I have an old Mermaid reverse Cycle system...12K BTU and likely as old as my boat. It was working just fine but recently developed an issue. Just looking for some feedback before I start pulling things apart.
The compressor starts up upon signal from the thermostat. The evaporator coil goes Hot or Cold depending on my selection so I've pretty much ruled out the compressor. Water Pump and circulation are fine.
The problem is the fan does not come on in either manual or Automatic mode.
I can hear the fan relay click when kicked on from the thermostat, but no fan rotation. Occasionally the re-set circuit breaker on the unit will trip.
At this point I'm suspecting a bad or seized Fan motor, though it could be relay contacts.
Anyone have any experience with a similar problem? I'll start my troubleshooting this week...
