The furnace pilot light may not light up due to issues with the gas supply, a faulty thermocouple, a dirty pilot light, or a malfunctioning ignition system. It is important to troubleshoot and address these potential issues to get the pilot light to light up and the furnace to function properly.
There are 55,000 BTU in an intertherm furnace pilot light. It is a way of heating up a place.
This question is not specific enough for a good answer. What is the appliance? A furnace? A cooktop burner? An oven? The first thing to check would be the igniter, which is what typically "lights" the gas coming from the valve. You can check an igniter with a simple continuity test using a test meter. If the pilot is lit, then there is no igniter, or the igniter lites the pilot, so if the pilot is lit how could it be the igniter. Bad thermocouple, this tells the gas valve that the pilot light is lit, if the gas valve does not know the pilot is lit it will not allow gas to come out of the valve, this is a safety feature so your unit does not blow up.
Could be lots of things. If you have a standing pilot light, one that stays on all the time, the thermocouple may be bad. A thermocouple is a small rod that sits in the flame of the pilot light. It then runs to the gas valve. This produces a small amount of electricity that keeps the valve open to let the gas in. If the pilot light goes out it shuts the valve so the house doesn't blow up. Easy enough to replace. If the pilot light is still on and the furnace will not light, it has to be the thermocouple. Check fuses at the furnace and in the panel. Newer gas furnaces have a circuit board in them that can go bad. There are a dozen things that could keep it from working, it is just a process of elination.
Here are some things to check. Is the thermostat turned up? Sounds silly but I went into many homes it was turned down, or the switch on the thermostat was turned to off Is the pilot lit? This assumes you have a standing pilot furnace. If it is spark ignition, does the park cycle start. Check all fuses and breakers
Well I don't know if this works all the time but I tapped on the Combination control ( the thing that the main gas line comes in to with the switch for the pilot light is on) that thing and my furnace lit up. Like I said don't know why or how it worked but it did! Good luck
Remove the pilot assembly from the furnace and clean it up. You need to be careful when putting it back on at the gas valve so as not to crossthread the screw. Take a thin wire and clean the pilot orifice, then use a brush or sandpaper on the thermocouple.
1- Defective gas controller2- Thermostat/ aqua stat not calling for heat3- electric shut offTripped or defective safety device, gas valve set on pilot, bad transformer. Don`t kill yourself looking for the aquastat. That is a boiler control and your furnace does not have one.Electic good-- whatelse can I test?
the pilot light in my fireplace is working but when i turn the switch on (new switch) it wouldn't fire up
i have a 20 year old rheem gas furnace with an electric ignition. when i turn up the thermostate, the pilot starts up but that's it. it doesn't do anything else. What could be the reason for this?
The furnace ignitor may light up but not produce a flame due to issues such as a clogged burner, a faulty gas valve, or a lack of fuel supply. It is important to have a professional inspect and repair the furnace to ensure safe and efficient operation.
My wall furnace has an overheat safety switch. It's up near the top on the side of the unit. If the exhaust vent gets too hot, it will trip the switch off. I use a small screwdriver to reset the switch by pushing the little red button. The switch when activated shuts the thermostat to off. By resetting it, the thermostat will now work.
To light a pilot light on a wall heater, locate the pilot valve and turn it to the "pilot" position. Hold down the control knob and use a long lighter to ignite the pilot flame. Keep holding the knob for about 30 seconds to allow the thermocouple to heat up. Release the knob and the pilot light should stay lit.
