Your dryer isn't heating properly or is overheating
Critical

Also displayed as: HC
What This Means
Clogged lint filter restricting airflow; Restricted or clogged vent system causing heat buildup; Thermistor malfunction (resistance out of range); PCB fault
What actually causes this:
Most often caused by a clogged exhaust vent that traps hot air inside the dryer, or the heating element has burned out.
First Thing to Check
Check your exhaust vent — disconnect it from the back of the dryer and look for lint buildup inside.
