Marine Airrrr A/C

[mjvalliere]

Good afternoon, I have a marine air a/C heating system the system powers up but is not sending 110 V to the water pump">raw water pump. I have power on both sides of the 6 amp fuse but nothing at the pump. Any ideas

Appreciate any advice of what to look for

The pump doesn't have its own breaker, does it? I had a boat that the breaker for the A/C included the pump. My current boat has a breaker for each A/C unit and a separate breaker for the pump.

What 6 amp fuse?
I believe they all power the pump through the “control box” sorry I don’t have a better name for it, but that may be the problem.
I assume this 6 amp fuse may be located there?
But there most likely a relay, it could be a relay or whatever controls the relay.
Have you tried calling the manufacturer? They may have some trouble shooting steps you may can follow.
Sorry I couldn’t be more help, maybe someone else can

If you’ve got power at the fuse (I’m assuming this fuse is for the pump), have you checked for power @ the pump?

These pumps typically come with a 3’-6’ cable lead, any further away from the ac unit than that requires a junction of some sort.

If there’s power @ the junction, you may have a dead pump, or a stuck impelller.

Does the pump make any noise at all? Does it jerk or vibrate when it should be energized?

Same here. One other thought, is the OP making the assumption the pump isn’t working because no water is coming out? Possible plugged strainer, or air locked water plumbing are also possibilities.
