Try jumping out the thermostat (red and white wires) that run to the thermostat these tell the heater to come on. Jump them together if you have heat it is the thermostat, if no heat it is the furnace. Should it be the furnace I would first check the thermocouple or some manufacturers call it a flame generator. Clean this with steel wool and position it in the top center area of the flame as this is the hottest part of the flame. Good luck
If it touched a grounded metal surface, it is possible, leave the wires hooked up at the furnace, pull the thermostat off of the wall, disconnect the 2 thermostat wires, and then twist them together, the furnace should fire, if it does, then the thermostat is shot. Replace the thermostat, usually when there is a short, it burns out the heat anticipator on the thermostat.
Jump the two wires going to the thermostat, if it starts , you have either a bad thermostat or a broken thermostat wire. If it does not fire up, you will need to check for 24 volts AC going to the gas valve from the transformer. If you have voltage, you have a gas valve issue. If no voltage, check for a limit switch that may have overheated with an Ohm meter. If they all test good, replace the transformer.
Take the two wires going to the thermostat and cross them. If the unit starts, you have a bad thermostat. If it doesn't, at the heater put a jump wire across the terminals where the thermostat wires are connected to. If the unit starts, one of the wires going to the thermostat are broke. If it still doesn't start you may have a bad transformer. Check for 24 volts AC across the two terminals on the gas valve. If yes, bad gas valve. If no, bad transformer.
can you manually fire the unit w/o the thermostat by shorting 2 of the 3 wires, there may be more wires than that, but you should be able to fire it on 2 to 3 wires alone let me know it sounds like something is floating voltage wise on the unit
