General Ducato pressure switch

[Mully59]

Does anybody know if the air con pressure switch can be replaced without all the pressure escaping when it’s unscrewed. 2013,2.3. Thanks Mully59

Unlikely
Wants the system 'vac'd out 1st

And if you are opening the system..
You really want it pressure : vac tested before refilling

What pressure do you currently have ?

Hi, I had it pressure tested all ok, old refrigerant removed and new oil/leak test colour put in and new refrigerant put in but still not working, they removed new refrigerant and didn’t charge me, said possible faulty pressure switch. I just want to remove old switch and fit new one before they refill system,just wanted to make sure it won’t blow off when I unscrew it.Thanks for the reply.
