The Sensor Assembly is an OEM part for LG washing machines. This component is crucial for detecting and monitoring various conditions within the washing machine, such as water level, temperature, and load balance. It ensures the machine operates efficiently and effectively by providing accurate data to the control board.

Causes of a bad sensor assembly can include wear and tear from regular use, exposure to water and detergents, electrical malfunctions, or damage from impact. A faulty sensor assembly can lead to incorrect readings, which can affect the washing machine’s performance and lead to issues such as improper water levels or unbalanced loads.

Symptoms of a bad Sensor Assembly include:

  • Incorrect water levels during cycles
  • The washing machine stopping mid-cycle or not completing cycles
  • Error codes related to water level or load balance
  • The machine failing to start or operate correctly

This OEM LG part is also compatible with Sears/Kenmore models.

Kim for Model Number Wm3987hw

A couple weeks ago I had a problem with my washer during the wash cycle. It would make a grinding style noise and the tub would not spin during the wash cycle. However if I stopped it and did a rinse and spin it worked just fine. Someone suggested I needed to replace the rotary position sensor, so I ordered it from you guys and replaced it but now I have a different problem. Now the machine will go through the wash cycle but once it hits the rinse cycle now it makes the grinding noise the tub will not turn and it will not drain.

Answer

Hello Kim, You should remove the hoses between the outer tub assembly and the drain pump to ensure there are no foreign objects obstructing the pump or preventing draining. I would also closely inspect the inside of the tub for nails, screws, similarly shaped items that can slip through a hole in the spin basket and contact the outer tub. If these are good, turn the spin basket by hand and check that there is no grinding. The motor rotor can be removed and inspected for cracked magnets and/or damages windings.
