Think I might have blown a fuse or something cause nothing happens when I touch those wires together
HVAC Technician: airheatman, HVAC Technician replied 2 years ago

You did not let anything touch the blue C wire did you?

Ask Your Own HVAC Question
Customer reply replied 2 years ago
No not that I'm aware of
HVAC Technician: airheatman, HVAC Technician replied 2 years ago

OK if fuse blew you have a short in control circuit somewhere.

Red 1s 24v power.

Connecting red to green should energize fan relay

Connecting red and yellow should energize contactor in outdoor unit.

You may have to get a meter next or call in a tech to see why we get nothing at thermostat

Any techs you recommend in the Dallas area?
Customer reply replied 2 years ago
Because now there is no heat at all
HVAC Technician: airheatman, HVAC Technician replied 2 years ago

Best bet is going to be to grab a phone book and look for local heating and ac contractors to find nearest one .I am not from the area so not familiar with local companies.
