LG's LREL6325 Self Clean offers three cycle lengths: press Self Clean once for four hours (moderate soil), twice for five hours (heavy) and three times for three hours (light), then START. Take out the racks, broiler pan, grid and any foil first, open a window or run the hood fan, wipe up heavy spills and make sure the oven light cover is in place. It will not start if the controls are locked, or if the oven is too hot, and you cannot open the door until it cools. An F code and three long beeps mean the cycle malfunctioned.

Wait for the lock
ReversibleThe oven door locks automatically about 15 seconds after start and the lock icon stays lit; do not force it.
Expect normal signs
ReversibleLG says crackling metal, white ash, a running fan, an oven light that cannot be turned on and cooktop elements that cannot be used are normal during the cycle.
Finish up
ReversibleWhen the oven has cooled and the icon is off, wipe ash with a damp cloth; repeat the cycle if the oven is still dirty.
Model-specific
What is true of this model and not of its siblings
- Foil rules
- Never line the oven bottom or walls with foil, which melts and can ruin the finish. Wrap food in foil, or put foil on a sheet pan on a lower rack, but keep it off the heating elements and away from the racks' air flow.
