How do I light pilot light on furnace
Check that you are getting voltage from the thermocouple. You should see about 600 millivolts.
I was told by Teledyne Laars that your pilot generator needs to produce at least 500mv to open the gas valve. Mine makes 350mv and will not open the valve. Hmm, I think that should be nearer to 600 mv - 700 mv.
Have you rotated the gas valve knob to "run". Have you turned up the thermostat? Is the pump running? No pump water flow - no heat -- no filtration. Is the filter clean? When was the last time you cleaned the filter? Ken
sit on it then throw it into a creepy cave
It could be it. The pilot generator may be weak. The Valve could be defective. The High limit or other safties could also be defective. Could be corrosion on the connection. could be a water flow broblem. could be a weak flame
At pilot light, pilot light flows around thermocouple.
No standing pilot, it is a spark ignition unit
From what I have read, 500mV is not enough to keep the pilot light lit. Here is what I read on a different site: "You can check if this is the problem by measuring the voltage on the wires coming back from the pilot. When you have the red switch depressed, check the voltage (should be about 200mV). If there's no voltage, then change the thermocouple. The thermocouple will generate up to 750mV in a pilot flame. If it falls below 550mV it should kill the fuel source." Hope this helps.
Defective thermocouple or possibly a dirty or clogged pilot orifice.
If this is happening you need to get your furnace serviced by a qualified engineer.
There are 55,000 BTU in an intertherm furnace pilot light. It is a way of heating up a place.
