Hi.
I have a Trane TUX060C936B3 model furnace and now that the weather is cooling I discovered it won't fire for heat. A/C worked this summer, but we didn't have to run it all that often.
Details:
-turn on heat at thermostat and hear the click...but nothing happens at the furnace, no clicks no noise of any kind. power and gas are fine. fan comes on when switched from auto to on.
-after a day or 2 of running the A/C there was water on the floor around the furnace. It was coming from the hot side drain, not the cool side drain.
-was getting 3 flashes which is a pressure switch problem according to the sticker on the controller.
-pulled the vacuum lines off the pressure switch and water dripped out!!
-reset ignitor switch with vacuum line off the pressure switch and this time the ventor motor fires up...but nothing else. now light on controller flashing normally.
-drained water out of the pressure switch and vacuum lines and now the ventor motor comes on, ignitor clicks, see the orange glow but the burner won't fire. cycles through this 3 times and then fans come on and light flashes 2 times indicating 'system lockout (no flame) check line poloarity".
-there was a bit of water in the ignitor from the vacuum lines... so last night i left the vacuum line off hoping anything still in there would evaporate. it's clicking on so it's getting enough pressure in there but it's not sending gas to the burner.
My brother was over, handier than i am and suggests that if there's still water in there that could be causing the problem. He things that the A/C drainage had backed up and water came down through the system, but we couldn't get at the drain because the pipe is plastic with no clamps...it will have to be cut and investigated before we consider running the A/C again next year but in the meantime I just need heat!
Any ideas beyond letting water evap in the ignitor?(is that the right term? it's the little box that has the on / off switch that sends the gas to the burners). Forgive my noobiness.
Thanks
