    Trane furnace troubleshoot heating control
    TRANE MODEL: TUY060R9V3V3 SERIAL: Z313Y8F7G about 6years old.
    Thermstat calling for heat. Furnace does not purge or heating come on. Red LED is blinking about 1 time per second. Green LED blinks much more slowly. Yellow LED's at G, Y, & YLO, do not light up.
    5 amp fuse appears to be good.
    I put new batteries in the thermostat, no change.
    This is gas heat with an electric Air conditioner, not heat pump.
    Tempered R & BK, no change.
    Control is C341033P01 and labell inside furnace door panel say replace with CNT2536.? Don't understand why!
    I powered down outside breaker to AC, and inside power switch , no change except I could hear relay drop out upon each "power off /power down".

    Look on the back side of the blower motor access door for the blink/flash code legend

    Looks like a normal heating call and that would be good. However, the furnace does nothing else.
    Please list next couple of troubleshooting items.
    I guess ignighter or other safeties
    Can you help more.
    Thanks very much.

    That unit has a variabble speed draft inducer along with a 2 stage gas valve. This unit is not used friendly to service since many of the parts have to be replaced since the original trouble prone items are NO LONGER available. I suggest you have on site service for your unit.

    You can jump the thermostat out to eliminate it from the circuit for testing purposes .
