Compresser electricals - HELP me please!!!

[pjalchemist]

Okay, this is an aera that still really does confuse the hell out of me. Every unit i've had has all been new and had the stuff there and just plug and go!

The compressers in question are the Mitsubishi horizontal rotary compressor 1/4hp as seen here > http://www.benchtec.co.uk/forums/showthread.php?t=2412

I've searched high and low for info on the compresser with any possible wiring digram or spec finder with no luck. I've even spoken to Gray but thats not helped much!

My problem is i'm missing some of the electicals to wire them up etc etc.

I only got one 3UF cap so i ordered 2 new ones so i'm sorted there.

I got what looks to be one Refrigerator Overload.

I also have what looks like a PTC Relay, run/start cap. Thus im not sure on.

Here are the photos of what i have here, there are some codes on things so i will list them with the photos



^ They are my new 3Uf caps



^ SLEC BF118-JC



^ JUX-045F





^ MZJQ1C-1 100-N-

Now i have one broken MZJQ1C-1 100-N- part, it was broken durling delivery. However this is whats inside of her! Feel like ceramic that small round thing with the codes on





^ TDK H X0-101 7802

Walt kindly posted this in a past topic of mine here of which i'm trying to work out from that how i implerment it to what i have here



There was a sticker thankfully on the compresser and i've taken a photo just incase it's helps matters.



I presume the SCM on the sticker is the same as SCR

So i have 2 of these compresser but one lot of parts that i'm not even sure to how the plug up to the thing. So where do i start, what can i do? Can i build a new set of controls, ie relay, cap etc etc and wire it all up togther then to the compresser?

I am way out of my deepth here and really need some help. Have Googled for as much as i can to get any info on these compressers and mailed loads of people! No avial.

Hope i gave enough info and decent photos. Whom ever strikes gold and make me understand this will be getting some beers i promises.

Read this manual! It will explain most of your questions.
Page 25 and beyond are what you are looking for.

[nike123]

You have condensers, PTC starting devices and overcurrent/overheat relays. Figure 14 at page 28 is your scheme (right part RSCR PTC).

Humm i'm gonna print this off at my mates shop tormorrow in high gloss and then make his misses laminate it then i will studdy it more! Thank you for this.

However i still have issue i am missing 2 parts to do it!

You should find PTC starting device according to data of compressor from any manufacturer of such device available to your place.

Check this!

Also, condenser is available in any store with parts for white goods.

These PTC on your pictures are probably Chinese made and their data are not available on net.

[Peter_1]

Sorry but this is a very basic schematic of a PTC started /Cap assisted compressor.

[Peter_1]

Only difference I see is a potential relay on the schematic where you have a PTC relay.
The round thing in it is a small heating element which changes in resistance when a current is drawn through it.

[pjalchemist]

Condesner i have. Just need the electricals for it and how to wire them up.

Still am confused to how to do this!!

Would some one be willing to grab me the parts, wire it up (i'll send you my caps as well) and i'll pay for the parts and your time!

[nike123]

Sorry, I cannot do more easier than this.


This is data for one of compressor protection!

I duno where to begin but thank you! I think i get it now looking at varying drawings and these!

Just to conferm, condenser you are refering to the fan?

One thing im still confused of, where does the 3UF cap fit in?

I mailed the company about the compressor protection asking where i can get 2 from.

Still need to find 2 new PTC devices as i have one which i think might be broken so need to get 2 new ones.

Both compresser are going in the same system so need 2 of each part but still having no luck in finding them!

[nike123]

No, fan is connected at thermostat!
By condenser, I here mean 3uf capacitor.
Here we say "kondenzator" which is simmilar as condenser and therefore my use of this therm.

Quote from Wikipedia:

Capacitor, formerly called a condenser, an electrical device that can store energy.

Wow you really do learn somethign daily. Think i got it now! Just need to parts

[pjalchemist]

Okay i got how it all goes togther, now to get hold of the new parts which i am not having much luck with it at all sadly.

