    Lol you got to love them cheep disconnect boxes 😂😂😂 I was honestly thinking short in T stat wire or a dead short on the contractor to ground…. Great troubleshooting.!!! I always figured a great troubleshooter was worth more to me than a great installer.

    I am mechanically inclined and love to DIY everything. That said I am not HVAC savvy, til a few days ago when I turned on the AC for the 1st time of the seasom when it smoked something within a minute. Much research and a parts cannon later I have a much better grasp of a low voltage circuit. appx $200 in parts from Amazon later I am sitting in a cool dry house and I did it! These vids are awesome for us neophytes. My ex wife just spent $800 with a service tech getting hers back up. :-) Yeah, I know, I still have some anger issues. I won by $600. The problem ended up being son #1 was weed eating around the house a few days prior. He snagged a skinny lil wire at the condenser unit and it looked OK. 3 feet back under the wood box guard the 2 wires were deteriorated and touching each other. I ohmed across these 2 wires up at the contactor coil (wires not connected) and got an open so thought the wires were fine. Always visually inspect everything! Would have saved me the $200 but now I have some spare parts for next time and I got some not quite instant gratification.
    Service techs gotta make a living too but my nature is DIY and spend that money on toys.

    If that low voltage terminal block was dangling I’d say that was the issue….ten seconds later I was wrong. Nice job. Did a nice Bosch yesterday…BOVA-60…when you coming to Florida? I make my maintenance tech watch your videos for homework.

    I just moved into a new home and want to instal an ecobee. I went to the transformer and only have 1 segmenet of 24v through the RED secondary, the GREEN secondary is grounded and doesnt have constant 24v. The GREEN wire is connected to my BLUE C wire. the result is that Im not getting constant power to my thermostat C wire. Is this a wiring problem?

    great video, my transformer has a blue and yellow wire on the low voltage side. the blue has 24v but yellow has no voltage. My unit works fine as far as I know. does that mean I need a new transformer? I have no control board.
