Why is my furnace making a clicking noise and giving heat?
Most likely, your furnace is making a clicking noise and not providing heat because your furnace’s spark igniter is trying to ignite your pilot light or burners but is failing to do so. In other words, there’s an ignition system malfunction that needs to be fixed.
Why is my pilot light not working on my furnace?
Pilot light problems are sometimes related to failed safety sensors or airflow issues which causes the furnace blower will come on but not to ignite. The two place to check first are the thermocouple and the sail switch. A sail switch is essentially an on/off switch, that detects if there’s not enough airflow.

What do you do when your gas furnace won’t light?
When the temperature get down to the specified low, the gas valve opens and LP or liquid propane flows through an orifice to the burner assembly.

Why does the ignitor on my gas stove keep clicking?
The ignitor will keep clicking as it tries to spark a flame. This could indicate a dangerous gas leak or clogged gas valve. Irregular clicking sounds coming from the gas valve could also be a sign of insufficient voltage. This might be caused by faulty gas meter controls or the thermostat controls.
How can I tell if my furnace Ignitor is faulty?
If you have a faulty furnace ignitor, it won’t produce that small spark to heat the air coming from your furnace. Without it, your heater blows air at the same temperature as the cold outside air. Cold air blowing through your vents is a good sign that you have a heating problem within the furnace.
Why is my gas furnace making a clicking noise?
If the flame sensor is malfunctioning then it will not detect the spark igniter so it will not open the valves and let the gas through. Pilot light/flame issues: The pilot flame may not be hitting that flame sensor due to an incorrect mixture of gas and air. This can result in the “clicking” noise. Gas valve isn’t energized:

Why does my heat exchanger make a clicking sound?
Heat exchangers are made out of metal. Over the years the constant heating and cooling off of your heat exchanger can cause cracks in the metal. The clicking sound you hear could be the metal in heat exchanger heating up the cracks and they start to expand a tiny bit.

Why does my furnace make a clicking noise?
Reasons a furnace might make a clicking noise includes: Loose inducer: Oil-powered furnaces use a motor-powered fan, or inducer, to push out smoke and fumes. Worn motor bearings: The bearings in the furnace’s motor will click when they become worn.
Why is my furnace clicking?
