Like how you get right to point. Right to work. No long ass boring stories about how your grandpa and daddy helped you get into hvac work and what it means to you. 👍👍👍👍👍 thanks
You should always check for a short or grounded compressor or fan motor before replacing 2 blown fuses . No sense in blowing more fuses. I guess 37.5 years running HVAC service and dealing with so many blown fuses it becomes second nature. I actually do not see many fused disconnect boxes anymore just on older HVAC equipment sometimes. Keep up the great work and videos.
Sam Thank you big time. I learn so much from your videos, you are a great instructor. When the new fuses popped, did you have to keep replacing them ? It just shows how the best tool in your bag is your brain backed up by your senses : sight,sound,smell, touch. You didn't require many tools for the diagnosis.
When I first entered the industry I was under the same impression. I honestly believe that once you have your method of diagnosing it is sufficient enough through the process of elimination to find the issue or issues. Turn on thermostat. Does it turn on? Does the blower @ return turn on? Did condenser turn on? If yes... check refrigerant levels. If no... check contactor, diagnose capacitor etc. The best training advice I give my guys is to always separate the return from the condenser. If you can do that then it is much easier to diagnose when out in the field. The more I post channels and get responses like I did from you it shows me that my channel is effective. Once in a while you get that one HVAC company employee who will attempt to discredit me. For them it's not about helping people it's about money. To them I am like the magician who shows how the trick was done step by step and once I expose how easy it is to diagnose the issue... these guys get extremely irate and post negative comments. What they dont realize is that I have people like you who encourage me to continue to post my videos... the negative comments just add fuel to the fire... 😅 Dont tell them I said so! 😁
One question, please. Wasn't the ground wire that was pinched under the fan already grounded to the motor case and the frame? I am learning trying to learn HVAC, and can't quite grasp how the green ground wire caused a short if it was already grounded to the fan motor case before it was pinched. Thanks for the explanation.
Hi my ac filter is new ...air handler and compressor fan are both running well full speed but temperature does not move below 80 even though I have the thermostat set at 78. Only at night temperature falls to 78 as set on thermostat but then thermostat never turns unit off. Unit runs all day but during daytime inside temperature stays at 80 even though thermostat setting is for 78. When at night thermostat does read 78 as desired then thermostat never turns unit off. Any ideas ? Outside real feel temperatures are well over 100 in Florida at this time where I live.
The ground wire cannot "short to ground" by pinching it. The ground wire is shorted to ground when it is installed, so the pinching did not cause the short. The motor is grounded/shorted internally and locked up. That is what is blowing your fuse......not the green ground wire.

Great Video Sam Thanks for showing how you have a systamatic approach to diagnosing.

Nice video on isolating where the ground is coming from.

Awesome troubleshooting skills! Thanks for taking the time to share them with us! Sincere regards!
Nice video man
Outstanding tutorial.
Great clip sharing

You must've had a close air damper or something like that in your duct system
Good job sir! Keep up the great work 👍
Is it true that to properly diagnose an AC unit the outside temp must be warn or hot?
The ground wire cannot "short to ground" by pinching it. The ground wire is shorted to ground when it is installed, so the pinching did not cause the short. The motor is grounded/shorted internally and locked up. That is what is blowing your fuse......not the green ground wire.
Exactly, dudes fundamentals are lacking

Good job at making it look so easy.
Great trouble shooting
Great video
nice i like..
Nice
