Parts for Lg LW1800PR: Cabinet 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

This remote controller assembly is the complete handheld control used to operate compatible appliances, restoring lost or damaged remote control functions for convenient, wireless operation. What it does:

• Sends the appliance's infrared/remote commands to control settings and cycles
• Replaces a broken, unresponsive, or missing remote to regain full remote functionality
• Helps resolve symptoms like no response from remote, intermittent command reception, or damaged buttons
• Works as the user-facing control interface for selecting modes, temperatures, or timed functions

• One remote controller assembly (as shown)

• Replace with the power source removed and follow the appliance manual for pairing or setup
• Handle electronic components carefully; avoid moisture and static discharge
• If the original remote used batteries, install fresh batteries and test operation after replacement
• If commands still fail, verify line-of-sight to the appliance and that the appliance receiver is powered

This clamp secures a line or connection inside your appliance, maintaining a tight fit under vibration. Replacing a fatigued clamp helps prevent leaks or disconnections and keeps components anchored so the system operates reliably.

• Holds a line/fitting firmly to keep the joint sealed and secure
• Helps prevent leaks or disconnections at hose/tube connections
• Resists vibration that can loosen fittings during operation
• Replace if bent, weakened, or corroded, or if the connection repeatedly loosens

• Disconnect power and, if applicable, shut off water supply before service
• Note clamp orientation and routing; seat the clamp just behind the fitting bead/stop
• Use the correct tool for your clamp style to compress or tighten evenly
• After reassembly, restore utilities and test for leaks or movement

This electric capacitor is a direct-replacement appliance capacitor used to support motor start/run circuits and stable electrical performance. Installing the correct capacitor restores reliable motor operation and reduces start-up issues. What it does:

• Provides the stored electrical charge needed for motor start and run cycles
• Stabilizes voltage to help motors and control boards operate correctly
• Symptoms of a failing capacitor: humming motors, motors that won't start or run intermittently, or reduced performance
• Commonly used in appliance motor and compressor circuits

• Disconnect power to the appliance before accessing electrical components
• Discharge the capacitor safely before touching terminals to avoid shock
• Match capacitance and voltage ratings from the original part
