    Where can I find raley for heating unit?
    My blower is constantly working. Why? It was turning it self on and off until I changed thermostat. Now gas cuts off and on as needed to regulate temperature but my blower never stops, even when I diconect thermostat. I am under impression that it may be relay but unit is build in 1987 so I need to know where can I find parts for unit this age.
    Thanks in advance, looking forward to some good info... :confused:

    If this problem cropped up right about the time you changed the thermostat, chances are there is a connection (no pun intended). Did you follow the installation instructions? Be honest...

    Its really odd that the fan relay picked exactly the time you replaced the tstat to go bad

    If unit has a mechanical fan/limit combo, it could be sticking on the fan off switch.

    I didn't feel so bad, they were somewhat rude over the phone when I suggested they check that before I drove out there... good for their perspective on their personally assumed knowledge and worldliness, that had to be humbling...
