LG Oven Not Heating or Controls Unresponsive? Main Control Board EBR74164812 – Fix It Fast
When your LG oven won't heat, displays error codes, or the touchpad stops responding, the main control board is the most common cause. In most LG LRE-series electric ranges, this is caused by a failed PCB assembly. When it fails, the oven may not heat at all, bake and broil elements may stop responding, or the display may go blank or show fault codes. ⚡ Common failure point in LG-built electric ranges. Part EBR74164812 is the genuine OEM replacement that restores full oven control and heating function.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Your range powers on and the clock or display shows activity
- ✔ The oven door, light, and surface burners work correctly
- ✔ Household circuit breaker and outlet voltage confirmed OK
- ✔ ONLY problem is oven not heating, unresponsive controls, or persistent error codes

🔧 Common Symptoms
- Oven will not heat on bake or broil
- Touchpad or control panel is unresponsive or erratic
- Display shows F-series error codes (F1, F3, F7, etc.)
- Oven shuts off mid-cycle or fails to maintain temperature
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this control board restores normal oven operation immediately.

⚠️ Recommended While Repairing:
Check the oven temperature sensor (EBG61106803 or compatible) while the range is open — a failed sensor is often misdiagnosed as a board failure and costs a fraction of the board. Replace both if the sensor reads outside 1080–1090Ω at room temperature.

⚙️ Installation
Skill Level: Moderate — 30–45 minutes. Disconnect power before servicing. Pull the range away from the wall, remove the rear access panel, disconnect the wiring harness connectors from the old board, transfer the board to the new assembly, and reconnect. No soldering required — all connectors are plug-and-play.

💡 Pro Tip
Order the Sensor at the Same Time:
If your board has been running with a faulty temperature sensor, the sensor's out-of-range resistance readings may have contributed to board stress. Replacing the temperature sensor alongside the control board is the most reliable path to a lasting repair — and saves a second service call if the sensor fails shortly after.
