I installed new samsung compressor. I have no wiring diagram to wire the start and run capacitors to relay

Hello;

My name is Peter. I am a retired field service refrigeration technician.

Your problem is not your thermostat. In some models the compressor knocks out the overload relay. They relay could last a few seconds or a few weeks before the compressor knocks it out again. This is especially turn with the LG units.

You will need a multi-meter to check your compressor.

1.) Unplug your unit. Remove the bottom back cover.

2.) Remove the overload components to expose the 3 pins on the compressor.

3.) Inspect the pins on the compressor. Are they clean or are they damaged from heat (Steel melting).

4.) With your multi-meter, set the meter on the lowest Ohms. Read the Ohms between each of the pins. You will have 3 readings. One reading will be high and the other 2 readings will be lower. Add the 2 lower readings together. This value must equal the high reading within a few tenths.

I hope I am wrong. A new compressor depending on the model is $275-$450.00. Include a system filter for $40.00, plus new refrigerant $45.00 and the cost od an experienced technician $300.00.

that sounds like the hardstart relay that energizes the start windings in the compressor . if that or more likely the capacitor fails when it is first energized the compressor will pull excessive amps and cause the overload protector to open until it cools for a minute or two.

A "potential" relay is a voltage controlled start component for the compressor. If your sure the potential relay is bad, not the start capacitor or a seized compressor, Order one from G.E. and replace it.

The wiring diagram for the compressor, start and run caps, potential relay is attached

replace the current relay and overload and start capacitor.
look for any looe or damaged wiring as well.

The start relay should be on the side of the compressor and attached to the three prongs that wiring attaches to on the compressor.Is the problem causing the breaker to trip in the circuit breaker box? Sea Breeze
You can have someone match the start relay and the run capacitor at a refrigeration supply store near you or you can contact Summit

here is a link the manufacture. There is a some information  and manuals posted there. it looks like you may have a something like what they call a 335-935 http://www.caravell.dk/ Their manul at the bottom of all the languages shows a picture of the compressor and the thermostat device and knob. The cooling unit wiring should involve fans, lights and compressor. Compressor will have cutout safety and temp switches as well as the thermostat. and a capacitor. maybe but not likely a relay. It should all be visible around the compressor. Some starting devices may be on the compressor under the plastic cover where the wires go in. If any of those are bad and you do not have a warranty a hard start kit for $18 will replace all the starting components if that is what you need. Let me know if this gets you what you need or have more questions just ask.

The two stripped black wires connect to power.
Black tabbed wire to common.
Red tabbed wire to run.
White tabbed wire to start.
Looking at pins on compressor, read like a clock. Common clockwise to Start clockwise to Run

Your unit is not a self defrosting freezer and consequently has no defrost timer. There are only four components required for cooling in your unit. The temperature control, behind the knob in the cabinet. The compressor at the back bottom. The start relay and overload in a box attached to the compressor. The run capacitor attached to the start relay. A failure of any of those will cause the compressor not to run.

Check the wall outlet to be sure you have power.

If the compressor IS running but not cooling, the compressor itself may be defective or the gas charge may have leaked out. Compressor and refrigeration problems are likely beyond your capabilities in terms of knowledge and equipment.

The temperature control may be tested by all connecting the wires of the control to ONE terminal after unplugging the freezer and marking down teh original locations of the wires. If the compressor runs and cools after this by-pass then change the control and return the wiring to the original locations.

If the above does not make the compressor run the next possibility is changing both the relay/overload assembly AND the run capacitor. If these fail to correct the problem you need a new compressor but you will likely NOT be able to return the parts replaced.

Good Luck

ok you say the compressor sounds right?? there's probably a defective relay overload / start cap combination defective. if you go behind the the fridge and remove a small cover you will see the compressor with power disconnected look for frayed or burnt wires take the compressor cover off and you will see the wires just follow the 3 wires. you can buy a replacement relay/overload capacitor combination all you have to do is wire it any additional questions you can e-mail me at [email protected]

have a nice day
