Lg Microwave HT902SBR1 Parts

This diode rectifier is the single-direction power diode assembly used in the appliance's high-voltage/power-supply circuit to convert AC to DC and protect downstream electronics. It restores proper power flow for the control system. What it does:

• Converts alternating current from the main supply into direct current used by control electronics.
• Prevents reverse current that can damage sensitive components.
• Commonly linked to symptoms such as a blank display, control board not powering up, blown fuses, or erratic electronic behavior.
• Works as part of the appliance's power supply/rectifier stage and helps stabilize voltage to the control module.

• One diode rectifier as shown.

• Unplug the appliance and disconnect power at the breaker before servicing.
• Discharge any high-voltage capacitors and take ESD precautions when handling electronics.
• Installation typically requires access to the control/power assembly; keep track of wire locations and fasteners.

This diode rectifier converts incoming AC to the DC pulses needed by the inverter circuit so the compressor and inverter board run reliably. Replacing a failed rectifier restores proper power flow for inverter-driven cooling systems. What it does:

• Converts AC power to DC pulses for the inverter/compressor drive
• Helps the inverter board and compressor start and run correctly
• Common symptom when failing: refrigerator not cooling or stopping intermittently
• May cause error codes, frequent cycling, or noisy compressor start attempts

• One diode rectifier assembly

• Disconnect power to the appliance before starting repair
• Handle electronic components carefully and avoid static discharge
• Verify wiring and mounting orientation before reassembly
