    How old is the furnace? Is the gas turned on going to the unit is the pilot lit if it's a standing pilot system? Give us as much info as you can and I bet one of us can help.

    One of the first things to check is if you have 24 volts to the thermostat. Then make sure it is getting to the gas valve, between the gas line and your cylinders. To do simple checks like this you do need some tools. A test light, a meter, or a voltage detector might be the best place to start with. I came across the niftiest gadget for trouble shooting, a voltage detector. They work through the insulation of wires. There are several brands. I have a GB Instruments GVD-505A, less than $15 at Home Depot. Touch it to a hot wire, and the end glows red. Find the doodad that lights it on one side, and not the other, and you have the culprit. You do not have to open up housings and expose electrical contacts. You are looking at where your hand is, not where the meter is. Most people are capable of doing repairs and will get it going and not get hurt if they use a little sense. The voltage detector makes it even easier.
