Trane model YCC024F1L0BC Mfg 05/96 "Forced Air Furnace with
Cooling".... a.k.a "Packaged Gas Electric Unit"... Board inside unit
info = C662900G01 and CNT 1634 and Model 1068-100. Noted a red LED
light blinking, once per second. No place to read out any error codes.
Unit sat unused for several months while house was empty. Cooled OK
summer. Now cycling Heat to Off (wait 10 sec) then to Heat to get heat
to restart after temp falls
below setting. Replaced theromostat, no change. Would like to fix
or know how much I am looking at paying, i.e. will some major component
have to be replaced? Not loaded with cash since we just bought the
house. No warranty from previous homeowner. HELP!?
