Hello,

1997 Island PacketCat 35, South Florida, Miami. Installed "after market" ???

A/C unit in question: Marine Air System, 1997 vintage, VCP7-16K self Contained Passport II controller

The unit will come on from the control panel, but the air from the vent is not cold.

The unit had been on the HU Setting. We lowered the temp and the Cool indicator lit up, the fan started but the discharge air was not chilled, and no water is be pumped.

The  water lines and raw water filter are clear, the through hull is open, there was no fault code on the read out, just no cold air or compressor operation. I " reset" by turning off the power, reset factory defaults on the program, tried the heat cycle, but no luck.

I got close to the unit and had someone turn it on; the unit clicks, actually 2 clicks, the blower fan starts, but the compressor won't run or the pump start to circulate water.

Am I doomed? What could cause this?

Hello,

There is no amp meter in this circuit. There is a breaker but the Air Condition is on it's own breaker.

I didn't notice the lights dim, but cabin lights are 12 volt.

There was a fan running during our trials of restarting and resetting, and I didn't notice any draw down in speed.

Hello Steve,

I'll check per your instruction.

Just to be clear, there is both meters in the main panel, however the AC unit is on it;'s own beaker and not connect thru the main panel.

I'll have to move the unit to get to the terminal board, installer has that side of the unit up against a bulkhead so cover cannot be taken off with out moving, ah well!

That's correct, the compressor isn't even trying to start, the only sound is two clicks and then nothing.

Thanks again for the prompt reply.

PS What if the board is gone?

Hey Steve,

I opened the box and checked the various terminals; L1-L2, 110v, Fan L1-L2/valve 110v, Comp L1-L2 0v, Pump L1-L2, 0v. This with the snow flake showing on the control panel, and the fan running.

So do you think it's the board? or Comp relay on the board? Can it be repaired, or do I need to upgrade to the new system Passport I/O?
