LG Oven F15 Error Code
Broil element circuit fault
What this error means
F15 indicates the broil element circuit did not draw expected current when broil was commanded—open element, bad wire, or relay not closing.
How F15 is detected
When F15 appears on a LG oven, the control board has confirmed that water did not leave the machine within the programmed drain window. On LG LRG4113ST, LG LREL6325F, and similar variants, the drain pump runs for a fixed interval—often three to seven minutes on washers and dishwashers—while a pressure switch or turbidity sensor verifies the tub or sump is empty. If water remains, the cycle stops to prevent spin with a full tub or overflow on the next fill.
Most F15 calls are resolved without parts: turn breaker off and visually inspect top broil element for gaps or blisters. Restricted drain paths mimic pump failure because the impeller spins against a blocked hose or filter. Document whether the pump hums audibly during the drain step; a humming pump with no water movement points to a clogged filter or kinked hose, while silence may indicate a failed pump motor or loose wiring at the harness.
After clearing blockages, run a short cycle and listen at the drain hose for steady water flow. If F15 returns on the next load with a clean filter and straight hose, measure resistance at the pump motor connector per the service manual for your model before ordering a replacement pump assembly.
Common causes
- Open broil element from age or thermal shock
- Burned wire at broil terminal block
- Relay not energizing broil leg
- Element connector loosened during prior service
Step-by-step fixes
- 1Turn breaker off and visually inspect top broil element for gaps or blisters
- 2Wiggle element connectors gently—they should be tight ceramic blocks
- 3Run Broil test after reset—no orange glow confirms element path fault
- 4Use Bake only until service if broil is required for recipes
When to call a technician
Element and relay tests with live voltage belong in professional service.
Affected models
- LG LRG4113ST
- LG LREL6325F
- LG LDG4315ST
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use ovens to prevent F15 from lint and food debris buildup.
- Record when F15 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 F15; LG uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting F15; reversed plugs on pumps and valves cause immediate repeat faults.
