I try to light my pilot light and it won't take....it lights up, but when I disengage the control it burns out before I can change settings.....I have had it lit in the past, but this year it is being stubborn.....and I understand that you have to allow for it to prime first for about 1 to 2 minutes....

Re: pilot light won't take
If it goes out after being lit for 30 seconds, you need a new thermocouple. That's the tubelike piece that the flame touches. You can possibly just put in a universal thermocouple. They cost less than $5 at most hardware stores.

It's a burner control problem. It maybe a defect on some protective devices (pressure switch, fire detector, etc.), a blown fuse, or a board defect (busted DC supply transformer, relays, or electronic devices).
Is this an older furnace where you have a pilot light? Are you saying the pilot light will not stay lit? If thats the case then likely you need a new thermal couple. That is what the pilot light keeps hot while it stays lit. It is a safety device that is there so your furnace will not come on if there is no pilot light present. Very common. Hardware store item. Need Furnace's make and model #'s. If this is an electronically controlled furnace, you will need a service call.
The pilot flame must touch (burn) the tip
oqef the t-couple to hold the magnet in the gas value open.make sure the pilot orifice (hole) is clear.the pilot pressure (in the tube) is factory set full open & can only be adjusted down (less). Also check the gas **** didn't get closed or turned half way.? Assuming its not the t-couple. If all is good & it still won't stay on. Replace the gas value.!
Either the thermocouple connection into the gas control valve is loose or the thermocouple needs replacing. Also check the burner and pilot assembly inside the screen area for dust, dirt and insect build up. A clogged pilot can mimic a faulty thermocouple.
Hope this helps you in troubleshooting and solving the problem.
Turn the control valve to the PILOT position and push down and hold it in. Press the Ignitor Button and continue to hold the Control knob down, once the pilot lights. Wait one minute, release the Control Knob and if the pilot remains burning, turn the Control Knob counterclockwise to the ON Position. If after the burners light and burn for a few minutes, you can turn the Control Knob back (Clockwise) to the Pilot position (if you don't want the heater to come on automatically) and the pilot should remain lit.
you can only test this with a volt meter capable of testing milivolts. or replace the thermocouple. the thermocouple is what the pilot flame is burning onto. the pilot flame could also be weak due to a dirty pilot orifice in which case the flame will appear lazy and yellow /orange. the thermocouple should test 30mv + - 10% you should contact a service company if replacing the thermocouple doesnt fix because gas isnt somthing a un-qualified DIYer should risk there home with.
