Do Carrier furnaces have pilot lights?

Gas furnaces now come with an igniter that works electronically to light the gas and heat the home. These newer furnaces do not use a pilot-light system as the older furnaces did. If your furnace is equipped with an electronic igniter, you cannot light the furnace manually.

Also asked, do furnaces have pilot lights?

For many years, furnaces used a small and continuously burning flame known as a pilot light to ignite the burners during every heating cycle. Although pilot lights are still present in homes with older systems, most newly installed furnaces use an electronic ignition instead.

Likewise, is it safe to leave the pilot light on? Leaving the gas on keeps this compound moving out of the tubes. Keeping the pilot light on will also keep moisture out of the unit and in turn, help prevent corrosion. As you can see, it's probably best in most cases to extinguish the pilot light in your gas fireplace during the months when you don't need heat.

Also asked, should the pilot light always be on in a gas furnace?

If you have an older gas furnace, your heating unit relies on a little blue flame known as a pilot light to ensure ignition of the burners. Water heaters, gas fireplaces and old gas stoves also often have similar pilot lights. Since the pilot light needs to remain active, your furnace is always consuming some gas.

Will gas shut off if pilot light goes out?

It should be turned off, and must be turned off to allow the pilot to be relighted, but there is a safety feature in gas appliances that if the pilot light goes out, a heat operated valve cools off and shuts the gas supply to the pilot light and the main burner.
