Why would pilot light go out?
Some of the possible serious reasons for pilot lights to go out include loose or broken gas valves, thermocouples or heat exchangers, faulty venting, low gas pressure, or high winds. If you believe there is a serious problem, don’t hesitate to contact a professional.
Why is my gas heater not igniting?

Why is my furnace not heating up?
Dirty filters are the most common cause of furnace problems. Dust and dirt restrict airflow—and if the filter gets too clogged, the heat exchanger will overheat and shut off too quickly, and your house won’t warm up. If the blower is running but no heat is coming out, replace the filter.
Why is my furnace blowing out lukewarm air?
When airflow through your vents are blocked, the burner of your furnace will shut off, while the blowers continue to run as normal. Over a short period, the fan will turn the air cold or lukewarm at best. Air filters keep the air in your home clean and easy to breathe.
Why is cold air coming out when heat is on?
