Connecting C wire in the furnace

[coolercity]

Hi,


I took off my old thermostat and see a Rh/Rc, W,Y,G and a blue and brown cable not attached. I go to the furnace and see the blue and brown cable not attached to anything, so I assume I can use this for a C cable? I'm not really sure where to attached the cable on the furance though and what type of wire i need to attach? The wiring plate on the furannce doesnt look like the ones in the videos. Could any of you check out my pictures?

Thank you in advance!

I found the manual to my Furnance if that helps: http://appliance911seabreeze.com/HWC...all_models.pdf

I do not see it in your pictures but on page 14 of your attached link there is a blue wire from the transformer that connect to the GND (Ground) terminal. Connect your common wire from the thermostat to the GND terminal.



What thermostat are you installing?

I have the honeywell $100 wifi thermostat

I'm kinda new for furnaces (obviously). I'm not sure what a transformer looks like and there are several blue cables in the furnace. Any hints?

Thanks!

Make sure that you reinstalled the furnace door. On Most furnaces the door has a switch that will prevent the system from running if the door is not installed.

Crises adverted, one of the cables got loose on the connection to the thermostat.
