LG Oven/stove Repair – North Canton, OH (LRG3085ST)

A customer in North Canton called about their LG gas range that wouldn’t heat up. Neither the broiler nor oven would preheat, and both generated an F-9 error code that persisted even after unplugging the unit. We found the main control board had completely failed.

The Problem

The customer reported that neither the broiler nor oven would preheat. Both generated an F-9 error code. They unplugged the oven for 10 minutes to see if the electronics would reset, but it still generated an F-9 code. The stove burners all worked OK.

Diagnosis

The F-9 error code on this LG range indicated a main control board failure. With the burners still functioning normally, this confirmed the issue was isolated to the oven’s electronic control system rather than a broader electrical problem.

The Repair

• Parts replaced: EBR73811706 — PCB Assembly – Main
• Work performed: Replaced the main control board
• Result: The stove is operating correctly

Is It Worth Repairing?

LG ranges are generally well-built appliances with good longevity. A main control board replacement on a unit like this LRG3085ST is typically worthwhile, especially when the rest of the appliance functions properly. These ranges often provide many more years of reliable service after this type of repair.

Maintenance Tips for LG Ovens/Stoves

• Keep the control panel clean and dry — moisture can damage electronic components over time
• Use the self-cleaning cycle sparingly on LG ovens, as excessive heat can stress control boards
• Ensure proper ventilation around the unit to prevent overheating of internal electronics
