Help at identifying a relay...

[Cheekychimpo]

Hi guys, this is my first post so "howdy"
The problem Ive got is to do with a air compressor, but the parts that are broken relate to fridges I think.

The part is branded Klixon,cant see any other I.D. numbers.
Tried to post pics of the item but I haven't submitted enough posts on the forum.

Can anyone host me a few pics?

The question is where can I get replacement relays for this vintage equipment?
Please try and keep it simple Im not a trained engineer

Thanks in advance Paul.

Hi Paul and welcome to the forum.

When you say 'Air Compressor'....is it like a domestic refrigeration compressor.....i.e. a circular/oval pot like at the back of your fridge?

Does the compressor have 3 pins on the side, and the relay pushes onto the lower two pins, and has a coil of thick wire (golden coloured) on the lower part?

Are there any makers ident marks on the compressor?

[Cheekychimpo]

Hi Electocoolman,

Thats exactly what theyre like, the compressor has two round (like kinder egg) shaped pots on top, the fittings for the relays look like three little pins, the relay plugs onto the bottom two pins, a thermal overload goes onto the top pin.

The actual relay is made by Klixon, no other markings (serial No's etc)
The terminals on the relay are numbered 1 and 2, the push on connector part has letters M and S.
Underneath is the gold coloured coil wire.

The compressor was made by a firm called Porter Lancastrian Ltd, Bolton.
Its an old piece of kit, there's a plate on it dated 1972!

Its frustrating that I can't take photos and post so you can see the item!
(Is it possible I could email them or someone host them for me)

Thanks again for the prompt reply and any future help

Kind regards Paul.

Ive tried nike123, but the forum denies users without 15 posts or more from linking to outside URL's.

My photos are on photobucket ready to copy and paste into my topic.

Anyone host a pic for me?

Regards Paul.

I don't know how to say more clear than this:
This is example of link you have for your photos
http://photobucket.com/images/hugs%2...cktype=popular

Then you change it in to this:
photobucket,com/images/hugs%20or%20love/?tracktype=popular

Or something similar.
Every user of this forum with some brain, could then change that to working link if you say that we need to pay attention to that.

Good luck! I cant do more for you then this.

Thanks again nike123, Ive received email off Morgan.
Hes going to post them up for me...but the way Im going Ill have 15 posts under my belt and be able to post them myself.

[Cheekychimpo]

Keep em peeled, pics coming soon.

OK here they are:











P.S. Nike, You are not allowed to post images or links until you have 15 posts under your belt.......

Cheeky,

Before you are replacing the relay, have you checked the windings are OK?

(after you checked the windings out, you could always test run the compressor with the start relay from the other compressor...)

[Cheekychimpo]

Firstly Morgan thanks for posting my images.
Now then, where do I get a replacement start relay from.
The actual compressor pots work,after I hotwired the capacitiors...GULP!

[powell]

You have what's called a current relay. With this compressor being so old I suggest you pick up a solid state relay designed for fractional HP compessors. Here in the US Supco is a very popular product.

[Electrocoolman]

Compressors look like STERNE or NECCHI.

What is value and voltage of capacitors ?

Universal relay up to 1/2hp should do. Where abouts in UK are you.

Have you ever changed the oil in these compressors?

[Cheekychimpo]

Thanks Powell, just read a little about solid state relays on google.
All this is a little new to me, but with the help of the forum members I'm sure I'll crack it.

Right time for sleep, its 1.20am!

Regards Paul.

[Cheekychimpo]

Can try and find some more info on the caps tomorrow Electrocool.Thanks for advice on the compressors.

Im in stoke on trent,staffordshire.

Where would I pick up a "universal relay" from bud??
(I'd feel a right narna walking into maplins and asking for one)

Ive never changed the oil, but the previous owner did,there are details on the back of the compressor about maintenance schedules/oil types.

Thanks again guys
Paul.

(What we need to know capacitor value for is just to confirm whether its a starting cap or run cap...guess its start cap, which will determine type of universal relay to buy)

P.S. Nike, You are not allowed to post images or links until you have 15 posts under your belt.......

I knew that when I posted my advice.

Careful reading will show you that I did not instructed him that he post pictures or link.

I instructed him that he change his links in way that board software doesn't recognize it as links, and that changed links (which is now only string of letters for board software and still usable for intelligent human who made necessary changes to that string) enter in his post.

Example again:
www.the-viking.eu
This string software recognize as link, and mark it in blue, and made hot-link, so you could go there by double-click on it.

Example 2:
ccc,the-viking.eu
This string software recognizes as only string of letters and signs, and doesn't mark them in blue, and don't hot-link them to any web page.

Any person with IQ higher then that of green grass, could then change that string in working link, if that is stated in accompanying description of that "link".

[Cheekychimpo]

Thanks for the links Electrocool.

Im more or less certain its a start cap(only flicks on to actually start the compressor running then disables)

Ill find the info off the cap and give the local suppliers a ring, hopefully they'll be as helpful as you guys.

Soon as its running Ill try a post you a pic.

Thanks guys for sorting my problem out.

Cheers again Electrocoolman

Regards Paul.

[richardb14]

any probs just say, I'm sure I could post one down to you if you get stuck. looks like a necchi compressor to me

[Cheekychimpo]

Thanks for the kind offer Rich, will ring round tomorrow and see if I can track one down, with the advice and info you lot have given me I reckon I have a fighting chance.

If I fail expect a reply!

Thanks everyone, regards Paul.
