Compressor makes an awful sound

I have a 1997 Larson Cabrio 310 with a factory installed 1997 MarineAirrrrr ECU Max 12K BTU AC/Heat 110V unit.

 

When I power it up, the blower kicks in just fine… but 5 seconds later when the compressor starts, it starts to make a "grrrrrrrrrrrrrrrrrrr" sound and within a few seconds trips the breaker on my panel.  Compressor appears to be shot.  If I have to, I will replace the whole unit… but the rest is in fine working condition, it would seem a shame to scrap the whole thing for just a compressor.

 

The compressor number is RK136AT-002-A6 (RKA5510EXA) and is filed with 20oz of R22.  Where can I get a replacement compressor for this unit as inexpensively as possible?   I spoke with a local marine air guy and he said the compressor is about $600 and another $400 to braze it onto the unit.

 

Can this be done cheaper?  If I'm going to drop 1K, I would rather do it on a new unit.

 

Thanks,

Hi Rick~

I suppose it could be done cheaper if you could find a compressor for less…Problem with getting one from a standard A/C supply house is if it will match up in the system & run the proper pressures…Often times HVAC supply's provide the "closest" match…Which may not be all that close…But it's cheaper…Then ultimately the unit does not perform well, or the replacement fails shortly due to the mismatch…and you still have 1997 unit with little if any warranty… 

Your service guy seems to be quoting Marine Air pricing for the correct compressor, and I don't blame him…I''ve been there before too…

One thing about your control…The ECU MAXX was their top of the line control at that time…It was expensive then and more so now that they only offer replacement boards, but no replacement displays…

That board retails now for over $1000.00

If you do decide on a new unit & control…You could sell that ECU Maxx setup on E-bay or the the like to recoup some or your costs…

I do sell new units at discounted pricing, and a new Turbo unit will out perform your unit in every way I can think of…

If you are handy you can install it yourself…and I'll be here to help you along…

Steve,

Thanks for the followup and the tip on selling the parts of the ECU Maxx on Ebay.

 

Regarding the unit you sell…. does it have heat as well?  Can you send me pricing?

 

Thanks,

I too have a compressor doing the same thing.

My unit is a marine air VCM12K. I was able to get the model # right of the compressor and found the same compressor at an online supply house in Indiana for $130 shipped.

Now I plan to remove the unit from the boat and bring it and the new compressor to an a/c guy to have him put it together.

I was doing some calling around on this and was quoted $550 for putting the compressor in the unit, this seems steep to me.

 

Can you give me an indication if this is within the ballpark and is it necessary to flush the system, I am worried that the bad compressor would have contaminated the system. Those that I got quotes from did not plan on flushing as they said it was not needed.

Below is the actual training PDF that Cruisair uses in their Service Schools…

It may be more info than you want to know but it does cover recommended procedures for compressor replacement.

As far as what local shops might charge to do what they do…I can't comment much on that  Confused

Thank you Steve,

 

I had found that online too and because of these instructions I was surprised that none of the shops I contacted was recommending flushing. My question than to you would be would you? or are there some simple things that can be checked to see if it needs it.

To answer that question of would I ???….I'd have to do the "Simple" smell/acid tests described in that PDF to determine if flushing was warranted/needed…

How old is this unit ?…I don't show that model # in any reference material I have….If it's old enough to have a piston type compressor I might reconsider repair all together…

Maybe I'm not on the "Right Side" but for me it has always been the "Preferred Side"  Cool
