What d80
actually means.
d80 is LG's Flow Sense estimate that the exhaust duct is about 80 percent blocked; d75, d90 and d95 stand for roughly 75, 90 and 95 percent. On a gas LG, the same d80 can also mean the burner is short of gas.

Before you book,
in this order.
Each step comes from LG's own guidance for d80 on its dryers. Follow it to the end: the last card says whether this is a visit.
Clean the lint filter, then pull the dryer out and look for a crushed, kinked or coiled transition duct behind it.
Run the dryer and confirm from outside that air is blowing out of the exhaust hood and its flaps open fully.
If the reading returns after that, book a vent cleaning; on a gas model, also confirm the gas valve is fully open.
