You have a multitude of things it could be.From a open safety switch to a bad gas valve. I need to know what the model number is on the furnace. You can find that by opening the door where the burners and gas valve are and it should have a sticker in it giving model # and serial# . Once I have that I can help you. David- HVAC TECH

When I try to use my Thermolaire model SU402E, the pilot lights( and stays lit), but the main burner will NOT ignite.. any suggestions as to what could cause this if the pilot stays lit?


Bad igniter? When you 1st try it the gas valve will give enough gas that you would get the burner lit if the igniter was glowing red. If you're desperate you can light the igniter area w/ an aim n flame, but you definitely want to do that w/ caution and crank up your t-stat so the furnace stays on awhile Cuz you'll have to do it again for heat or buy an igniter($40 or so)

Janitrol GUPS075-3 Furnace burners will not stay lit


The first thing I would do is make sure the flame sensor is clean, this is a metal rod immersed in the burner flame on the opposite side of the igniter. If too much oxidation builds up on it, it will not allow the burner to stay lit. To clean, just turn off furnace and remove flame sensor and clean with steel wool and then reinstall. If this does not solve the problem there may be a problem with the gas valve.

Heater is not igniting


see this causes and fix it. God bless you
f there is no heat, check the electrical service panel for a burned fuse or tripped breaker. Relight the pilot light (see below). If there is not enough heat, adjust the burner air shutter (see below); and clean the burner ports (see below).
If the pilot light does not light or does not stay lit, clean the pilot orifice carefully with a toothpick, test the thermocouple and replace it if it is faulty (see below).
If the flame flickers, adjust the pilot (see below).
If there is an exploding sound when the burner ignites, adjust the pilot to a higher setting and clean the pilot orifice and the burner ports.
If the burner takes more than a few seconds to ignite, clean the pilot orifice and adjust the pilot light.
If the burner flame is uneven, clean the burner ports. If the burner flame is very yellow, clean the burner; open vents in the furnace room to provide more air; adjust the burner air shutter.
If the furnace makes a rumbling noise when the burners are off, clean the burner and adjust the burner air shutter.
If the air is too dry, wash or replace the evaporator pad if you have a humidifier; test the humidistat; and adjust the water-level float to raise the water level.
If some rooms are too cool and others too warm, the distribution system may require balancing. Refer to the Forced-Air Distribution Fix-It Guide .

Lennox G8Q3-90-4 will not ignite the pilot. The


While holding down the control knob for the pilot, you either have to use the pilot ignitor or match light the pilot. Then old the knob in for 60 seconds, before releasing it. If the pilot remains lit, turn the control knob to ON. If the pilot does not remain lit, the Thermocouple or Thermopile may need to be replaced.

Hope this helps you to solve the problem.

Pilot light will stay lit Lennox G8D2-82


You may need to replace the Thermocoupler. It screws into the gas regulator and the sensor end is set in the flame of the pilot light. You can get one at any appliance parts store. The Thermocoupler simply feels the heat of the pilot light and sends a very small amount of voltage to the gas switch that opens when your thermostat calls for heat. If the pilot light isnt lit, no voltage from the sensor and no gas can be released by the regulator.
Anyone can replace one. Just find the tip that sits in the the pilot flame when you try to ignite the pilot light. Follow it down to the regulator and unscrew it. There is no gas involved. It is Ultra Low Voltage. No danger.
Be sure to turn off the power to the unit before you begin removal. Take it to the parts store along with your furnace brand and model number. If you see any identifiers on the regulator, note them and take them with. When you replace it be sure to have the sensor end up in the flame of the pilot.

Can't find instructions on lennox gf 8 series furnace


Does it have a standing pilot light? On new units, there is an igniter and not a pilot. But if you have a standing pilot, you will move the gas valve to "pilot" and push down the red button while holding a flame under the pilot located by one of the jets. Once it lights continue to hold the button down for a minute or so and then release the button. The pilot should stay lit. Then turn the dial to the on position. That's it.......... If the pilot won't stay lit then the thermocouple is bad and needs to be replaced.
