Economizer Troubleshooting

[@hvacrefrigeration5204]

You are Very good at economizer system, I would loves to learn more from you sir.👍

[@michaelaaron1134]

Thank you for these videos. Im a residential tech about to start work for a commercial company and while I am good at reading schematics and using my meters, knowing how economizers work will save me a whole lot of frustration. Great videos, straight to the point and informative. A+ instructionals!

[@Dalan612]

Very good explanation. Thank you so much for uploading this. Very helpful for the young bucks like myself who want to learn but don't have good access to training.

[@davidharty3653]

So glad it helps, wish I could've found a simple explanation (video) years ago when I had no idea how to work on them

[@reza49363]

Thank you 🙏, it is not easy to make video and work, you made the economizer so easy to work with, God Bless you

Great content and explanation

[@mrgreen9086]

Great video

[@Johnny2000k]

Awesome video

[@1ndependenceday1]

on some of rtu units the yellow wire is for stage 2 cooling coming from the economizer like carrier or Bryant

[@hvac01453]

holy crap, its not like that condenser coil wasn't pelted with hail or anything...

[@alimanafi907]

Is that condenser motor spinning backward?

[@davidharty3653]

No its not, videos just make it look that way sometimes

[@jayr4980]

Towards the end you mentioned the module is faked and thinks it is ok to open and bring in free cooling. If that were the case why did the compressor cooling cycle on if your sensor is thinking it's cold enough outside to economize?

[@davidharty3653]

With a 2 stage thermostat on a unit with an economizer, the unit will run the economizer for the 1st stage call for cooling and run the compressor for the 2nd stage call for cooling. In other words it will run both the economizer and a compressor at the same time if you have it connected with a 2 stage thermostat. Pretty much all Manufacturers use this logic where you can see a unit economizing and running a 1st stage compressor at the same time.

[@toddiamhvact7386]

so the actuator is bad on this unit and needs replaced?

[@williamgray8277]

How do by pass a york economizer?
