Question about Heating & Cooling
You can temporarily cut off the power, expose control board, pry off upper rear relay plastic cove, remove spring and stretch it out just a little from its original length because the relay is either getting weak or there are other problems with the board supplying the proper voltage to it... anyway, when putting the spring back on be sure the relay switch is properly aligned in the holes furthest away from the board.. This should provide at least several more months of proper operation before board needs to be replaced... Quick fix, install new board... Tech Chris w/ Absolutely Fabulous! AFSO.US
