Have put a refrigerate sensor on, also in line filter and a pressure relief valve on back of compressor. The system was vacuumed and recharged. Took one and half cans of Freon and blew the pressure relief valve. Can you tell me what should be done next? Thank you !

Good afternoon,

What size cans did you use?

Can you give me the high and low pressures while it was running? I need to see both pressures.

It could be overcharged, a condenser that is clogged or stuck closed expansion valve. That is why I need to see the pressures.
