Customer Questions and Answers for Main Pcb Power Control Board Assembly by Lg

The Main PCB Assembly is an OEM replacement part for LG dryers. As the central electronic control center, it oversees functions like temperature selection, timed cycles, sensors that detect moisture levels, and activation of components such as the drum motor, heating element, and fan. 

Causes of a bad main PCB can include exposure to moisture inside the dryer from vent problems or spilled loads. Electrical damage from power surges is also possible. Normal wear contributes to extended use.

Symptoms of a bad main PCB include:

• The dryer failing to power on or start cycles  
• Inability to select the temperature, cycle type, or time settings
• Drum not rotating or heating element not activating
• Abnormal buzzing or humming noises arising  
• Frequent trips of the thermal fuse

It extends the appliance lifespan and is also compatible with Sears/Kenmore dryers.
