LG dryers with sensor drying.
Before you book,
in this order.
Each step comes from LG's own guidance for HS on its dryers. Follow it to the end: the last card says whether this is a visit.
Wipe the sensor strips inside the drum, below the lint filter, with a damp cloth or paper towel.
Let them dry completely before the next cycle.
Book a visit if HS appears again.
What not to do
A long cycle with HS showing does not mean the heater has failed; the dryer simply cannot tell when to stop.

LG dryer repair
Electric dryer
The most common dryer in US homes: a 240-volt heating coil, a belt-driven drum and a vent to the outside.
Gas dryer
Heat from a burner on natural gas or propane, lit by an igniter and watched over by a flame sensor, with the motor on 120 volts.
Stackable dryer
The dryer half of a stacked pair or a single-frame laundry center, where the height and the closet decide how the repair is done.
In LG's own words
The HS code will cause the dryer to run for two and a half hours which may seem as though the dryer is not drying.
