I have a carrier crusader model number 58ssc075-gc. I am getting no heat, when I self test by touching a penny to the 2 self-test posts, the small black fan at the top of the unit comes on, the ignitor becomes hot, I hear what I believe is the click calling for gas, then nothing. When I call for heat with the thermostat, the big fan comes on for about 15 seconds and then nothing. I am not sure what to do next. Any ideas will be helpful as I am a single mom with 4 kids and we are freezing. Thanks in advance

Turn off power to furnace and try it again. Is there any way air could have got into the gas line? If so you may need to try to light it several times. It sounds like the igniter is trying to light the gas but either no gas is flowing or the part that proves the flame has failed. Another possibility is that the switch is bad that proves combustion air, but I doubt it since it is trying to light the burner. Those furnaces have an electronic control board that controls everything, but they rarely fail. Give me the model number and I will see what I can find on the furnace. DrTom4444

Thanks so much for your help. It is a carrier crusader model number 58ssc075-gc. I have tried lighting it many times, and I have never smelled any gas at all. I hope that helps.
Thanks again

For some reason you are getting no gas. Has the gas company turned off your gas? You need someone to check to see if you have gas at the gas valve. It requires one to turn off the valve and loosen the fitting at the valve then turn on valve for a second or two to see if you have pressure. They will need a couple of adjustable wrenches. You seriously need to take some courses at the local trade school so you will know how to fix these routine things around the house. I would suggest an HVAC course. There is no reason why you could not do this. What state are you in? By the way, you will need a meter and learn how to use it because almost all problems are electrical. If you know how to use a meter you can fix anything. Everyone needs this knowledge unless married to an engineer. It's very easy to learn and you can learn it in an hour or so. DrTom4444
