Lg Range LRE30451SW003 Little to no heat when broiling

The PCB Assembly is an OEM component for LG ranges. It is the circuit board responsible for controlling critical range functions such as the oven, cooking elements, and display. 

Symptoms of a bad PCB assembly can include: 

• Range elements not working properly 
• Display malfunctions or failures 
• Improper functioning of oven features like bake, broil, and convection modes 

Causes of a bad circuit board tend to be normal wear and tear over time from heavy usage and heat exposure during cooking. Occasional power surges or fluctuations can also potentially cause circuit damage. 

This OEM LG part is also compatible with Sears/Kenmore.

Replacement sub printed circuit board that restores the appliance's electronic control functions by processing and routing signals between the user interface and other control modules, helping address unresponsive controls and erratic operation. What it does:

• Processes and routes control signals between the user interface and main control modules.
• Replaces a failed sub control board that can cause unresponsive buttons, blank or flickering displays, or intermittent operation.
• Can resolve specific feature failures or error codes tied to the sub board circuitry.
• Provides a direct OEM-design replacement to restore proper electronic control when the original board is faulty.

• Disconnect power to the appliance before accessing electrical components.
• Document or photograph connector locations before removal to ensure correct reassembly.
• Handle the board by the edges and use proper ESD precautions to avoid damage.
