The pilot light is gone on my furnace.
For a long time, furnaces used a small and continuously burning flame known as a pilot light to ignite the burners.Most newly installed furnaces use an electronic ignition instead of pilot lights.
How do I reset my furnace?Press and hold the button in the center of the component.The button should be held for one to two seconds.
The knob should be turned to "Pilot" once the gas has dissipated.Bring the flame of a long lighter close to the pilot light opening if you hold down the "Reset" button.This will light the furnace pilot light.Release your pressure on the reset button if the pilot light is on.
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 main burner.When the flame goes out, the pilot light goes off.
The pilot light is the most common issue when your furnace won't start.If you can hear your furnace click on, it's usually the problem.The ignitor will need to be cleaned if it is dirty.
The most common cause of furnace problems is dirty filters.If the heat exchanger is overheated and shuts off too quickly, your house won't warm up.If there is no heat coming out of the blower, it's time to replace it.
In the summer, you should turn off your furnace.Let me tell you more.If your furnace is left on, it will consume energy all summer.Gas will be burned around the clock by the pilot light on gas furnaces.
The power to the furnace should be turned off at the circuit breaker.The circuit breaker is marked.The blower wheel and blower motor can be accessed by lifting up the blower compartment cover.There is a small red or yellow button on the side of the blower motor.If it pops up, press the reset button.
If your furnace has a pilot light, make sure it's lit.If this isn't the problem, you should check your water heater.Gas supply can be eliminated if your water heater is working well.Check your air filter to make sure it's clean.
The limit switch is usually located above the heat exchanger of the furnace in the hot-air supply plenum.
When there is a call for heat in a furnace, an open limit switch will always bring on the main blower as a safety feature, but it is not the blower control which operates on a timer.From heat and constant cycling, the limit switch can go bad.
Find your furnace's heating duct to reset a furnace limit switch.There is a white limit switch.You can identify the settings by looking at each arm.The setting is located between the two arms.The temperature on the middle component should be 105 to 115 degrees.
The furnace may be blowing cold air because the filter is dirty.A dirty air filter blocks the flow of air into the furnace.The heat exchanger can crack if your furnace trips a high limit switch.
Can a pilot light be dangerous?When a pilot goes out, the gas valve that supplies the fuel for the pilot flame could still be malfunctioning.A very serious explosion is possible when the pilot is relit or relights itself.
The most common cause of a boiler failing to provide heat is a burner that won't ignite.The water in the tank will not warm up if the gas jets on the burner don't ignite.A failed electronic igniter/pilot light may be the reason for the trouble.
The small metal tube below the burner assembly is the pilot gas line.If the pilot is lit, there will be a small blue flame at the end.The pilot light is out if you don't see a small blue flame burning.
