A/C question for a 1987 45 Hatteras SF

[Gina Marie]

Is it normal I have two central A/C with one water pump. I normally never run just one a/c but the other day I turned on just the staterooms which have two blowers forward and mid in the master. The water pump did not go on. When i turn on the salon the water pump is on. Normal??

Thanks

Yes that is a normal setup. Sounds like you have a bad pump trigger for the stateroom compressor. I'm guessing the stateroom units periodically trip the high pressure switch.

Make certain that the the stateroom thermostat is set at a temp that will call for heat or air otherwise the water pump won't be on.
