Examine and Clear
Usually examine the pilot meeting for any filth, particles, or corrosion. Clear the thermocouple and pilot tube utilizing a mushy brush or compressed air. This helps guarantee correct fuel move and ignition.
Test Gasoline Strain
Utilizing a manometer, measure the fuel strain on the pilot mild. It needs to be throughout the specified vary to your furnace. If the strain is just too low or excessive, regulate it accordingly to make sure optimum flame stability.
Clear Obstructions
Be sure that there are not any obstructions blocking the air consumption or exhaust vents of the furnace. Clear any particles or mud that will hinder correct air circulation and stop the pilot mild from staying lit.
Preserve Correct Airflow
Sufficient airflow is essential for a secure pilot mild. Examine and clear the blower motor and filter to make sure they’re functioning correctly and offering adequate air circulation all through the system.
Tighten Connections
Over time, connections can change into free, inflicting fuel leaks and interfering with the pilot mild. Tighten all fuel line connections, together with these on the pilot meeting, fuel valve, and thermocouple.
Substitute Thermocouple
The thermocouple generates a small electrical present that retains the fuel valve open. If the thermocouple fails, the fuel valve won’t open, and the pilot mild will exit. Substitute the thermocouple if it turns into defective.
Regulate Pilot Flame
The pilot flame needs to be a small, regular blue flame. If the flame is just too massive, it could possibly overheat the thermocouple, inflicting it to fail. If the flame is just too small, it might not generate sufficient present to maintain the fuel valve open. Regulate the pilot flame utilizing the adjustment screw on the fuel valve.
Examine Warmth Exchanger
A cracked or broken warmth exchanger can launch harmful carbon monoxide into the air. Periodically examine the warmth exchanger for any cracks or leaks, and have it repaired or changed if needed.
Use Authorized Gas
Solely use the kind of gas specified within the furnace guide. Utilizing an incompatible gas can injury the pilot meeting and result in combustion issues.

How To Gentle Pilot On Furnace
In case your furnace will not be working, one of many first issues it’s best to examine is the pilot mild. The pilot mild is a small flame that ignites the fuel in your furnace. If the pilot mild will not be lit, your furnace won’t be able to supply warmth.
To mild the pilot mild, you will have a protracted match or a lighter. First, find the pilot mild meeting. It’s often positioned on the backside of the furnace. After getting discovered the pilot mild meeting, flip the fuel valve to the "off" place. This may cease the move of fuel to the pilot mild.
Subsequent, use the lengthy match or lighter to ignite the pilot mild. Maintain the match or lighter as much as the pilot mild and switch the fuel valve to the "on" place. The pilot mild ought to ignite instantly. If it doesn’t ignite, attempt once more.
As soon as the pilot mild is lit, flip the thermostat to the specified temperature. The furnace will now begin to produce warmth.
Folks Additionally Ask
How do I do know if my furnace pilot mild is out?
In case your furnace will not be producing warmth, the pilot mild could also be out. You’ll be able to examine the pilot mild by wanting by way of the sight glass on the furnace. If the pilot mild will not be lit, it should seem darkish.
Why will not my furnace pilot mild keep lit?
There are a couple of explanation why your furnace pilot mild could not keep lit. One motive is that the thermocouple could also be defective. The thermocouple is a tool that senses the presence of the pilot mild and sends a sign to the fuel valve. If the thermocouple is defective, it won’t be able to ship a sign to the fuel valve, and the fuel valve will shut off the move of fuel to the pilot mild.
Another excuse why your furnace pilot mild could not keep lit is that the fuel strain could also be too low. If the fuel strain is just too low, the pilot mild won’t be able to remain lit. You’ll be able to examine the fuel strain through the use of a manometer.
Lastly, your furnace pilot mild could not keep lit if the venturi tube is clogged. The venturi tube is a small tube that mixes air with fuel. If the venturi tube is clogged, the pilot mild won’t be able to get sufficient air to remain lit. You’ll be able to clear the venturi tube through the use of a small brush.
