Waeco CF - 80 Fridge

Sorry - I should have been a little less obtuse ;-)

The usual issue is that people have cables of too small diameter to carry sufficient current and without voltage drop.

6B&S usually is required, presuming the fridge is in the back of the cruiser.

Forgot to mention that the plug connection is very important. If possible replace it with an Anderson plug.

agree with you there Derek..I have the same fridge in my 80 series . the plug on the fridge is a twin fitting plug( cigarette lighter fitting then remove red end and fits into helle style plug) found when i first bought it had the same problem even with the waeco fitting in the back. have since only used it in the hella type fitting and had no dramas

hope this makes sense and helps to sort out the issue

cheers

I will gladly stand corrected, but I don't think the voltage cutout is adjustable on the 80 litre, but the economy/normal/high adjusts the compressor speed (varified on mine with ear against fridge), with the turbo setting higher again. The waeco has been a great unit for me, but the manual is woeful. It doesn't mention, for example, that if the red light constantly flashes, its low battery, if it flashes 3 times, pauses, then repeats, it has had an interuption to the power supply,and the comprossor won't kick in untill the pressure drops a bit. (same as an air con that is turned off and on, it comes good after a few minutes)

I think they draw 65 watts, a bit over 5 amps, so the battery should give it 10 hours at least even if it is running flat out. As others have said, checkthe wiring and battery voltages

Hi Andrew,

Just pulled the manual out to check. The switch is referred to as the 'battery protection voltage switch' in my manual. It is an old manual but came with the fridge when I bought it new back in 2002. There is a slight difference as to the markings on the switch but it shows a picture of the bottom switch/connection panel that is the same. The specs table states (alternate labling in brackets):

Cut-out V Cut-in V
Economy (low) - 10.4V 11.2V
Normal (medium) - 11.0V 12.0V
High (high) - 12.0V 12.9V

Admitedly I have not mucked around with the switch due to having a trouble free run with the fridge and no problems with flatening batteries. There is also a write up about the switch under 'Battery Operation'.

One thing I am impressed with is the fact that there is a graph in the manual that lists cable size in mm2 against distance which is great to see. For a 4m run it suggests 8mm2 and for a 6m run 10mm2.

Sounds like yours may be different to mine - is yours the digital temp set and readout model, or the older dial type? May explain the difference. Also, when my low voltage light kicks in, it doesn't stop the fridge but alternates betweenn compressor and fan???

Hi Andrew,

Mine is the older bar temp readout with the green LED's that indicate set temp. Still has the turbo button though. I think the digital temp indicator came out a year or 2 ago.

Do Engel make a 110lt car fridge?
