LG Range Oven Not Heating or Responding? Main Control Board EBR32401002 – Fix Control Failures Fast
A failed main control board is the most common cause of complete oven failure in LG electric ranges. When the PCB main control board fails, the oven loses the ability to process inputs from the control panel, regulate bake and broil elements, or maintain temperature — leaving the appliance completely unresponsive or stuck in error. ⚡ Common failure point in LG-built electric ranges and slide-in ranges. Part EBR32401002 is the genuine OEM replacement board that restores full oven functionality, element control, and display operation immediately upon installation.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Range powers on but oven does not heat or respond to inputs
- ✔ Bake and broil elements have been tested and confirmed functional
- ✔ Power supply and breaker confirmed OK — 240V reaching the unit
- ✔ Temperature sensor (thermistor) has been tested and reads correctly
- ✔ ONLY problem is loss of control, no heat, or persistent error codes

🔧 Common Symptoms
- Oven completely dead — no heat, no response to any button presses
- Control panel lights up but oven will not start a bake or broil cycle
- Oven shuts off mid-cycle and will not restart
- Display shows F-series error codes (F1, F3, F9, etc.) repeatedly
- Oven temperature wildly inaccurate — burns or undercooks food
- Broil element works but bake element does not, or vice versa
✔ If these symptoms match, the main control board is the most likely failed component in the system.
✔ In most cases, replacing the PCB main control board restores normal oven operation immediately.
📦 Part Details
- Part Number: EBR32401002
- SKU: A025119G
- Type: PCB Main Control Board — genuine OEM electronic control assembly
- Replaces: OEM direct-fit control board — fits all applications originally using EBR32401002 (no modification required)
- Brands: LG, Kenmore (LG-built models)
While the range is open, test the oven temperature sensor (thermistor) — a failing sensor can cause the same symptoms and damage a new control board if left unchecked. Takes 2 minutes with a multimeter and can save a repeat repair.
⚙️ Installation
Skill Level: Moderate — 30 to 45 minutes. Disconnect power at the breaker before beginning — this board carries 240V and must be fully de-energized. Pull the range away from the wall, remove the rear access panel, disconnect the wiring harnesses from the old board, swap the board, and reconnect in reverse order. Ensure all harness clips are fully seated before restoring power.
💡 Pro Tip
Before replacing the control board, test the oven temperature sensor with a multimeter — it should read approximately 1,080–1,090 ohms at room temperature. A shorted or open sensor mimics a dead control board and is a $20 fix vs. $80+. Replacing the board without ruling out the sensor is the most common repeat-repair mistake on LG ranges.
