let me explain my problem :
I already discovered in the compressor which pins are the comon, start and run and I pluged these three wires that come in the supco on them.
I`m having problem to identify how to plug the other two wires that come on supco.
Supco´s instructions told me to get of the old relay and to install the new relay on the two wires that enter in the old relay. The problem is thar my relay has 3 wires on it. one came from inside the refrigerator and the other two was wired on the star and run pins of the compressor.
I let the oold relay on its place and I followed the power cord under the refrigerator and I pluged the supco´s two wire direct on it and the refrigerator works ok, but the thermostarter is not working.
I think that the wire that I let on the old relay was for the thermostarter and I don´t know how to identify and instal it on the new relay.
Sorry about my bad english
Don´t worry about colors. The refrigerator is very old and all wires now are white.
I have 3 wires that come out of the refrigerator. One is wired to the common, other is wired to ne neutral and the other was wired to the old relay.
I have 3 wires coming of the refrigerator. One is wired to the common, other is wired on the neutral and the last is wired in the old relay.
I pluged the new relay together with the wires that were pluged in the common and neutral. How to plug the wire that is in the old relay? Should I wire it with the common or with the neutral?
How to identify on these 3 wires that came from inside which one is for the light and wich is for the thermostat?
I´m out of town. I will send you the picture at night. I will also try to draw how the refrigerator was wired.
Only to make things clear, I have 3 wires coming out of refrigerator. I supose that these wires are for light and thermostat. How to identify and how to wire correct these wires in the new relay and with neutral and common wires that came from power plug.
Sorry about the stupid question, but can you explain me how to measure voltage to discover how to identify and wire these three wires? Should I turn the refrigerator on or should i take the measure with the refrigerator off like I made to discover the common, run and start plug in the compressor?
I will be out of town until friday. I won´t be able to send you the picture today as I said, but I used my memory to draw the old and the new wire diagrams.
In the new one you can see that I have a wire in the old relay that i need to connect in the new relay, but I don´t know where.
I don´t know if you received my last reply.
How to know what wire is the hot line? Is it the one that was connected to the compressor´s common plug in the first diagram?
If I undestood right, the hot line will enter in the refrigerator and then it will came back in the old relay´s wire and it shoul be connected to the supco´s wire. The other supco´s wire will be connect to the other wire that come from the power plug that should be the neutral wire.
Am I right?
Is there a way to check these wire to avoid damage my refrigerator? what will happen if I connected something wrong? The refrigerator will not work or can I burn something?
I will try your suggestion when I arrive home on Friday.
I will let you know if the thermostat and the refrigerator will work fine.
Thank you very much for all your pacience with my questions.
I draw a new diagram with my undestood of yourr explanation. Please check if it is right.
My only doubt is about my first diagram. The wire that come from power cord and was connected directed to the compressor´s common plug I think that was the neutral, because the hot line will came from the old relay and will power the run and start plug. Am I right?
Here ins Brazil the power cord has two similar legs in the power plug and it can be connected to eletricity in one position or you can turn it 180º and connected it in the upside down position. When you do that, the wire that was the hot line became the neutral and the neutral wire become the hot line. Does this situation matter in my connections or this is the normal situation for any eletric device? I know that in USA the power plug can only be connected in one position, because the legs in the power plug are differents.
I found the original wiring diagram. I think that will be easier to talk over this diagram.
So, In this diagram, the connection with the number "1" is the hot line and the wire with the letter "L" in the YT relay should be connect to the supco and the other supco´s wire should be connected in the number "2" connection, that will be the neutral. Am I right?
These are exactly the "L" and the number "2" that I mensioned on my reply. I will try these wiring tonight and I will let you know if it works.
Ok. I undestood about compressor pressure equalization, but how about the very audible hummmm noise?
Ok. If I am undestanding right, the noise is normal, ok?
Only too check I measure the compressor with a ohm meter. I have the follow result :
With thiss results I identify the A as the common, B as start and C as run. Am I right?
My compressor has the letters R 1/8-16 printed in it. I have two supco´s relays, the HS810 and the RCO410. Wich one is the best for my compressor?
Thanks for all your help.
Here is my last question : the hummm noise will not cause any damage to my refrigerator and it will remains until the thermostat send a signal to start it again and your pressure has been equalized. Am I right?
I was afraid that the hummm could damage the compressor, because I´ve never heard this noise in my refrigerator before.
