Just joined the forum for a little technical assistance. I have a York TG9S installed in April 2010. I just moved into the house in March 2011 so this is my first heating season (I live in Philly). My issue started with the ignitor lighting the burners and then the burners would go out after 5 seconds. After a few tries it ignites and goes on its business, until a limit switch trips, which it then goes through the entire cycle again. All the while the thermostat, which has new batteries, is calling for heat. Oh I i replaced the furnace filter a week ago...
So the first issue is obviously the Thermocouple... I cleaned that and also got a new one just in case, however the issue remains on start-up occasionally. So now the other issue the limit switch tripping...
Using a ohms meter I narrowed it down to one of the three limit switches. Then while doing that I realize the condensate collection unit is leaking, where is it leaking, directly on the limit switch and the Thermocouple.
See the attached videos I took a video, you can see the leak and the water dripping directly on the limit switch and the thermocouple. The second link below shows the "temporary" collection "unit" i made as a test to collect the water and direct it again from the Thermocouple and the limit switch.

Video - *.*/watch?*&*&*
To test this theory I increase the thermostate 5 degrees and it ran through the entire cycle without issues, so my assumption is the water leak is the issue.
I guess my question to the techs out there is has anyone every seen this? I am still covered under the warranty so I plan to call Johnson Controls tomorrow to fight for a new condensate collection unit. I say fight because I'm not a HVAC tech so I can only assume they are going to give me problems.
But I am still curious if anyone has ever seen this before?
Thanks in advance.
