Thread: Got a Waeco problem

I had a similar problem...but first
Does it perform the same regardless of whether it is on 12v or 240v?

My problem was on 12v only and it ended up being voltage drop in the wiring loom due to a poor connection.

I have the same model refrigerator. It is 12V/24V only. There is no onboard 240V option. The problem seems to be low supply voltage. This could be due to a flat battery, or a voltage drop somewhere in the line. Suspect the line plug. They have a poor contact area on the central contact. This then generates heat and melts the fuse holder in the plug. Replace the plug with a dedicated merit plug, or better still, hard wire it. Also check that the three position low voltage cutout switch has not been set to high.

I have only tried it on 12v powered batteries. Both were charged. Dont think my.model runs of 240 directly. Ill jave to check

Did you have it directly connected to the battery or in your car? Do you have access to a multimeter?

From another forum, but useful info

One Flash

Can be caused by:

• Insufficient cable size
• Too many connections
• Poor connections
• Not designating fridge
with own direct circuit
from battery

Battery Protection Cut-Out

If the error light on your fridge flashes once every 5 seconds, it is definitely indicating that you have a voltage drop problem. This means that the wiring in your car may be inadequate to carry the correct amount of volts to the fridge. To test if this is the problem, plug the fridge into a suitable AC adaptor. If you find that the fridge works, you can eliminate that there is a problem with the fridge and the car wiring configuration or plug connections should be stringently checked.

We recommend car/motorhome/caravan wiring to be a minimum of 6-8mm cross section wire for up to 4 metres. Above this length the wiring would need an extra millimeter for every metre.

If the fridge does not work on the correct WAECO AC Adaptor, further investigation is required. Contact WAECO if this occurs.

Two Flashes
Fan over current cut-out

If the fan circuit in the control module has a load in excess of 0.5 Amps, the system will fail.

Three Flashes
Motor Start Error

If your error light is flashing three times every 5 seconds, the rotor may be blocked or the differential pressure in the refrigeration system is too high. Faulty compressor or faulty control module.

Four Flashes
Minimum Motor Speed Error

This failure occurs if the compressor is running slower than 1850 rpm.

Five Flashes
Thermal cut-out of electronic unit

If the error light is flashing five times every 5 seconds, the refrigeration system has been too heavily loaded, or if the surrounding temperature is high, the electronics will run too hot. This is generally caused by not allowing enough ventilation around the vents of your fridge. To overcome this, simply ventilate your fridge more effectively.

Ive had to replace the power lead twice on my waeco, it is a early mechanical thermostat unit, basically the internal of the plug hot jointed in the fridge end, once I replaced the lead the fridge worked perfectly.
Ive had to replace the plug tops a couple of times since but always check the fridge end first.

Cool stuff. Thanks for all the great feedback. I'll check for voltage drop in a more stable invironment. I take I need to open the box and get to the wires on the inside.... is that correct?

On a nother note. Does any one know how to tap into the existing thermostat?

Hi guys.
I pulled the side of to get to the wiring. So the multimeter drops down below 10v when the compressor kicks in. This is off a 12v battery outback battery pack fully charged. Is the drop to just under 10v jormal?
