York gas furnace - how do I find terminal C?
Hello,
I have a York gas furnace model P3URB12N07501B
I purchased a Honeywell thermostat that requires connection to c wiring. I had an extra blue wire that canbe used for it.
When I was looking to connect the blue tote terminal I noticed there is a bother wire that is already connected and which is not part of the wiring that goes to the t hermostat (maybe part of the furnace). Can I connect the blue wire to the c terminal even though the other wire is also connected.
Thank you in advance for your help
