Aircon condenser

Hello , another daft question
Had the disco in for an aircon recharge and it failed the vacuum test so there is a leak somewhere
I've checked all the pipe work and everything looks to be in great condition with no corrosion so this leads to the condenser.
Pulled off the grill for an inspection and it looks in pretty good condition no obvious rot , but when I was touching the fins the top half seem quite solid but the bottom left ( the bit that's prone to rot ) when I touched the fins the seemed to start collapsing under finger pressure can I assume that that's the probable cause of the leak or is that quite normal
I've a groupon voucher for the aircon refill so it seems daft to me to pay for another regas to find out the cause maybe the condenser and then go and buy a new one
Any ideas anyone
The condenser seems to be the weak point Thumbs Up

Leak

Needs leak testing using a mix of Hydrogen/Nitrogen and a sniffer to detect exactly where the leak is coming from, 99% of the time a stone hitting the Condenser causes this, but without the right equipment you won't find it, you could potentially fit a new one and still have a leak, my advice is get it leak tested.

Normally a die is used when filling with gas which shows up under ultra violet light to determine the point of the leak.

This means of course you have to do the gas refill, but it can then be easily recovered from the system by the service operator, there and then, once they have identified the leak. Generally speaking its usually the condenser but not always. Sometimes its possible to identify the area as it can be wet with the oil which has escaped with the gas. Pipes with a pinhole, and the pressure switch are other common areas for leakage.

The heat exchanger metal bits can come out without leaking gas.

The core bits of metal need to be ok though.

Wipe any suspect bits over with white tissue and see if you pick up any yellow dye

This is illegal. Anyone caught doing this risks losing their licence

The correct method of leak detection is OFN/Hydrogen, as above Thumbs Up

😩 like I did.

Aparently my condensor was the cause of the aircon not working so got a new one (from AF of course) and £500 later in parts and labour the air con lasted around a day or so. Looks like I have an additional leak so its back to filling the penny jar for the next installment but in the meanwhile I shall have to melt Confused

Well that's me told Bow down I wasn't aware of this perhaps because my machine (R134a) is 10 years old now.
Thanks for the correction Mikey Thumbs Up

Do you know if that's a UK or EU directive Mikey? I haven't heard about it til today. I imagine it applies here too but hope I don't have to change the machine Sad

One would expect it to be a Europe wide thing. Few different conventions restricting use of R12 and phasing out of 134a...

For a while now it's illegal to gas it up knowing it's going the leak.

But many do when it's a slow leak. They put a little in.

America is using a new gas. It's flammable. 🙄
