Start with these safe checks: Make sure the gas shutoff valve behind the dryer is fully open (handle in line with the pipe) and that other gas appliances in the home work. Power the dryer off for 2 to 3 minutes, power it back on and restart the cycle. If it still won't ignite, stop and call for service. Never work on the burner, igniter or gas valve yourself, and if you smell gas, leave and call your gas utility from outside.

When should I call a technician for code HC2?

If it still won't ignite, stop and call for service. Never work on the burner, igniter or gas valve yourself, and if you smell gas, leave and call your gas utility from outside. Smell gas? Leave right away, don't touch light switches or phones inside, and call your gas utility or 911 from outside. Never open a gas valve, burner, gas line, vent or flue connection, or bypass a safety switch. Repeated lockouts, scorching, soot, or a CO alarm mean shut it off and call a licensed gas technician.
