Default LG PTC or Overload Protect?
Model Number: LSC27931ST   Brand: -other-   Age: 1 - 5 years   

Appliance Parts from AppliancePartPros.com


I am having a problem with my refrigerator not cooling, fan working, and compressor hot but not working. I found a thread on here that helped me test the compressor and both windings read within normal range. The person in the thread said that if these were within normal range, then it was the relay overload that was bad. My problem is that when looking at the parts diagram, I don't see an option for relay overload. I see a part called PTC Thermistor Assembly and a part called Overload Protect. Which of these is the part that I need to replace?

I am not sure exactly what these parts look like because there is no image available for them. The parts from my fridge are a grey plastic piece that is irregular shaped with a guide arm type appendage on it(i'm guessing this is overload protect) and a black rectangular block with two prongs that plug into the grey piece(i'm guessing this is the PTC Thermistor Assembly). Any help with picking out which part is the part that I need to replace would be greatly greatly appreciated.

You ever fix the problem? Same fridge and same problem. Can't find a replacement relay.

Check your schematic, might be a 3 phase compressor controlled by the main relay board.

Thanks for the reply. I'm assuming it is not. It is an Embraco EGX 90HLC. I have purchased a whirlpool relay that looks very similar that should be coming in today. Think I should be checking out the pcb as well?

You have to be careful, if you use the wrong relay, you will burn out your compressor! I hope you saved your old start device.

I did, I purchased a relay kit with a few parts in it with the instructions stating use for embraco egy 80 and 90 model compressors. Think I should look for something else?

Is the start device recommended for your model refrigerator, if not, I would not use it.

I appreciate your feedback. I purchased Whirlpool W10189190 which is almost identical. They are both made by Embraco and have the same ratings on the label. The only difference is that the pins at the top of the relay were more narrow than the original. What I did was open the relays for both and looked at the pcb inside. They are both identical, all the way down to the numbers printed on the board and all the soldering points on the pcb. I removed the PCB from the new and placed it in the old one with the old pins so they fit the wires. While I don't like having to use different parts that are not recommended, I had no choice since the part is no longer in production. I am pretty confident that the relay is the exact same relay.

I checked the start device, you are good to go, looks like it's impossible to burn out the compressor if wired internally like the old one.

I appreciate all your feedback. I didnt mention it in the previous post, but the fridge runs fine now, just in case anyone runs into the same problem with this refrigerator.
