I recently bought a house with a Trane XE60 Furnance. I discovered that the furnace is not working. The Trane XE900 A/C unit on it works just fine I think there is something wrong with the wiring on the White Rodgers 36C03 valve.
What I see is that The White Wire from the TStat is not terminated near the Relay.
On the Valve the TH goes to the Load limiter then to the TCO and VSS and to the transformer where it meets another white control wire.
The TR goes straight to the transformer
The Th-TR has nothing on it.
Now, could any of this have anything to do with the Pilot not staying lit? I personally don't think so but when I replaced the TC it still did not work so I am afraid the valve is shot.
Thank you in advance.
