error light on waeco 50l.

What size wiring have you got to the socket? The Waeco needs 6mm minimum.

I use the standard socket and wiring that came with fridge?. Maybe I should check the wiring from the camper socket to the batteries?.

How many volts on the meter when the Waeco is running?

Bo,

Good advice from Brewman and Hairy. Should be able to find heaps in the archives on this problem, but a couple of points.

The 10.4v cut out is voltage at the compressor, which actually equates to about 11.4v at the batteries,

Check wiring and plugs as suggested, you can't go too heavy, and

If you haven't had it done, call Waeco and have them replace the poly fuse (warranty job). This is a recognised problem with the AC models and will cause exactly the problem you are describing.

Cheers,

Matt.

Hi big bo
If all else fails and you need to contact Waeco, the number of flashes and/or the sequence becomes important. They can sometimes read from this as to what the problem is.

Mine has been a little "iffy" too at times - been thinking that the contacts might be a bit dusty - when it does get cranky, I get a single flash every 5 secs on the error light (low voltage) - if using a meter to check supply levels in the Waeco cable or at the battery, you need to do that while the compressor is running. As you may have observed, even if it thinks the voltage is too low, it will run for a short time before it goes to error - need to assess voltage then.

Big Bo,
As stated by Matt, the polyfuse is the problem. Ring Waeco and get it changed under warranty. The standard fuse is, I think 5amp, and the fridge can sometimes exceed 5amp depending on ambient temp and so on. They will put a higher amperage fuse in there (8 or 9amp) fuse and it will work fine. When the error occurs remove the plug from the hella socket and feel the tip, it will be very warm. I had mine changed to a 9amp poly fuse and have never had the problem since. The fridge works better as well, reaching temp quicker and when I removed the plug the tip was cool.
Best way of determining if the polyfuse is faulty is to turn fridge on (12v) and press the turbo button. After about a minute or two in turbo mode the error light will flash and the compressor stops yet the cooling fan still runs. When you plug into 240v it will work fine because the 240v plug is really a 24v adaptor. When running 24v it halves the amperage being used by the fridge.

Hi,

I have seen a number of instance where this is caused by the two pin plug in to the side of the fridge. You can test it by givining it a wiggle, when it is running well, and if it is bad, it will go to error when you wiggle it. Fix is to get a new power cable. It may only show up when you have a slightly lower voltage, because the current is higher to get the same power that the fridge requires.

There is a switch on the side near the plug socket "Hi and Low" set it to low. Ours did the same on 12 V until the Waeco dealer put us straight.
