Common Symptoms & Causes

If you’re experiencing a temperature probe issue on your LG LSEL6335F electric range, look out for the following symptoms:

• The oven display shows a “Probe” error message or F3 error code
• Oven temperature readings are inaccurate or fluctuate unexpectedly during cooking
• The oven shuts off mid-cycle without completing the set cook time
• The oven fails to preheat or reaches temperature much slower than normal

These issues usually stem from a faulty or damaged oven temperature probe, which can fail due to normal wear, physical damage from heavy cookware, or corrosion from grease buildup over time.

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.

Tools & Parts Needed

Essential Tools

• Phillips #2 screwdriver
• ¼” nut driver
• Multimeter
• Work gloves (heat-rated)
• Flashlight

Replacement Parts

• Meat probe
• probe jack socket
• multimeter

Step-by-Step Repair Instructions

Step 1

Start by unplugging the range from the wall outlet — working near oven wiring with power on is a shock hazard. Once power is off, locate the probe jack socket on the oven wall and clean its contacts thoroughly with a dry cotton swab. Grease and moisture buildup on those contacts creates a false resistance reading, triggering a probe error even when no probe is connected.

Step 2

With the range still unplugged, insert the meat probe into the jack and measure its resistance across the probe’s two-pin plug using a multimeter. At room temperature (around 70°F), a healthy thermistor-type probe should read approximately 1,000 ohms; if you get a dramatically higher, lower, or completely open (OL) reading, that means the probe has failed and needs replacement. Pro tip: write down the exact reading before ordering a replacement to ensure the new probe matches.

Step 3

If the probe tests good, the fault may lie in the jack socket itself — the two-wire connector mounted inside the oven wall behind two Phillips screws. Remove the socket and use your multimeter to check continuity between each jack pin and its corresponding terminal on the control board wiring harness. An open circuit anywhere along that path indicates that the socket or its wiring has failed and must be replaced.

Step 4

A probe error that appears with no probe inserted specifically points to the jack socket failing in the open position, as the control board continuously monitors that circuit and flags an error when it detects no valid signal. This distinction tells you the probe itself is likely fine and the socket is the problem. Replacing the jack socket will restore a proper signal path to the board.

Step 5

Before restoring power, reinstall the jack socket with its two Phillips screws and reconnect the wiring harness connector until it clicks firmly into place — a loose harness connection here will bring the error right back. Plug the range back in, insert the meat probe, and set the oven to bake at 350°F. Confirm that the probe temperature displays correctly on the control panel as the oven heats; the reading should climb steadily from room temperature.

Step 6

If the error code returns even after replacing both the probe and the jack socket, the control board’s input circuit for the probe has likely failed internally. At this stage, component-level board repair is rarely practical on this model, so replacing the control board is the next step. Before ordering, make sure to record the full model and serial number from the oven door frame to ensure you get the exact board revision that matches your unit.

Where to Buy Replacement Parts

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

• LG LSEL6335F meat probe EAD64369001 replacement
• LG electric range probe jack socket replacement
• LG range probe temperature error code

When to Call a Professional

If the issue persists after following all the steps above, the problem may 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. On gas models, don’t attempt work on the gas valve, burner orifices, or supply line — that work is restricted to a licensed gas fitter in most jurisdictions.

How Much Does This Repair Cost?

Replacing a temperature probe on the LG LSEL6335F yourself typically costs between $20 and $60 for the replacement part. A professional service call for the same repair usually runs $150 to $300, including labor and parts. Tackling this repair yourself can save you $100 or more.

Frequently Asked Questions

What does a Probe error mean on my LG LSEL6335F?

A Probe error indicates that the oven’s temperature probe is either faulty, disconnected, or sending incorrect readings to the control board. You’ll need to inspect the probe and its connection before the oven can operate safely.

Can I still use my stovetop burners while the Probe error is displayed?

In most cases, the surface burners on the LG LSEL6335F remain functional even when a Probe error is active. However, the oven cavity will be disabled until the issue is resolved.

How do I reset the Probe error on my LG LSEL6335F?

To reset the Probe error, turn off the range at the circuit breaker for 30 seconds, then restore power to perform a soft reset. If the error returns, the temperature probe likely needs to be replaced.

The Meat Probe That Stops the Probe Error on Your LSEL6335F

If your range is throwing a Probe error and you’ve ruled out a damaged jack socket, the thermistor inside the meat probe itself has likely failed. Swapping in a fresh probe is usually the quickest fix—and it’ll get your range back to normal operation within minutes.

What works

• Probe connector fits the LG jack properly without forcing or wiggling—no adapter nonsense needed.
• The thermistor resistance reads clean when you test continuity, which means the range’s temperature sensing circuit recognizes it immediately and clears the error code.
• Cable insulation is intact and the probe handle doesn’t feel cheap—it actually withstands repeated insertions into the jack without cracking or loosening the connection.

What doesn’t

• This is a replacement probe, not a diagnostic tool—if the range jack itself is corroded or damaged, a new probe won’t fix the underlying problem and you’ll still get the error.
• You need to have actually tested the old probe first (or visually confirmed the jack is clean) before ordering; otherwise you might replace a good probe and waste time troubleshooting the real culprit.

In my experience, I’ve seen a few DIYers grab a probe without checking the jack connection first—turns out the socket had a bent pin and the new probe made no difference. Always inspect that jack with a flashlight before you order the part. Once you confirm it’s good, a meat probe swap takes five minutes flat.
