Fridge cutting out

[foggs]

Hi

I've got a Waeco cf40 fridge and I went to put in the the back of the patrol today to cool it down to chuck the lunch in for a picnic. When I plugged it in and turned it on the display said it was at 20 degrees but after about a minute or not even the fridge cut out then after a minute of it being off it turned back on and did the same thing again. So I connected the fridge to the house power to cool it down first then once it was at about 2 degrees I connected it to the car and it worked good for the the hours drive and while we were away.

My question is, does this mean that the wiring from the battery to my rear cig socket for the fridge is not big enough and is loosing too much power on the way.

The socket was already in the car when I purchased it too.

I'm not the best with auto electrical stuff so Thanks in advance.

My CF80 did the same thing one morning when i checked it, the error light was flickering until I ran the car. Here's the explanation from Waeco:

What are the battery protection levels?

There are three set-able battery protection levels;
"Hi" equates to 11.8 volts (High cut-out)
"Ned" equates to 11.2 volts (Medium cut-out)
"Lo" equates to 10.1 volts (Low cut-out)

These are the voltages sensed at the refrigerator under load at which the compressor will shut down to protect your vehicle battery.
If you have a small battery in a smaller vehicle, you should select high so that you are able to restart your vehicle easily.
If you have a larger vehicle and larger battery capacity you should select the medium setting.
If you have a dual battery set up and the secondary battery is able to be isolated from the starter battery you should select the Low setting.

What do the "error" flashes mean?

If the power LED is flashing once every five seconds this means that the refrigerator is sensing low voltage. The battery needs to be recharged or the wiring in the vehicle may be inadequate, or, you need to adjust the battery protection level to a lower setting.
The error LED flashing means;
Twice every 5 seconds: The fan has a problem. Is something jamming the fan blade such as a pencil poked through the vent by a child? If not, the fan may be faulty and you should contact an authorised service centre.
Thrice every five seconds: Power may have been interrupted at a critical stage of the refrigeration cycle. Switch off for ten minutes then restart the refrigerator. If problem persists, contact an authorised service centre.
Four times every five seconds: Compressor struggling to achieve speed. Switch off, wait 10 minutes then attempt restart. If problem persists contact an authorised service centre.
Five times every five seconds: The unit is overheating. Check that the vents are not blocked by other equipment in the vehicle. It is easy for example to toss a sleeping bag in the back of your wagon and it could roll against the vent causing an overheat situation. The vents should be kept clear at all times.

What is the emergency Switch for?

The emergency switch should be left in the "Normal use" position at all times, except if you cannot get the refrigerator to switch on for some reason. Switching to "Emergency override" feeds power straight to the compressor so that you do not lose your foodstuff. The thermostat control is overridden when emergency override is selected and the compressor will run constantly which may cause fresh food to become frozen.
Manual turning on and off will be necessary to prevent that until service is arranged.
