Although it looks like P5...It's really PS...And there are two different PS faults HI & LO....

The display should alternate from either HI then PS, or LO then PS...

LO/PS is low pressure...Usually meaning loss of air flow, or loss of Freon.

HI/PS is high pressure...Usually meaning you have reduced or no water flow.

Though you didn't say what brand of equipment or control you have...I'm assuming you have Cruisair with SMX digital control...

AC runs couple minutes at best and AC shuts down and displays code P5. Previous owner only used AC once about 3 years ago. Checked all valves/filters etc., still no luck. Does anyone know what this error code means and where I might find a list of all codes for future reference? Tks. mandjsig27
