Question by : My furnace wont kick on when i turn up the thermostat but the pilot light IS lit, Please help, single mom?
I checked the pilot light and its lit, flame is strong like its supposed to be. When I turn the thermostat there is no click, If anyone can help with any suggestions I would really appreciate it, I cannot afford to call a heating company to fix for .

Of coarse the gas valve knob should be in the on position if you have recently lit the pilot. If that is ok and you do have power to the furnace the thermostat should engage the gas valve. If not there may be a safety or limit switch open not allowing control voltage to the gas valve. Many limits are resetable with a button located in the middle of the switch. Usually located around the burner and near the main blower. Limits trip for a reason so be aware there may be another problem.Without more info about what you have we are guessing so the more info the better. There are many types of furnaces and brands but I guess we do know you have an older model that has a pilot.
