Appreciate you and all who supports my HVAC journey on RU-vid 🙏

Thanks for watching

@@D2DNYAC I'm out in LA California. I will continue to keep stopping by and I appreciate what you do! Keep up the good work!

@Dimas lespier Agreed you are saying the same thing I discovered while troubleshooting, when the suction temperature is too high the system views it as high super heat which can be associated with lost of refrigerant charge! Thanks 🙏 for stopping by old sport

Indeed they do , thank you for stopping by .

@Jermain Carty thanks for stopping by

Good tip thanks for sharing

It runs off space temperature, return air temperature, and supply air temperature also supply air static pressures and sometimes even space static pressures

@jeff grant Thank you🙏 for stopping by

Check this bro. That red bird feeder on top of the unit should be angled at a 45 degree to prevent water from collecting inside of it eventually siphoning into the tubing back to the transducer.

Dope, thanks 😊 for watching

@mark bell Great point old sport! FYI unit ran fine post replacement of sensors

This 100%! I would add the check should first be made at the control, and if OOR at control then checked at the sensor. While you're at the control, you should also check sensor input voltage to help eliminate a control board issue (That is my 1st check). This is IMO how a diagnostician finds the root cause, before ordering any parts, outside of that,... it's guessing. EDIT: the "it's guessing" comment is not fair. It is an "Educated Guess"

@@RJMaker SMH 🤦‍♀️ First of all for most of you if it had not being for videos like this on RU-vid, if you were placed in a situation like this you wouldn’t know where to start, to say that it’s guessing that’s false because there were several steps taken prior to coming to the conclusion! Sensors or logic board and the sensors was the most viable option based on the troubleshooting process.

: The cooling circuit of interest has been active for 10 minutes and the difference in the entering and leaving evaporator temperatures has been greater than the Evaporator Temperature Differential Setpoint for 10 continuous minutes. He did it right. The MCM is good because it’s getting the readings and you know by the valve given one is not reading correctly. You can verify buy resistance but really no need. Good techs don’t always waste time going through all the steps in the troubleshooting process when they know which ones can be skipped.

@@globaltecnicianworldsbest3031 I'm not "most of you", and yes I'll give you it was an ** educated ** guess. My point is, in this case there is NO reason why you can't absolutely know what the problem is before ordering parts.

@ Dimas lespier Like the the one in the video 😆

Yes sir

I have several other troubleshooting videos with them!

Send me link please my new AMIGO

🤣😂

Thank you for stopping by

I just had my first experience with them. Question: where is the outside air sensor physically located? I've found where it's wired inside the electrical compartment from the schematic.
