Parts for Lg LA180CP / AMTAEUS: Section 2 Parts

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

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.
