My A/C Keeps Exploding

[puppykhan]

While driving my 2024 Willis 4xe, I hear what sounds like a small explosion, see a puff of white smoke come out of the engine area, then the A/C no longer works.

I had this repaired. A hose burst, and lost all the Freon. Freon is expensive to replace, like a thousand or two.

Then it happened again a few months later.

The repair is supposed to have its own warranty but still.

Anybody else having trouble with their A/C like this?

I am pretty sure there hasnt been others, at least not posted on here.

They dont use Freon anymore but yes, the refrigerant is spendy.

Freon is now used to spray on baby seals and punch them through the atmosphere in the Artic, or it was banned in the 90s due to ozone layer decline. I cant remember which.

Never heard of that issue. Just let the warranty do its thing. For the future, when you run low on Freon(refrigerant), I still call it freon, the 1234xyz? can be replaced with the older, cheaper, and just as good 134a Freon. You just need a $15 adaptor to charge it.

I hope they look for an obstruction in the expansion valve. Something is driving the high side pressure up and that can destroy the compressor.

expansion valve is a common fault on these but i've seen failed compressors a lot too. it's one or the other i'd say

I'd also suggest to have them check the high side pressure sensor.

From what I can tell from my poking about while trying to resolve my own pitiful cooling performance, the system regulates the compressor based on the high side pressures. I could see a scenario where that pressure reading is very off and the compressor is commanded to run way faster than it should, and cause hose after hose to burst. ... But that's just a quick arm chair guess.

If you have the JScan app, go to modules, Hybrid Control Processor, Live Data, and search for AC data... High side pressure is in there.

the compressor should blow out of its relief valve before a hose blows
