LG Oven F14 Error Code
Meat probe circuit fault
What this error means
F14 reports a fault on the meat probe jack—short, open, or invalid reading while probe mode is selected or the jack is contaminated.
How F14 is detected
LG oven models lock the door or lid before energizing fill, heat, or high-speed spin. F14 means the latch switch never sent a "locked" signal to the main control, or the lock motor did not complete its travel. On LG LRG4115ST, LG LREL6325F, and similar variants, clothing caught in the gasket, a misaligned strike, or a failed latch assembly are the most common mechanical causes—not the board itself.
Inspect the door gasket perimeter and strike alignment before replacing the latch. Probe not fully seated in the jack is reported frequently on this code. After correcting mechanical issues, remove the probe completely and cancel probe mode. If the latch clicks but F14 persists, the door lock switch or wiring harness to the control board likely needs testing with a multimeter.
Do not force the door open during an active cycle; wait for the lock to release when the board de-energizes the lock motor—usually two to three minutes after canceling power on most LG units.
Common causes
- Probe not fully seated in the jack
- Damaged probe cable with broken conductors
- Greasy jack shorting contacts
- Board probe input failed
Step-by-step fixes
- 1Remove the probe completely and cancel probe mode
- 2Clean the jack with dry cotton swab—no liquid cleaners
- 3Test with a known-good LG probe if available
- 4Use standard Bake without probe to confirm oven heats
When to call a technician
F14 with no probe inserted indicates jack or board repair.
Affected models
- LG LRG4115ST
- LG LREL6325F
- LG LDG4315ST
Prevention & maintenance
- Wipe the door gasket weekly and avoid overloading items against the seal—F14 often starts as a slow leak or latch misalignment.
- Record when F14 appears in the cycle and whether it clears after a 60-second power reset on your LG oven—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for F14; LG uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting F14; reversed plugs on pumps and valves cause immediate repeat faults.
