Why is my gas furnace blowing cold air?
Your furnace may be blowing cold air because the filter is too dirty. A dirty air filter blocks airflow over the furnace’s heat exchanger, causing it to overheat. When overheating, your furnace can trip a high limit switch, causing the furnace burners to shut off so that the heat exchanger does not crack.
What happens when the pilot light goes out on a gas heater?
Gas heaters, whether they warm up air or water in a home, rely on a pilot light to trigger the flame of the actual heater. If this pilot light ever goes out, the heater has no way of actually turning on to heat the water or air that your particular type of heater circulates to warm the house or other elements.
What to do when pilot light on heat and Glo does not stay on?
If the pilot light in the Heat & Glo will not stay on, there are some steps you can take to troubleshoot the problem, so you can then correct the issue and keep the pilot light lit. Verify the pilot flame is touching the thermocouple. The pilot light is flanked on both sides by a piece of the lighting system.
What to do if the pilot flame is not reaching the thermocouple?
If the pilot flame is not reaching the thermocouple, then adjust the pilot flame up so that it reaches the thermocouple. Identify that the connection between the thermocouple and the gas valve is tight and the tube is fully inserted into the thermocouple.
How often should I Check my gas heater pilot light?
A toothbrush works well, but you can also run a piece of flexible wire in and out of the orifices on the tip to scrape debris off. You should check at least every six months for the best results, although your manufacturer may have a different suggestion.

What to do if your pilot light wont work?
First, locate the thermocouple to clean it using a piece of sandpaper. Always remember to shut off the gas before you start cleaning and to make sure that your thermocouple is cool. If you’re thermocouple still doesn’t work after cleaning, the issue may be that it’s bent.
Can a thermocouple be bent away from the pilot light?
When it’s bent to a certain extent away from the pilot light, it’s no longer functional because it won’t be able to detect the heat. To fix this is also simple: bend the thermocouple back into its original position. Make sure to bend the thermocouple back so it’s close enough to the pilot flame so it lightly touches the thermocouple.
