View Full Version : Looking for a challenge? Help me identify and replace this compressor!

Carrier used to manufacture a great RV rooftop air conditioner unit. I have several of these, and have been working on rehabilitating them. Normally they are the most efficient units compared to other brands, drawing about 13 amps while running. One of the compressors seems to have died, but I haven't been able to successfully identify the specs to try and replace it.

The model is a Carrier Air V, model number 68RV14113A
From the placard on the unit itself:
Part number 99-00468-33
115 volts, single phase, 60 hz.
System design pressure 350
R-22 refrigerant, 23.3 ounce capacity
Compressor RLA 10.8
Fan motor FLA 2.43
Nominal BTU capacity 13,500

Everything on the compressor itself:
51 L2707 D2 063826
80441913901 BC
stamped in casing:
027178 or B
U2957 8 or B

Any help anyone can offer, I would much appreciate it.
I would also love to replace the compressor with something that can soft-start if that is possible, as it would greatly reduce the load on the generator or other power source. I had the idea of using something like an inverter scroll compressor without a variable controller - so the compressor would (hopefully) soft start and run at it's full power on the same on-off cycle that the existing compressor runs with. Is this even possible?

I will give a call to that Carrier distributor and check, but the last one that I spoke with said that there weren't any parts available from the Carrier distribution stream b/c they are no longer being made.

Thanks for the service manual too - I already have that though - and the only part numbers it has seem to be internal numbers from Carrier. Obviously this compressor would have been sourced from somewhere else, that is what I am trying to figure out, or just match the performance characteristics. I am guessing that it was a Samsung unit, but haven't gotten much further in my searching yet.

One observation I made of a different unit (I have like 5 of these) is that the 15,000 btu model is rated for 15 amps total draw... And when running, the compressor on that one had been pulling over 28 amps. Evacuating the system and changing the dryer before re-oiling and recharging got it down to 22 amps and great cooling... But it is still obviously too high of a draw. I suspect this compressor may also be on its way out. :(
