I can't believe this is true...I install carrier residential split systems for a living. I have a trane unit that is reading a lockout code off the diagnostic board. I cleaned the flame sensor, removed the pleated filter (for good measure) and reset the LED to give it a go for another day. Alas, the system has been locked out again. The status code is reading a lockout from multiple attempts failure to ignite, I can't seem to get it tripped once I reset it. (And lug all my equipment inside from my work truck )
I checked a temperature split and result was at the lower end of the tolerance, HSI looks fine... Honestly I am unsure of what the next logical thing to check is. I work religously on carrier equipment and have never seen this problem.
It all started with a leak around the condensation pump, the installer didn't clamp the hose and it was leaking small amounts. I am worried the board is fried, however I hear things in the inducer motor which leads me to believe there may be some snow inside the housing or something.
Sorry for the long post, I would be grateful for some insight. My buddies at the shop would garentee I never lived it down to come in there saying my own furnace is causing me grief. Embarassing.
