What should I do if my furnace light is not working?
In some cases where the pilot light won’t stay lit, the thermocouple needs to be adjusted or replaced. This is generally a job for a professional. You can clear a clogged orifice with a piece of thin wire. Before doing this, turn off the gas to the furnace. Also shut off the switch or circuit breaker that controls power to the furnace.
What causes the pilot light on a gas furnace to go out?
Continue to 6 of 9 below. On older furnaces, the standing pilot light can go out due to a strong draft, a dirty orifice in the pilot burner, or dirt in the gas tube. Or, the thermocouple may be faulty, causing the gas supply to shut off. Luckily, relighting your pilot light is fairly simple.
What does the flashing light on my furnace mean?

What does it mean when lights dim when furnace turns on?
As for the dimming of lights slight dimming is not a major thing to be concerned about but major dimming may mean it is time to tighten connections around the house if you experience the problem over two or more circuits then I’d seriously look for loose connections in a neutral somewhere.
Why is the pilot light out on my furnace?
It is important to note that constant overheating can damage your heat exchanger. When the problem reaches the heat exchanger, then it is time for a replacement. Do not wait for this to happen, replacements are more expensive than repairs. Relight the pilot light if you notice it is out.
