Marine air Question

Had the reverse cycle heat on last night. 3 units running. This morning one unit had tripped its breaker and shutdown. Turned it back on and it tripped the breaker again. I let it sit for an hour and tried again. This time it displayed an error code that is defined as "high current." It attempted to restart and then ran just fine.

Does anyone know the meaning of "high current?" Should I be concerned or keep running it?

Thanks all.

Did it actually report "High current" or a code that you believe reflects high current?

Similar to Hi PS?

No, high pressure is different. The actual code was H-C. Checked the manual and it is defined as high current.

BTW, the incoming voltage measures 120V

Greetings,
Mr. hm. Are you anchored in a river with a large tidal flow?

If the unit was running and the pressure was building as water flow decreased, amps (current) will increase as the compressor works harder and gets hotter . I would check for a restricted water flow as well as a loose connection or wire. Clear fault, and check water flow after cleaning. If the boat was dry docked ,and now in the water ,might have air lock at that units water supply.

Boat is at our YC slip. Water flow is fine, strainers are clean. All units run off the same raw water pump and the others run fine as well.

Have you contacted Marine Air/Dometic?

No. It's running fine now. I guess I should though.

Maybe the reversing valve is hung up. I have had that happen and the breaker trips. To free it up I jumpered power to the solenoid and cycled it a bunch with the unit off. I have had this happen twice in the last four years. The method freed it up each time. My units are 1988 models.

A reversing value will hang up if not cycled . Some unit cycle the valve for cooling ,others only on heat. Good idea to cycle the system every couple of months or so.. With three units on one pump ,I would take a amp reading of each unit, and see if that one is working harder . Water will flow to the least resistance so maybe that unit has less water because of the distance of the run. I installed a pump for our two forward units and one pump for the aft cabin. Had a water flow problem with one pump for all three units. No problems since. Just because water is going overboard don't mean the units are getting the water flow they need . If you have a temp gun you might see a higher discharge temp.

Thanks all. The reversing valve must have been the issue as I have now run the unit in both cooling and heat mode with no further issues. I will exercise the valve every now and again in the future.

I'm also now considering adding another raw water pump for the furthermost unit as it does have significantly less water flow. (This was not the troublesome unit.)

"Marine air" ....
Sounds like a weather question to me.

A stuck reversing valve can usually be freed up by tapping on it with a tool handle or hammer. "Tapping" is the key word here, not pounding.

I haven't had the opportunity to look at the unit yet as it is working again. However, for the uninitiated, could you describe what the reversing valve looks like? Thanks

Agree, but that didn't work for me so I went the next step.

See the valve in the center of the coils?
