HVAC TROUBLESHOOTING

[@Ed_Tech-Esco]

I had red light on phase monitor & external stop . Ełectrician’s moved feed to a different panel phases needed to be swapped . Couldn’t find TB-4 when I was tracing out external stop circuit , video helped 💪🏼

Had this same issue today. My journeyman and I were thankful for you. Ended up being a bad fuse.

Loved working on RTU's until it poured rain and got gusty! Wished the doors opened as a canopy overhead.

It’s a great feeling to be blessed with such troubleshooting skills.

thank you for watching my friend

[@DvP1]

Buddy! I just did this exact troubleshoot. My search stopped at the phase monitor. Getting power. Tested by jumping y-in and y-out. Phase monitor getting 115.
Thanks for helping. It was my first time on an intellipak.

[@D2DNYAC]

Awesome

[@DvP1]

We went back there. Cleaned the coil and dropped in a new monitor. They are back online.
No blown fuse though. Just a burned spot inside the epoxy fill on the phase monitor. Looks like the fuse won that round.

[@HVACChillin]

Great troubleshooting. I work on trane equipment everyday and learned something today watching. Just subscribed.

[@D2DNYAC]

Thank you for stopping by

[@jamesdunn6976]

I like your videos.
If a 20 amp fuse blew, I would use the amp clamp to check the running current. I'm guessing an igniter or motor is off the same circuit since 20 amps are too much for just control. Then check the schematic for possible high current causes. Check for some circuit that pulls in under certain conditions.

Did you go to Trane schooling? How did you gather your knowledge? You are one tech that I've noticed who works on everything. Large equipment is my end goal chillers, mammoths, rtus large splits but no residential.

Worked on one of these Friday. Alarm was high pressure differential failure, ended up being bad temp sensors on both sides of evap coil. Was reading almost 200 😳 lol

[@D2DNYAC]

Interesting stuff sir 🙂

[@kennethlobo4420]

Like the video U have great trouble shooting skills.just a question would a ground test on the transformer help.

[@D2DNYAC]

Yes has part of troubleshooting the problem surely

[@natsaichigwada6104]

Good video, but just remember all digital inputs are switches and no voltage there are either off or on. Based on Controller logic it knows if closed ok or trouble. Switches on inputs you cannot have voltage they blow stuff up.

Looking at the schematic isn't the phase monitor N/O ? Great work by the way .

[@jonnymac31]

Correct. It closes the contacts when the device is in a "normal" state. If it was N/C and the device failed or like in this case lost power it would allow control power to pass even if the equipment was in an alarm condition.

WHY SUPPLY FAN STOP AUTO MATIC WHAT WAS THE PROBLEM

[@D2DNYAC]

i have other videos on trane rtu you could also watch

[@ookalimanoo]

Conclusion : -- "External" to the intellipak.
-- Internal to the package unit.
"External" supposed to be out of the package A//C as a whole.

[@D2DNYAC]

Agreed 👍

[@DWAYNE2ism]

why that fuse got burned

[@D2DNYAC]

Probably just a bad fuse , because the fuse was replaced and no issues since then!

[@Erikmiles87]

I’ve worked on a ton of these. External stop is typically linked to fire. That fuse pops a ton because the duct detector has shorted to ground. I would have checked continuity to ground, or at least jumped between the circuit at tb 4 personally, but good job none the less.
