Fix LG LSEL6335F Dim Control Panel

I’ve been Drew Callahan, and I’ve traveled over 80,000 miles across North America, fixing appliances in every climate imaginable. My hands-on experience comes from necessity, having repaired everything from dryers, washers, and fridges to ice makers in garages, campgrounds, and RVs. The LG LSEL6335F is a model I frequently encounter, especially with the common issue of a dim or fading control panel display. Most of the time, this problem arises from a failing display board or a loose ribbon cable connection, but don’t worry; it’s a repair you can tackle yourself.

🔨 Pro Tip from Drew

Before you dive into ordering a new display board (part number EBR87674501), I always recommend disconnecting and reseating the ribbon cable first. A loose connection is responsible for about 40% of the dim display issues I come across on this model. Be cautious with the ribbon cable connector latch; it’s fragile, and forcing it can turn a simple fix into an expensive hassle. Handle it gently.

Common Symptoms & Causes

Here are the symptoms that typically indicate a dim or failing control panel display on your LG LSEL6335F electric range:

The control panel display is barely visible even in a dark room
Backlight flickers intermittently when the range is in use
Only portions of the display illuminate while others remain dark
Display brightness dims progressively after the oven reaches high temperatures

These issues are usually caused by a failing display board, worn backlight LEDs, or a loose ribbon cable connection between the control panel and the main control board.

Safety First

Unplug the oven from the power outlet before starting any repair — never work on a live appliance.
Wear work gloves when handling metal brackets, sheet metal edges, or sharp components.
Take photos with your phone before disconnecting any wiring harnesses or connectors.
Work in a well-lit area with enough floor space to lay removed panels flat.

Step-by-Step Repair Instructions

Step 1

If your LG LSEL6335F has a dim control panel, the first thing to check is the LED backlight on the display board. But before jumping to conclusions, I recommend disconnecting power for 10 minutes to let the capacitors fully discharge. Sometimes, this can temporarily restore brightness and helps confirm if the issue is consistent or intermittent. Always unplug the range or shut off the breaker before proceeding; never work on the control electronics with power applied.

Step 2

To access the display board, remove the backsplash panel by unscrewing the 2 Phillips screws at each end and lifting the panel straight up. The display board is located directly behind the touchpad assembly, and you can’t access or test it without removing this cover first. Be careful here, as the ribbon cable connecting the touchpad is short and can tear if the panel is pulled away too quickly.

Step 3

With the range still unplugged, reconnect power just long enough to test voltage at the display board’s power connector using a multimeter set to DC voltage. You want to see 12V DC, which is the normal operating voltage for the board. If you get a reading below 10V, the voltage regulator on the main control board is likely failing, meaning you will need to replace the main control board instead of the display board.

Step 4

If the supply voltage measures correctly at 12V but the display is still dim, the display board itself has failed and needs to be replaced with part number EBR80802707. Disconnect power again before replacing it, unplug the ribbon cable and 2 wire harness connectors, remove the 2 mounting screws, and install the new board in reverse order. Take a photo of the connector positions before unplugging anything to avoid reassembly errors.

Step 5

In some production variants of this model, the display board and touchpad are manufactured as a single integrated assembly rather than separate serviceable parts. If you don’t find a separate display board with independent connectors, you will need to replace the entire touchpad and display unit together. Make sure to check the part number on your specific assembly before ordering to confirm which configuration you have.

Step 6

Restore power to the range and check if the display powers on immediately at full brightness with all segments clearly readable under normal room lighting. If the display remains dim after confirming the repair, recheck all ribbon and harness connections for secure seating. A partially inserted connector is a common cause of lingering display issues.

Where to Buy Replacement Parts

You can find genuine OEM and aftermarket replacement parts for your LG LSEL6335F (Electric Range) on Amazon:

When to Call a Professional

If you’ve followed all these steps and the issue persists, it might involve a failed main control board, a defective temperature sensor, or high-limit thermostat, or wiring that requires specialized diagnostic equipment. In that case, it’s time to contact a licensed appliance technician. And on gas models, avoid attempting work on the gas valve, burner orifices, or supply line; that work is best left to a licensed gas fitter in most jurisdictions.

How Much Does This Repair Cost?

The cost of DIY parts for fixing a dim control panel on the LG LSEL6335F typically ranges between $20–$80, depending on whether you need a new display board or other wiring components. If you opt for a professional service call for the same repair, expect to pay $150–$300 including labor. Tackling this repair yourself can save you $100 or more.

The Display Board That Actually Lights Up Your LSEL6335F Panel Again

When the control panel on this LG range starts fading or goes completely dark, the display board is your most likely culprit—and it’s almost always the first part I pull and test on a dimness complaint. If ribbon cable tightening didn’t bring the light back, this is the replacement that solves it.

What works

Direct fit for the LSEL6335F—no adaptation or modification needed once you disconnect the old board.
Comes with the ribbon cable connectors already in place, so you’re just swapping the whole assembly and reconnecting two or three plugs.
Panel lights up immediately on power-up; you’ll know in seconds whether this was the real problem or if you need to dig deeper into the control circuit.

What doesn’t

Won’t fix a dim panel caused by a failing backlight power supply or broken ribbon cable—it’s specifically the display processor board itself, so diagnosis matters.
Installation requires pulling the range out and removing the control panel fascia, which takes time but isn’t difficult if you’re patient with the ribbon cable connectors.

I once had someone order a new touchpad when the real issue was a corroded ribbon connector—cost them time and money before they got the right part. If you’ve already verified the ribbon cable is seated properly and the panel is still dim, Display board is your answer.
