The cooling unit is out - what now???

Dave,

Here's the web page for the 3-in-1.  It's in Adobe.  Page down to where it says " RCO Series 3 N' 1".

Dave,

I have a Word document for you with photos and info.  Shoot me an email to waynestrine@yahoo.com and I will send it.  It's too big to post here.

If the cooling system is working now I wouldn't replace the relay. if it an't broke don't fix it I allways say.

Josh,

I agree, except I don't know if Dave would be able to rewire without buying a 3 N' 1.  My Vendo 56 (60's) has the relays external to the compressor, but my Cavalier 51 does not.  So, to rewire it, I had to get a 3 N' 1.  I think Dave may be in the same boat with that compressor from the 39.  It looks like one of the earlier models, as it doesn't have a condenser fan and relies on convection.

Hello Wayne and others.

My wiring harness arrived the other day and I have just got around to trying to work out how to wire it all up.

Wayne I think you were right when you said it was not going to be as simple as just plugging in all the wires.

The harness is from Funtronics and appears to be the universal one sold for most models. The difficulty I have, as highlighted by Wayne is attaching the power cord to the compressor. The wiring diagram shows the cord attached in two places, one to the start relay and one to the overload relay. The only cord I have coming from the compressor is attached to a three pin plug which then goes into the orignal wiring harness and splits three ways. I guess this is the three in one.

I have enclosed pictures below. Do I need the added piece of hardware in order to re-wire??

Thanking you in anticipation.

Dave

Dave is the compressor manufacture listed on the baseplate?

It may be a Techumseh, or a Blissfield, possibly a Copeland,
this will help us identify the pinout. the three pins that the female connector attach to are the "run", "start" & "common" terminals.

The "three-in-one" (3-in-1) referred to in prior postings is a modern universal replacement for the rectangular start-run relay shown in your picture, the attached diagram will give you a basic picture of what it looks like.

Dave,

JohnieG is the best with his photos.  You'll need a 3 N' 1.  Funtronics sells them, but they are about $25-30.  I can try to see if a local HVAC store has any.  I bought one from them one time and paid about $15.  Then, the only other cost would be shipping to you.  

Question for all:  If this is what Dave needs, does anyone have an extra one laying around to send Dave?  If not, Dave, I would be happy to see if I can get another one for you and mail it to you.  I'd only ask for the cost of the item and shipping.  It's about the size of a small aerosol can.  I think the Word document I sent you had a photo of one in it.  I think I also put in the page with all the diagrams of the various compressor pin-outs, too.

If you send something to Dave be sure and mark the customs form as a "Gift" and a low declared value.

Hello Everyone.

Sorry for the delay in replying. My electrics were out last night. Major grid problem. Didn't come back until the early hours.

Johnie - The model is a Kelvalator (think that's right) model no. V12S. Hope that helps.

Wayne - Thanks for the offer hgopefully you got my PM

Creighton - you are so right about marking it up as gift. The box of bits I got from Funtronics cost me almost $70.00 in import duty. The government add the cost of postage to the goods before taking their cut. That really is sneaky.

Dave,

I'm going to stop by the store today (Friday) and see about that relay.  I'll let you know something tonight after I get home from work.
