Hi CampAround,
I purchased a ARB 47L fridge for my Cub Escape back in October 2009, It has preformed perfectly for 2 years and 9 months, then one Sunday when I switched it on the temp reading showed 43 deg C !!! when it was low twenties here in Brisbane, I left it running for approx 1 hour and the temp as 28 deg C, and the thermometer I placed inside the fridge showed -7 deg C, I checked again about a half hour later and 35 deg C was shown in the display and inside it was -15 deg C, It did not look good.
Tuesday morning I took it down to UV4X4 at Enoggera (Brisbane) as it was still under warranty.
on Saturday I picked up a brand new in the box 47L ARB fridge as a replacement.
It turns out the thermistor (which is the temperature sensor) had gone bad.
In the first batch of the 47L fridges ARB made it was not possible to replace the thermistor.
This problem was rectified in the later batches and the thermistor is now a replaceable part.
The first batch of ARB 47L fridges had a duller yellow LED temperature display, later batches have a bright white LED temperature display.
If you are looking at buying a second hand ARB 47L fridge I would check the serial no with ARB to make sure it has the replaceable thermistor. If it has the bright white display I think it would OK.
I must say I was VERY pleased with the service from UV4X4 and ARB to get this issue resolved easily and quickly.
I am considering the smaller ARB fridge for the TUG (when I find the pennies).