[icecube51]

we in Belgium try to stay by the meaning "capacitor" , the word conden-sor or -sator is to confiusing in the refrigaration branche.
just kidding,

I gave you, in my answers, some data to work with in order to get replacement parts. Please, read carefully links I posted, and if you don't know how to use them, ask here in details.

[sedgy]

ave you got an a-c unit you can test and coppy?on site

Okay i don't know how too go about using the links you gave me too obtain the parts i need

For motor protection you can use any with same operating temperature range and tolerance (in your case that is 97°C range and 7°C tolerance). Also, you need to take care about rated amperage for, but for that small compressor, any for domestic refrigeration could probably be used.

For starting PTC device you should calculate data required on page 4 of manual I already linked, or prepare required data, and ask for help at contact telephones at that page.


Or, you could use this combined PTC starter and protection.
For details contact number is on last page.

Im in the uk, last time i spoke to an amaerican we had a massive fight and he was booted out the Army!

I've no idea at all where to find these parts

Try a refrigeration or air conditioning wholesaler.

HRP, Climate Center, SWM, Dean & Wood...

[nike123]

You should also develop simple skill "how to find representatives and distributors" by searching contacts at manufacturers web pages.

Im looking but still not seeing the parts i am after at all what so ever

[FreezerGeezer]

Best ring the suppliers then, & talk to someone technical there. They should be able to help you out with the parts.

Did you called that numbers I gave you?

Compresser is no longer made by all account and was back in the 90's. I got them off Ebay

Did you called that numbers I gave you?

No answer the 3 times i called

[pjalchemist]

Tried calling a few places today but with no luck at all what so ever

[pjalchemist]

Think i might have a lead at long last

[JDR Cool]

are you a fridge engineer or not? This is pretty basic stuff - you will be able to buy a set of electrics for this compressor from any decent wholesaler - and the actual wiring is one of the first things you learn!!
Hope you never come across a burnt out panel in a 20year old supermarket at 3 in the morning with no wiring diagrams!!!

Never said i was did i! Most of the companies i have spoken or found only deal with you if you have an account with them

[JDR Cool]

so if you are not a fridge engineer, why are you working on a fridge compressor that you have no knowledge of?? As the old saying goes "A LITTLE NOWLEDGE IS DANGEROUS"
Thought this site was for fridge guys!!

If you follow the threads relating to the type of product that PJ is trying to make then you would perhaps understand why he, like a lot of others, are working with these small compressors.

Also; no, this site is for anyone who is interested in the subject or has a related question to ask.

You seem to be coming in a bit strong for your first two posts on this forum, should we be standing in awe of you or shall we wait until we've been introduced ?

Once again thanks Brian, you are so much more politically correct than I would have been, but I guess you have to be..

[pjalchemist]

Sad too see the bug of being so polictly correct and stuck is amoung us still!

I can do it all no problems there as the info is all over the net and spoken too many that do it and have done a bit my self but my problem is getting hold of electrical parts.

[Brian_UK]

Just a thought, is it worth going to your local fridge recycling centre to see if you can grab some parts off of the old units ?

Perhaps get a selection ?

edit: Thanks NH3, you should have seen the draft version

Nothing like that around the Bristol area that i can find. Also with what info i found on these there from the 90s

[Brian_UK]

PJ, have you tried Climate Center for your electrical parts yet ?

Just been looking and they got stuff listed for PTC and Overload but i have no idea what i am exactly looking for there as parts are going too be different on the codes.

I've mailed them but had no reply, been 4 days so far!

It looks like the place too get what i am after but i have no idea whats there that i need off them!

[Brian_UK]

You can get universal kits I believe so maybe that is the way to go.

A visit to the store would beat an email I suspect, the guys there do not always know a lot more than the guy buying from them.

Ah right, can't really afford any time away from the pub, just sacked my assitant manager so im stuck there every day pretty much!

Just to be able too mail order or pay someone for the parts be wicked and simple
