It's getting cold inside! Service tech said heat exchanger failed in Oct. but heat has been kicking on when banging furnace with screwdriver

In April 2013, furnace would not blow hot air, motor was running but no air blowing. Service tech replaced thermostat. I guess it was fixed but probably did not use too much since it was Spring then Summer. In October, no hot air at times but motor running & motor getting way too hot. Service tech came & said heat exchanger failed, 320+ ppm CO in outside exhaust but none in house. We were shown how to hit furnace inside of panel & then something would engage and the gas pilots would start on fire (I look into this little window & see fire) and it would work! Now, no amount of hitting gets fire to come on. Motor runs, no heat. It is an older HEIL. TY.

I am a Heil Dealer. Your proble, could be anything from a loose wire to a bad gas valve or ignition system. First, You should never have to hit anything to get the furnance to work. This is a issue that will need to be looked at by a Technician that is qualified. I would suggest you get it checked by a another company because I am deeply concerned by what you were told that you had a unqualified tech that doesn't know much. I could help you but you would need a volt meter and Ohm meter and br able to use them. I will need the model number and serial number of the furnance so I can pull a wiring diagram on it. I will be glad to help as much as I can but it will be time consuming. Stan Stan Chaney HVAC/R Bassett, Virginia
