LG Range/Stove/Oven Display Board Replacement

LG Range Control Board & Display Board Failures

An LG range control board (also called an ERC or clock board) runs every heating cycle, temperature regulation, and safety interlock. When yours shows error codes, won't respond to button presses, or the display goes dark — the control board is almost always the culprit. Temperature sensors feed data to the board; the board commands the igniter, bake element, or broil element to heat. A failed board means no bake, no broil, and a dead timer display.

Display boards on LG ranges are integrated into the main ERC in most models. If your oven won't heat but the stovetop works, or buttons are unresponsive while the display flickers, an OEM replacement board restores full function. Enter your LG model number below to find the exact circuit board for your range.

• No response to button presses: display dead or frozen; control board has failed
• Error codes or blinking lights: board detected a problem; replace board or sensor based on error
• Oven won't heat but stovetop works: bake/broil circuit on board may be open
• Temperature runs too hot or too cold: temperature sensor or board calibration issue
• Timer and clock display won't update: display board circuitry failure

LG Range Control & Display Board FAQs

What's the difference between an ERC and a display board on an LG range?

The ERC (Electronic Range Control) is the main circuit board — it processes all heating commands, temperature readings, and safety functions. The display board is typically integrated into the ERC on LG ranges; they're one assembly. Some models have a separate touchpad or clock display that connects to the main ERC via ribbon cable. Always use your exact model number to confirm whether your range has one board or two. Aftermarket or mismatched boards won't communicate correctly with LG's ignition and sensor systems.

How do I find my LG range model number?

The model number is printed on a label inside the oven cavity (left or right wall) or on the back of the range. It starts with LSMV, LSRG, LRGL, or LRSC followed by numbers. You can also check your original paperwork or warranty card. Once you have it, enter it into Repair Clinic's parts lookup tool to confirm the exact board for your model — LG has many variants, and the wrong board won't fit or function.

Will an LG range control board from a different model fit mine?

No. LG range boards are model-specific. Even ranges in the same series (like LRG3095 vs. LRG3195) use different boards. Using the wrong board can damage your igniter circuit, fail to recognize your sensors, or not fit the mounting brackets. Always verify your model number in the parts lookup before ordering. OEM boards come programmed for your specific range's heating elements, safety sensors, and ignition timing.

What's the average cost and difficulty of replacing an LG range control board?

LG range control boards typically cost $150 to $400 depending on the model. Installation is moderate — usually 30 to 60 minutes. You'll disconnect the ribbon cables from the old board, remove a few screws, and install the new board. No soldering or special tools required. The hardest part is accessing the board, which is often behind the control panel. If you're not comfortable with the process, a technician can install it — but the OEM part itself is significantly cheaper at Repair Clinic than through an appliance service center.

LG Range/Stove/Oven Model Number: Where to Look

LG typically prints the model number on a label inside the oven cavity, often along the left or right wall. If you do not see it there, check the back of the range or the frame around the oven door. The label may include several numbers, so look specifically for the model number rather than the serial number. Enter that model number in the Repair Clinic search bar to narrow the full catalog to parts made for your LG range, stove, or oven. This filters every associated part category for your exact unit, not just the display or control board. You can then confirm compatibility quickly and avoid ordering a part that looks similar but does not fit.
