People also ask, what to check if your furnace isn't working?
First, if your furnace has a pilot light, check to make sure it is lit. If this isn't the problem, and your furnace does run on gas, check your water heater. If your water heater is working properly, you can eliminate gas supply as the problem. Next, check your air filter and verify it is clean.
Furthermore, why is cold air blowing when the heat is on? 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.
Consequently, can hear your furnace click on but it does not fire up?
The Pilot Light (Faulty Ignition Sensor) The pilot light or ignition sensor is usually the most common issue when your furnace will not ignite. This is typically the problem if you can hear your furnace click on but it does not fire up. If the sensor or ignitor is dirty, it will need to be cleaned.
How do I reset my heater?
Turn the power back on and then the main gas supply. Locate the reset button. It is labeled, sometimes in red. Press and hold the reset button for 30 seconds.
