColdCube has a built-in self diagnostic program. If there is a detectable error, the red LED light positioned nearby
the digital controller will flash 1 to 5 times and repeat the pattern, showing the possible reason for the operation
stopping.
(Note: the 242 gallon freezing unit does not have the diagnostic LED.)
1 Flash Battery protection
cut/out The battery voltage has fallen below the cut/out setting. Check the source
battery for proper operation and sufficient voltage output. If power source is
adequate then check wire sizes and conditions of the connectors to avoid
voltage drops. Charge source battery.
2 Flashes An over- current
cut/out The fan loads the electronic unit with more than 0,5 A (avg) or 1,0 A (peak). Fan
may be blocked, fan wires may be loose or damaged or the fan motor has failed
and is drawing over/current to protect itself. Visually inspect fan for blockage,
check wires for chafes or loose connections and repair. Or if fan has failed then
replace it.
