Parts for Lg LA090CP / AMTAEUS: Section 2 Parts

Replace a failed air conditioner motor assembly when your unit won't cool or the fan doesn't spin. Direct fit part for room AC units. DIY repair.

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

Replace your air conditioner's propeller fan assembly if the original is cracked, broken, or has damaged blades. Installs inside the unit housing.

Fix an air conditioner that won't start or keeps shutting off with this overload protector. Protects compressor from damage. Moderate DIY repair.
