One of the most chill, laid back RTU troubleshooting videos I’ve ever seen. I don’t always deal with RTUs so when I get called to one I get a little intimidated. I’d like to be this relaxed with them.

Great video you learn a lot by tracing out the wiring in any equipment.

I appreciate this so much , you calmly , precisely basically went and explained everything towards determining the troubleshooting methods and what things do as well as explaining the part what was the issue. As a young technician this video is so helpful and education . You got my subscription 🙏🏾 , keep up the great videos for us young technical entrepreneurs to learn from .

Those are fairly simple to rewire through the safeties back to the contactor coil to get the customer some cooling in the meantime boss Really good find 🙌

Yep on the trane units you have to trace out the wiring because the diagram is always gone just small one little line and it is never the section you are having trouble with

On the contactor, L1 L2 L3, each one should be 120v to ground?

Depending on your voltage but in this case I believe yes. It's kind of wonky but for 208 power each leg of a three phase 208 is 120 to ground. But if you take each leg to one another you should get 208. I hope that makes sense

Are there any special precautions not to create a short circuit and prevent from damaging the board?
@gendronhvac-r1269

I would say yes, 1) The unit must be shut down. 2) You cannot let the board touch any metal. I have seen people lay the board on top of the unit, don't do stuff like that. If possible remount it in position. Those circuits in the board can short if they touched any metal, Mounting it up properly before starting is preferable. 3) If you're going to touch metal to the board. Such as a Screwdriver for instance the remove the harness. Just touch The tip of your screwdriver to some random piece of metal. If it has any electrically stored energy it will be dispersed. This is not a big deal but this is how people work on computer circuitry. I would say that's a good start I hope that helps.

What is the actual method to verify 100% that the board is bad without swapping from another unit?
@gendronhvac-r1269
3 ай бұрын
As far as I know there is no like 100% percent method. At least in my experience, I am not the end.All be all over frigeration, so there could be people who are more experienced in controls.That could give better advice. But theway I do it without Swapping A board if that's not available to me. Typically, the owner's manual will have an order of operations.Or if you call the helpline they will tell you the order of operations. For example. This is just an example and does not apply to this train unit.Or any. 1) If the indoor temperature is over seventy five. 2) Refrigeration will turn on. 3) But if it's below seventy outside the economizer will engage. Now let's say if it's 90 degrees outsid. The room inside is 80. And everything is working correctly on the unit but it's not engaging. The fact that it does not complete the order of operations but everything on the unit is working correctly including the t-stat. This would make me take a closer look at the board. I would test the sea if the board was outputting the proper voltage. I would also remove the board and check for corrosion and rust And damage. I hope that's helpful.It's definitely not a hundred percent but it's what I do. God bless

@@La2venida transducers are an electronic device. Senses the pressure, Has to calculate and convert into analog signal, which needs to be processed by a brain (controls). Pressure switch is nothing more than a light switch; pressure simply closes the switch and completes an electric circuit. Electronic and electric are nothing alike. Pressure switch is simply a safety device within a circuit, to protect components such as a compressor. Pressure gets high, high pressure switch opens the electric circuit and nothing works; just like your finger hitting the light switch and the room gets dark. A pressure switch cannot tell you what the pressure is. Transducers are very advanced.
