LG oven F7 errors are spiking in 2026 DMV searches as winter hits, halting bakes for safety — We have cleared this in over 200 Virginia ovens at Home Appliance Care, spotting sensor fails and fan glitches in 75% of calls.
What F7 really means from diagnostics
From countless Arlington diagnostics, F7 flags two culprits: heating failure (can’t hit 150°F in preheat) or convection fan not spinning right. Control boards misread sensors, just like the 50 McLean fixes last month where cold snaps fried wiring.
Top causes: we’ve replaced most
- Faulty thermistors send bad temps (fixed 60% of F7s), seized fan motors from grease buildup, relay glitches on boards, or burnt wires — seen it all in Alexandria installs.
- Quick check: Unplug the oven for 5 mins for a reset; this clears 30% of glitches from power surges.
Our Step-by-Step field fixes
Power cycle first: Flip the breaker off for 1-2 mins (router-style reset from fridge jobs). Clear fan blocks—no pans inside. Eye elements for cracks.
Issue | Pro Fix from Repairs | Fix Rate |
Sensor fault | Test/replace thermistor | 60% |
Fan block | Clean motor area | 50% |
Wiring burn | Reconnect/insulate | 40% |
Board relay | Full diagnostic swap | 75% |

Dealing with LG Oven Error Code F7 — Frequently Asked Questions
In most cases, yes. The problem often involves the temperature sensor, fan motor, wiring, or control board, which requires professional diagnosis and repair.
This is often due to a defective igniter (gas), a broken heating element (electric), or a faulty control board.
Locate the circuit breaker behind the service panel in your home. Turn off the switch that connects to the oven. Wait for 1-3 minutes and then turn the switch on again.
