6. When connected to a vehicle wiring circuit with the vehicle
running, the fridge occasionally shudders or stops operating.
6.1 It is likely that there is loss of voltage occurring within your vehicle
wiring.
 This can be confirmed by taking a voltage reading at the end of the power
lead for the fridge while the fridge is running. If the reading is below 11.8 volts
(12VDC) or 24.1 volts (24VDC), you should have the wiring system checked.

If necessary, upgrade your fridge wiring circuit using the information in
section 6.4.4 as a guide.
7. The fridge stops and starts or runs erratically
7.1 The internal battery protection system may be causing the fridge to
switch off because the battery voltage is low.
 Check whether the voltage supply at the fridge plug has dropped below the
shut down voltage listed in section 6.12. The voltage must be read at the
fridge plug as there is normally at least one to two volts lost between the
power source (battery) and the fridge plug.
 The vehicle battery may need replacement or the wiring to the fridge may
need to be upgraded. Refer to section 6.4.4 for details on wiring requirements.
8. The fridge is running too long and is not cooling properly.
8.1 Good fridge performance, especially in hot ambient temperatures, is
dependent on good air flow around the fridge cooling slots.

Check that all ventilation slots are unobstructed and there is enough
clearance for good airflow around the fridge. Refer to section 5.1 for details.
9. When the fridge lid is open, the LED cabinet light does not come
on.
9.1 The fridge may not be connected to a suitable power supply.
 Check the connection between the power source and the fridge.
9.2 The fridge may not be turned on at the control panel.
 Turn fridge on at control panel.
