Compressor running and 50psi gass. But no cold???

Post by Axa » 30 May 2018, 16:26

Espace 2008. Regassed with Envitosafe gass to 50psi as i also did last summer and AC was cooling good. Compressor engages fine and makes pressure to drop to about 30psi.
The GPS screen did go dark in the beginning of the winter so I'm not sure if the outside temperature sensor is working as the temperature is supposed to be displayed on that screen.
I have opened up and cleaned the cabin temperature sensor with electro clean spray as the fan was annoyingly noisy. (Still is)

Any suggestions? We really need the actual to work now as our dog don't do well in the heat..

My advice is that once the system is not working, there is no alternative but to have the system evacuated and a known weight of gas added before measuring the pressures (low and high side).

This sounds like it needs to be checked by someone with professional kit.

Just because the compressor clutch is pulled in doesn't necessarily mean that it's actually pumping. If you're having to add gas every year something needs sorting anyway, really shouldn't be needed any more than every five years or so.

Could be a duff compressor, could be a blocked expansion valve/capillary tube, could be the control system having a fit, could be a solenoid valve not opening...but without having the pressures on both sides of the system checked and an appropriate charge weighed in you're trying to work blind.

Any decent outfit should do a leak down test while it's under vacuum too which should show if there are any leaks that are a serious issue.

...with the price of refrigerant these days, *any* leak is an issue!

I've just done a search on all the usual suspects for re-gassing, the price is £60 ish everywhere for the full treatment.
My local garage will do it for £50 for me as a trader...……….he said "If I was you Eric I'd just wind the windows down." :-D

€40-45 here. Most garages have the pukka kit. A 50-minute job, with proper evacuation and recharging with gas+oil, and pressure checks.

Bit of a trek from Norway, though... 8-[
