Lg Range LRE30757SB/00 Element will not heat

This power control board assembly replaces the sub power PCB that manages voltage and signal distribution to the appliance's main controls. Restores control reliability and resolves power-related control issues when the board is at fault. What it does:

• Routes power and control signals between the main control and subsystem components
• Helps the appliance respond correctly to control inputs and cycles
• Commonly replaces a board that causes no power to portions of the appliance or erratic electronic behavior
• Addresses symptoms such as control panel unresponsiveness, intermittent operation, or error codes tied to power/control faults

• Disconnect power before attempting any repair to avoid shock or damage
• Handle the PCB by its edges and avoid static discharge; use proper ESD precautions
• Installation requires basic hand tools and involves removing panels and connectors; keep track of fasteners and wiring
• Replace only with the exact part number to ensure proper fit and function

This radiant surface element mounts beneath the glass cooktop to heat a burner zone on your range. Replacing a failed element restores consistent, responsive heating and reliable temperature control for everyday cooking.

• Provides controlled electric heat under the glass for the selected cooking zone
• Works with the range controls to cycle on/off and maintain the set temperature
• Common symptoms: burner won't heat, heats intermittently or only in spots, or the indicator comes on but the surface stays cold
• Visual clues can include a broken or blistered heating coil visible beneath the glass

• Disconnect power at the breaker and allow the cooktop to cool completely
• Lift/prop the glass top per service procedure; note wiring and bracket locations before removal
• Transfer any brackets/insulators from the old element and make secure, like-for-like connections
• Handle the glass and element carefully; test operation before final reassembly

This radiant surface element mounts beneath the glass cooktop to heat a surface burner. Replace it when a burner won't heat or heats intermittently to restore normal, consistent cooking performance.

• Generates radiant heat under the glass-ceramic top for a surface burner
• Cycles on and off to help maintain the set temperature
• Typical failure signs: no heat, intermittent heat, or visible damage to the element/terminals
• Used on electric ranges and glass cooktops

• Disconnect power at the breaker and allow the cooktop to cool fully before service
• Lift/hinge the glass top and support it to avoid stress or cracks
• Note wire positions; transfer any mounting clips/brackets from the old element to the new
• Ensure the element sits level under the glass and all connections are secure before reassembly

Restore consistent heat to your smooth-top range. This radiant surface element sits beneath the glass-ceramic cooktop and provides the controlled heat needed for boiling, simmering, and sautéing when the surface control sends power. What it does:

• Generates radiant heat beneath the glass cooking surface when energized
• Works with the surface control to reach and maintain the set temperature
• Helps address a burner that won't heat or only heats intermittently
• Replaces a failed or visibly damaged element to restore proper cooking performance

• One radiant surface heating element

• Disconnect power by unplugging the appliance or switching off the circuit breaker before servicing
• Lift and support the glass cooktop per your model's service procedure to access the elements
• Note wire locations; transfer any brackets or clips from the old element to the new one
• Handle carefully and avoid flexing the heating coil; ensure the element sits level before reassembly
