Hi, I'm new to this site and I have some questions about my system. I'm not familiar with the terms about these units, so please be patient with me. The heat in my home does not come on and the funace does not come on either. I went outside to the hvac unit and my dog had eaten the brown wire ( I think it's the control wire.) with a white and red wire in it. The wire went from the house to the unit. Also there was a blue and yellow wire hanging from the hole on the bottom of the power supply hole( See HVAC Pics Below). The Unit is a Trane XE1000. My furnace is an electric furnace. Please help me to repair this and let me know if you need to know more information. Thank you so much for your time.
