LG Oven Error Code F19: How to Fix It

The Logic Verdict

Sarah from The Savvy Professor demonstrates that F19 isn’t a mysterious lock fault—it trips because the oven never reaches the 150°F checkpoint. Her workflow starts with a hard reset, then she shows how to lift the door off its hinges, drop the bottom panel, and expose the bake assembly. From there she replaces the MEE61841401 glow igniter (common on LG gas ranges) and, if the flame still never lights, she moves to the upper-left corner of the cavity to swap the 6322B62214A temperature probe. Once either failing part is replaced, the oven preheats normally and the code clears on its own.

What It Means

F19 = oven failed to heat to its minimum preheat temperature. The main board times how long it takes to hit ~150°F. If the bake flame never lights or the sensor never reports the rise, the board assumes a heating failure, stops the cycle, and flashes F19.

Common Causes

• Weak or open bake igniter. A glow bar that only draws two amps won’t open the gas valve, so the flame never lights.
• Failed temperature sensor. A shorted or open 1080 Ω probe feeds bogus data to the board and convinces it the oven is cold forever.
• Loose modular connector. The quick-connect behind the rear liner can back out when the door is removed, breaking either the igniter or sensor circuit.
• Latched control board. After a power surge the relay logic may freeze, so the oven benefits from a full power reset.

Step-by-Step Fix

1. Kill power for a reset. Turn the breaker off or unplug the range for five minutes to clear any latched relay faults, then restore power and test. If F19 returns immediately, continue.
2. Remove the door and floor panel. Open the door halfway, flip the hinge latches up, lift the door off, and set it aside. Pull the racks, remove the Phillips screws holding the bottom panel, and lift the panel plus flame spreader out so the igniter is exposed.
3. Swap the bake igniter. Unthread the 1/4” hex screws that hold the MEE61841401 igniter to the burner tube, pull the wires toward the front, disconnect the plug, and install the new igniter without touching the glowing element. Route the wires back through the channel so they don’t get pinched and reinstall the flame spreader and bottom panel.
4. Replace the temperature sensor if heat still stalls. Remove the single screw in the upper-left rear wall, ease the 6322B62214A probe forward, disconnect the modular plug, and clip in the new sensor. Feed the slack wire back through the hole so the insulation sits flush and reinstall the screw.
5. Reassemble and test. Slide the racks back in, set the door back on the hinges, drop the locks, and start a 350°F bake cycle. The flame should light within 60 seconds; once the thermostat reports a real temperature rise, F19 clears automatically.

Parts & Tools

• LG MEE61841401 oven igniter (restores proper amp draw so the gas valve opens)
• LG 6322B62214A oven temperature sensor (corrects bogus temperature feedback)
