    Question

    I got a call from a friend tonight. He said he came home to a cold house and his carrier furnace baord was flashing 1 long and 3 short (or maybe 3 shorts and 1 long) He turned off the power and turned back on , and then it ignited and run normal until the stat was satisfied. He says there is nothing on or inside the cover telling what the code means. I work on Tranes everyday and dont have the Carrier fault codes in my head. Can someone tell me what to check if it does it again .
    Thanks
    Randy

    I don't have the code either, but check the pressure switch may be going or line clogged.
    also you can check the flame sensor to may have to clean it off.
    hope this helped

    i believe a 13 is an open high limit or flame roll out and a 31 is an ignition failure lockout, but i may be wrong.

    13= Limit switch lockout.
    31= High pressure switch fault.

    I dont have the model # , I do know its an 80% Carrier about 10 years old.
    Im sure it didnt "fix "itself so the problem will come back and I will have to go over there.

    Per a Google search, High limit fault: Temperatures in heat exchanger too high. High limit signaled/tripped. Air flow might be reduced/restricted such as a very dirty air filter to cause such problem.
    Found it. And yes, if Air filter is found to be ok, then a call to a qualified HVAC Tech would be in order.
