2012 Airton air conditioning: list of error codes, crazy F5 failure!

[Christophe]

When I wanted to restart my Airton reversible air conditioning (bought from Brico Dépôt in 2012) after a few months of shutdowns, I got an F5 error code.

F5 corresponds to a compressor thermal shutdown (Klixon) difficult to understand after X months of shutdown so I had doubts about this self-diagnosis.

And when I tested on the thermal quick connector I had continuity!

I spent 2 days diagnosing the fault, tested all the other sensors, in particular calibrated the NTC probes (telling myself that the error codes are not 100% reliable?) to finally find it was a false contact in the connector quick of the klixon !

The thermal was good, the wires too but there was a bad contact with the connectors (1 or 2?) when it was plugged into the power board !

The continuity test is done on the side of the quick connectors, not on the pins.

So I removed this quick connector from m... and I made a direct connection to the power board... and mazel tov, it works again (for 10 years I hope!)...

In short, I spent 2 days to repair this breakdown instead of 15 minutes... the crazy breakdown! If it can benefit others...

I am convinced that a pro would have said, after 2 or 3 hours of hair-tearing diagnosis: power board dead, air conditioning to be changed!

In short, the error codes on the old air conditioning are a jungle, so here are the error codes that correspond to this old air conditioning (do not count on the Airton after-sales service, which is absolutely useless...)

It's often like that. You measure with a very small current generated by the ohmmeter but not with the real current in operation.
At the same time, we forget to measure upstream, while moving the intermediate connections.

I am convinced that a pro would have said, after 2 or 3 hours of hair-tearing diagnosis: power board dead, air conditioning to be changed!

Or change the card, which would have been more profitable for him. Diagnosis doesn't always help, but still involved the correct circuit.

I had a breakdown of this style on my last car bought new. It took almost 3 years to find the intermittent failure that caused it to go into limp mode, sometimes on the highway. You went from 130 to 80 all at once. With parts changed for nothing, obviously out of warranty. Finally it was a relay that was burning.

The continuity of a klixon is done at low voltage… I don't think it's 230 that goes through it.

The measurement without the quick connector gave the same thing. It was indeed a mechanical problem…a few tenths of a mm…

Sometimes you have to measure before the connectors, with a very pointed test tip that you push into the insulation to come into contact with the copper, without pushing it into your finger.

In another life, when I installed radiotelephones on vehicles, I used a small cutter to which I had welded a wire to the metal blade guide. Also practical when installing a trailer harness.

Yes, just a needle is cleaner
It can also detect when a copper wire is cut in its sheath.

In the same genre, suddenly a breakdown on a tractor...
I made it short but it was the pins of a fuse that had oxidized

Well I hope the reliability has improved at Airton, I just ordered one 15 days ago (this brand is no longer sold at Brico, they have probably found an even craptier brand)

Always a joke…Forhorse!



Well at least you will save time with the error codes!! Hehehe…
