Waeco CF80 Frig Freezer Operating and Fault or Problem Repair Notes

[Hodgo]

Thanks Mike

Its a weird one
the 130ah AGM battery was 1 month old at the time, and would normally only be discharged to about 12.9 static/12.6 under load after a nites running and still have enough juice for a 2nd nite/day and so on

I'm thinking of simulating the driveway thing again, but in the meantime its all working fine

cheers

I have a Waeco CF40 that I can’t control the temp on and just runs at a freezing function. I am told it cant be fixed?

Hi Beardy

CF40 fault.

your fault is symptomatic of a temperature sensor fail, or a sensor connection problem.

I don't know that CF40 at all, but the generic tests are to measure the resistance of the sensor (disconnected from the frig) to be probably 10K ohms.
I could be wrong about that value, but it is a common value.
Then check the connection of the sensor to the controller.

Sorry but that's all I can suggest.

I am not aware of its ability to be repaired.

Good luck.

I have read that some people use eBay or similar digital temperature controller when they have faults like this. Would be checking the temperature sensor first as Mike48 suggested

I bought a CF80 second hand recently. On my second trip an unusual issue came up... It worked perfectly on 240volts, but on 12 volts, it would start and operate for a few seconds then the compressor would cut out, the screen would go blank - it basically looked like no power except the fan would run for a few more seconds, then the screen would come on and it would repeat the same process. It did the same on emergency mode.

After testing voltage at the Danfoss controller, I found it would drop to 9v, after a few seconds and thus cut out. So I created new cabling. I put a 50amp connector on the unit, and used 100A cable to connect to the cars 50A connector. Now it works perfectly...

Here are some photos...

Hi all,
Can anyone provide a solution to the following problem with CF 80 Fridge / Freezer?
I recently took ythe unit out of storage and the following happens:
1. Temp set at -6,
2. Green power light is on
3. When temp reaches -6 green goes out and replace by orange after about 5 mins. (compressor off)
4. Then power is automatically turned off.
5. I've tried both the 2vov via 12v adaptor and directly to 12v battery
6. Both the same results
