Why does the flame keep going out on my furnace?

Why does the flame keep going out on my furnace?

If you are trying to light a standing pilot light on an old furnace but it keeps going out, make sure you are holding the pilot button long enough. This gives the flame enough time to heat the flame sensor (thermocouple) that tells your furnace it’s OK to light the burner.

Why does my furnace keep shutting off after a few seconds?

If your furnace shuts off too often, you could have a corroded or dirty flame sensor. If the flame sensor is dirty or has become corroded, the flame won’t register and will turn off the gas valve, which, in turn, causes your system to shut down.

How do you know if a flame sensor is bad?

How do I know if my furnace flame sensor is bad?

  1. Switch off the power to your furnace.
  2. Close the gas valve.
  3. Take out the mounting screw.
  4. Carefully pull out the sensor.
  5. Inspect the sensor: if the insulation is intact but appears sooty, burnt or slightly corroded, it might only require cleaning.

Why does my furnace blower keeps turning on and off?

If your blower is constantly turning on/off when the furnace isn’t heating… …you most likely have a bad fan limit switch. So if your furnace blower is turning on and off when the furnace isn’t in a heat cycle, it usually means the fan limit switch is defective.

Why does my heat not stay on?

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.
