I have a Trane Gas Heater Model aud1000936h4 and there is air but no heat. On a heat command it waits about 5 seconds and then the blower turns on normally except no hot air. Nothing happens in these five second until the blower comes on. It has an auto ignition system. Unfortunately, I forgot to replace the air filter and I found it in a bad shape. I suspect this might have triggered the problem. I tried to reset it using the one-off switch as instructed in the manual but no luck. Any pointers are greatly appreciated. Ken

The blower your talking about, is that the inducer motor, if it is, you may want to check you the flue for blockage or even the hose on the pressure switch. On the wiring diagram of the furnace the may also be a diagnostic chart to see what the lights blinking on the control board is for and go from there.
