Customer Questions and Answers for Temperature Sensor by Lg

Manufacturer Part Number: ACQ73244001

The Temperature Sensor is an OEM part for LG refrigerators, designed to monitor and relay the temperature inside the refrigerator to the control board. This component ensures that your refrigerator maintains the correct temperature to keep your food fresh and safe to eat. 

Over time, temperature sensors can fail or become less accurate due to wear and tear, environmental factors, or electrical issues. This can lead to problems such as the refrigerator cooling too much or not enough, resulting in food spoilage or excessive energy consumption.

Symptoms of a bad Temperature Sensor include:

  • The refrigerator or freezer is too warm or too cold, despite setting adjustments
  • Unusual fluctuations in temperature, indicating the sensor is not accurately detecting or communicating the internal temperature
  • The refrigerator runs constantly or more frequently than normal, attempting to reach the desired temperature

This OEM LG part is also compatible with some Kenmore models.

Questions & Answers

For Lg Temperature Sensor (Part Number: OEM14012289)

1 Answer

Terry, the condenser coils near the compressor would need to be cleaned. If they are clean, the next step would be identifying if the condenser fan and compressor are operating. If they are, the evaporator coils will need to be inspected for ice build-up that could be preventing airflow. If there is not ice build-up or if there is no frost pattern, there is likely a sealed system failure that would require an EPA-certified technician to diagnose and repair the failure.

Tom, Based on the information provided this does sound like a sealed system issue therefore you will need an EPA-certified technician for these repairs.

Malik for Model Number LFXS30766S

Hi... my freezer is working fine but refrigerator does not. We've it set to 33 but its not hitting that temp but fluctuates between 41-50. I checked if coil was iced but nope. Refrigerator fan is also running with no issue. My issue may be temperature sensor and looking to replace but not sure which one is it. I see one sensor i.e. ACQ73244001 in vegetable drawer but another one i.e 6500JB2001B with led light. Can you please explain how the 2 are different and which one should i replaced.

Mike C for Model Number 79571036010

Hello - Is Temperature Sensor Part No. ACQ73244001 the same as Temperature Sensor Part No. 6500JB2001B without the cover? The descriptions are confusing to me. My refrigerator and freezer are not cooling / freezing. I removed temperature sensor ACQ73244001from the freezer compartment area. The resistance measures 2.5K Ohms at room temperature and 7.65K Ohms in ice water...what are the normal readings for ACQ73244001? If sensor 6500JB2001B is different, where is that located and what should the resistance be? Thank you!

1 Answer

Mike C, as a rule of thumb the sensors all have the same resistances but have different length wires and connectors often. Either sensor can work as long as you can connect it (splice/plug in).

Chuck, the fans would need to be inspected when the door switches are being manually activated as the fans will not operate unless the switches are in the closed positions. If they do not operate this way, the main control EBR79267107 would be the likely cause of failure. If they do start to operate this way, the frost pattern on the evaporators would need to be inspected as there should be a light even coating of frost across the entire evaporator. If there is not an even coating of frost, there would likely be a sealed system failure if the condenser coils are clean. If this is the case, an EPA-certified technician would be needed for diagnosing and repairing this unit.

Doug S for Model Number 79571053010

My refrigerator is cold but the freezer in not. There is no frost on the coils and they are clean. The fan by the compressor is working and there is cold air blowing into the refrigerator, the freezer and the ice maker. The PCBs all look fine with no smell or sign of burning. Ran the tests with the test button and and everything is working. Also the LED on the board is not flashing with error codes. Could the problem be the temperature sensor?

1 Answer

Doug S., Thanks for the question!!! If there is no frost on the coils and the compressor is running then you would have a sealed system issue and will need an EPA certified technician.

Rich for Model Number LMX30995ST

HI There, Hope all is well! I am having an issue with my LG model LMX30995ST- Just turned 7 years old- replaced Compressor last year this time, New issue in the frig compartment, the temp fluctuates from 33 to 50 degrees F when it is set at 34 in the fridge section. The freezer section seems to be ok and is around 5 degrees F. I was thinking it was the refrigerator compartment sensor that could be the issue, but I could not locate it physically. Any help would be appreciated. Please help if you can. Thanks and have a good day, Rich
