Do-It-Yourself Stories from Customers like You Lower freezer door would not stay shut turns out a shaft with gears was missing from initial install   Bruce M. • New River , AZ • August 08, 2016

Ordered the parts, which was a pair of ice gears and the bar that connects them. Had to refer to upper freezer drawer to figure out how the gears fit into the rails. Turns out they snap into a plastic hub that is riveted on the rail. Took some effort to finally get them to snap on. At first it seemed like they would not fit. Really had to apply force to get them to go on. Then added bar, which seems to me to be slightly short in length. It works, but I think if any tension is put on it,... Read more

Temperature Sensor (Refrigerator)
Genuine Lg part
By: Lg
Part Number: 6500JB1001K

This temperature sensor is the thermistor that monitors compartment temperature and reports it to the control. Replacing a failed sensor helps restore accurate cooling and steady, reliable temperatures in your refrigerator.

  • Helps the control regulate compressor, evaporator fan, and air damper operation
  • Also called a thermistor; critical for maintaining stable, set-point temperatures
  • Failure symptoms can include sections that are too warm or too cold, erratic temperature swings, or frequent cycling
What's included: One temperature sensor (thermistor) assembly Install notes:
  • Unplug the refrigerator before servicing
  • Access location varies by model (often behind an interior cover or air duct); note routing and placement before removal

Ptc Thermistor Assembly (Sensor)
Genuine Lg part
By: Lg
Part Number: EBG62325702

This PTC thermistor assembly feeds temperature feedback to the control so the appliance can monitor conditions and run sensor-based cycles correctly. Replacing a failed sensor restores reliable automatic operation and prevents errors that lead to inconsistent results.

  • In some models, a bad sensor may prevent sensor modes from starting
What's included: One PTC thermistor assembly. Install notes:
  • Disconnect power before servicing; microwaves can retain dangerous high voltage—discharge the capacitor before touching internal components
  • Access and mounting location vary by model; commonly found behind the grille or near the control in the air duct path
  • Route the harness exactly as original; keep wiring away from sharp edges and hot areas
  • Avoid touching the sensing tip; ensure all connectors are fully seated
