Ls19901a0 Parts

The Blower Wheel Bearing is an OEM part for LG air conditioners. This bearing supports the blower wheel, ensuring smooth rotation and efficient airflow throughout the unit. 

Causes of a bad blower wheel bearing can include wear and tear from regular use, lack of lubrication, or damage from debris or impact. 

Symptoms of a bad blower wheel bearing include:

• Unusual grinding or squealing noises from the blower area
• Reduced airflow or diminished cooling efficiency
• The blower wheel wobbling or vibrating excessively
• The fan motor struggling to start or run smoothly

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

This replacement remote control restores convenient, across-the-room operation of your air conditioner. Replace a lost, damaged, or unresponsive remote to regain reliable control of power, temperature, and modes without touching the unit.

• Sends commands to the air conditioner's receiver to adjust power, temperature, mode, and fan settings
• Common fix for no response to button presses, intermittent control, or needing to stand very close to the unit
• Restores normal operation when the original remote is lost, cracked, or has worn-out buttons

• Install fresh batteries with correct polarity (+/-)
• Aim the remote at the unit's receiver with a clear line of sight; remove obstructions
• If the unit does not respond, replace batteries and power-cycle the A/C before further diagnosis

Replacement electric motor used in select LG appliances to restore motor-driven functions. Replaces failed or noisy motors to help return normal operation, reduce unusual noise, and restore rotation or airflow where applicable. What it does:

• Provides rotational power to drive appliance components such as drums, impellers or agitators.
• Common symptom indicators: appliance won't rotate, motor hums but won't start, excessive grinding/vibration, or noticeably reduced airflow.
• Re-establishes mechanical motion when the original motor has failed or developed bearing/windings issues.
• Connects to the existing wiring harness and mounts in the original motor bracket.

• Disconnect power before servicing; verify the appliance is fully de-energized.
• Label or photograph wiring and harness connectors before disconnecting to ensure correct re-assembly.
• Use appropriate tools and secure all fasteners; inspect related components (belts, mounts, ducting) during replacement.

This isolator routes microwave energy between the magnetron and waveguide to help protect components and maintain consistent heating performance. Replacing a failed isolator can restore reliable cooking and help prevent further high-voltage damage. What it does:

• Directs RF energy from the magnetron into the waveguide/cavity
• Helps protect the magnetron by reducing reflected energy
• Aids in preventing arcing or burn damage in the waveguide area
• Common symptoms of failure: no heat or uneven heating, loud humming/buzzing, visible arcing/burn marks near the waveguide

• 1 isolator

• Disconnect power and discharge the high-voltage capacitor before servicing; risk of electric shock
• Handle waveguide components carefully; avoid contaminating RF surfaces and note exact orientation
• Take photos of the original setup to match positioning and fastener locations

This fan propeller assembly circulates cold air inside the refrigerator to help maintain even temperatures and proper airflow. Replacing a worn or broken propeller restores circulation and can stop abnormal noises. What it does:

• Moves air across the evaporator and throughout the fresh-food compartment for consistent cooling
• Restores airflow reduced by cracked or missing blades
• Stops scraping, rattling, or high-pitched fan noises caused by damaged propeller blades
• Helps prevent uneven cooling and localized warm spots when operating correctly

• One fan propeller assembly

• Unplug the appliance before starting any repair to avoid electrical shock
• Handle blades carefully to avoid bending or cracking; a damaged blade will cause vibration
• Verify mounting orientation and secure fasteners; check that the motor shaft and hub seat properly

This DC stepping motor assembly drives precise, incremental movement in the appliance's subsystem to restore correct mechanical positioning and timing. Replacing a failed stepping motor brings back accurate, repeatable motion and reduces related errors. What it does:

• Converts electrical signals into precise, step-wise rotation for controlled mechanical movement
• Restores accurate positioning when the appliance stops mid-cycle or fails to advance
• Can stop intermittent operation, humming, or lack of movement caused by a faulty motor
• Clears related error codes or cycle faults that point to motor or position problems

• One complete DC stepping motor assembly

• Disconnect power before servicing to avoid shock or short circuits
• Verify the motor harness connector and orientation before removal and reinstallation
• Handle the motor and gear interfaces carefully to avoid damage to mating parts

This NTC thermistor assembly senses internal temperature and delivers accurate readings to the appliance control so the system maintains proper cooling. Replaces a failed sensor to restore reliable temperature feedback. What it does

• Monitors evaporator/compartment temperature and sends a resistance-based signal to the control board
• Helps the control maintain correct cooling cycles and defrost timing
• Common symptom: incorrect or fluctuating temperatures inside the appliance
• Common symptom: appliance runs continuously or won't cool properly
• Common symptom: temperature-related error codes or diagnostics pointing to a sensor fault

• Disconnect power before servicing to avoid shock or injury
• Handle the sensor and wiring gently; do not stretch or pinch the harness
• Verify the new assembly matches the original mounting and connector before installing
• Test the sensor with a multimeter (resistance vs. temperature)

The Propeller Fan Assembly is an OEM part for LG window air conditioners. As the primary cooling component, the fan assembly endures constant rotation circulating air throughout interior spaces.

Causes of a damaged fan assembly can include bearing deterioration over extended run times. Foreign object contact or abrasion may also degrade protective coatings prematurely.

Symptoms of a bad Propeller Fan Assembly include:

• Abnormal vibration or noise during operation
• Reduced airflow throwing capacity
• Inability to maintain consistent temperature control
• Premature motor or electronics failure from excess stress

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

This electric capacitor is a replacement start/run capacitor that helps the motor start and run smoothly. Replacing a failing capacitor restores normal motor operation and can stop humming, no-start, or intermittent run issues. What it does:

• Provides the phase shift and stored energy needed for motor startup and stable operation
• Commonly replaced when a motor hesitates to start, hums without turning, or runs inconsistently
• Helps protect the compressor/motor from stress caused by weak or failed capacitors
• Matches the original electrical function for systems designed for this capacitor type

• One electric capacitor (Capacitor, electric A) — only the part listed

• Disconnect power to the appliance before starting any work
• Capacitors can hold charge; discharge safely before touching terminals or wiring
• Verify terminal orientation and secure mounting; replace only with the correct part number
