Heat after drying can be expected; an unusual increase accompanied by odor, smoke, or protective shutoffs means use must be stopped. Do not check the temperature by touching areas that may burn you.
Normal cooling and signs of failure
If the cycle runs without issues, let it complete its cooling phase and follow the unloading instructions. Avoid interrupting it out of habit and leaving hot laundry piled up.
The LG F4X7*FPY* safety manual warns about heat dissipation if drying is interrupted. If you see smoke or suspect a fire, do not risk retrieving the load: follow the procedure for burning or smoke and contact emergency services.
What can affect the temperature
Air circulation restricted by lint, a fan that is not doing its job, or incorrect thermal regulation can change the behavior. These are possibilities to check according to the system, not diagnoses inferred from the heat of the cabinet.
With the unit stopped, cool, and unplugged, inspect only the filters and accessible areas documented by the manufacturer. Do not open internal ducts or insert objects toward the fan.
If there were shutoffs or it heats up abnormally again
Request an inspection of the drying circuit. Do not bypass thermostats or reset limiters without correcting the cause. If the problem affects water during washing, see excessive water heating.
Letting the unit cool down does not confirm that circulation or regulation are working correctly again; avoid another drying cycle until the fault is identified.
