  • Common symptoms a bad relay may cause: compressor clicking, humming without starting, intermittent cooling or frequent cycling.
  • Installed as the electrical component used only on compatible compressor assemblies.
What's included Includes one start relay. Install notes
  • Disconnect power to the appliance before servicing to avoid electrical shock.
  • Access the relay at the compressor; remove and replace the relay only after confirming diagnostics.

Do-It-Yourself Stories from Customers like You Compressor not running.   Eric A. • Canton , MA • December 16, 2017

My freezer and fridge were blowing warm and all my food in there was garbage... Lights and fans all working. Looked up some YouTube videos on what it could be. Bad compressor least likely culprit even though it wasn't running. It wasn't doing that "click whirr" thing if it were trying to start. It just flat out wasn't running. So, check the overload and relay that attach right on the side of the compressor. I did, and I shook them. They jingled like loose change=BAD. Ordered new ones and... Read more

Do-It-Yourself Stories from Customers like You Lg refrigerator compressor would intermittantly hum and shut down but then start normally minutes later   Don C. • Pearland , TX • July 23, 2016

After watching repair videos, I decided I could order the parts needed and do it myself for less than a service call, not to mention the additional cost for parts markup and installation that a service technician would charge. I am very pleased that I did. I ordered the start relay, overload and capacitor with some help from Ilya at customer service to make sure I was getting the correct replacements. Installation was easy. The hardest thing was contorting my body into a position where I could... Read more

  • Protects the refrigerator compressor from overheating and electrical overloads
  • Works with the compressor start relay to help the motor start and run properly
  • Common symptom linkage: replaces a failed overload when the compressor hums but won't start
  • Stops compressor cycling or prevents repeated trips that cause cooling loss
What's included:
  • One compressor overload (single piece as shown)
Install notes:
  • Disconnect all power before replacing to avoid shock or injury
  • Handle terminals carefully and reconnect matching terminal positions
  • Replace only with the same part number or equivalent
  • If compressor still won't start after replacing the overload, check the start relay and compressor condition.

Do-It-Yourself Stories from Customers like You Ice maker quit working.   Lee H. • Cleveland , MN • June 04, 2020

This was easier then I made it. Originally took the actual ice maker out without removing the whole system from the door. There are 3 silver screws that do that hold the whole mechanism in place, as opposed to the 5 white screws that hold the ice maker in place. With the entire assembly out it was a matter of routing the ground wire, retaping the wires, and then the whole assembly went back into the door without a problem.
