Haha, your brain works like mine does! Remembering some random completely obscure detail from years and years ago that ends up saving the day! Love it!

I would do the same. Tell the customer what you found, advise them to keep an eye on it, tell them you'd be more than happy to sell them a bunch of parts, but you don't think it's necessary at this time! Customers love honesty!

My guess?? A… electric motors running at low voltage will heat up.. B caps will drop as voltage drops. I think it could have been a combination of both an finally the condenser fan motor shut down on thermal overload, which turn would cause the compressor to run high-pressure and lock out..🤷🏻‍♂️ only guessing here with What evidence is presented… but I think your spot on !!

Chris, try to take care of yourself. You can’t help your customers if you get burnt out. ❤ Sending love from Australia.

The tone in this man's voice I feel like he's like a er doctor on cooling heating 💯

[Critter]

Work at a restaurant. Either the BOH or FOH AC works. Usually never both. It’s hot in Tennessee.

[alext]

I completely agree with your logic Chris, I wouldn’t have done anything differently in this situation. Thank you for another great video! 👍🏻

Pace yourself my friend. Like the infrastructure in the U.S., quite a few pieces of equipment have outlived their useful life and you are the caretaker. But there is just 1 of you ! What the state, nay, the country needs is interested individuals like yourself to get into the trade and help things out ! Used to live in the Detroit MI area and in the 60's there weren't none air conditioning. Until we got a 10.000 BTU sucker for a window, . . ..on 60 amp service. Your skill with the modern machines leaves us mesmerized ! In this VLOG I believe you did the appropriate course of action. Cheers.

Wish you worked in the Fort Jackson, SC area. Last week, I happened to be outside my Barracks and heard a short, and see the smoke in the AC unit, and I saw the flash of the complete failure of the power panel which also triggered whole building power outage. They ended up hooking up a temporary unit to the system. Now, the AC in the DEFAC is also out, and they also set up a temporary unit for the time being.

I am not a HVAC technician but I know how heat can affect electrical components changing the cap was a good call also when you are good you gonna stay busy since you are so tired that means you are good

[andrewkarchner]

Keep it up Chris, summers been rough here in Pa also . Prolly nothing like there

[manxman]

tip - stick labels on the units for dates and purpose

Great video, Chris, packing so much in. I love listening to your thought processes and find them informative and insightful.

I have a couple of thoughts:

What about using thermal imaging to record temperature rise in the condenser fan motor? It would show a bearing heating up and how hot the motor was getting even if the current draw was within allowed limits.

The run capacitor that you replaced could have had intermittent failure. I've known capacitors to partially fail internally and suddenly not perform at all as required, usually due to a voltage surge or spike. When the power is removed from the capacitor 'self-healing' takes place and things appear perfectly normal until the next voltage spike and the cycle repeats. As the capacitor internal condition worsens it takes a smaller an smaller spike or surge to make the problem suddenly appear. Eventually, no more self-healing takes place and the capacitor goes bad for the last time. It's possible a temperature rise may be observed in the capacitor and thermal imaging may help discover this. Otherwise, the only way is to use a dedicated capacitor tester rather than rely on a function built into a multimeter. A proper capacitor tester can reveal far more about a capacitor than a simple measure of capacity. For example, the ESR or Equivalent Series Resistance of a capacitor is a very useful parameter in helping determine the internal health of a capacitor. Any reputable manufacturer will have the full specification of a capacitor available and if they don't I would want to know why and consider using a brand that does.

Didn't yawn, but I *felt* the tired.

[johnchristou]

Ive seen out of spec caps run the fan backwards. Also seeing light through the coil doesnt matter on a micro channel as much as tube and fin. Also good to check the pressure switch itself. I block off coil and watch guages to see if switch cuts out prematurely. Good stuff👍

[djenson]

Funny how you have undervoltage issues there. In the UK, where the target voltage should be 230V, the abundance of solar and lack of AC demand means the voltage can be seen as high as 258V where I live.

[carloshilarionvazquezaranda]

Buenas tardes Chris, como siempre un excelente trabajo y con todo el ánimo de salir adelante ésa actitud que todos deberíamos de tener es admirable en tu persona. Por otro lado si te miras cansado y no me hiciste bostezar Jajaja, Saludos y abrazos a todos ustedes deseando que estén bien y que tú descanses para que recuperes energía.

Love your channel. I like how you put everything in simple terms.

[HVACRMICHAEL]

Yeah, I’ve found if the caps are going bad the wind can help start the motor and you’ll get intermittent problems, I always make sure when I test the condenser fan motor and suspect a cap the blade is stationary.

Id like to see how that RTU runs on a 100+ degree day. I think you did your due diligence. Definitely needs to be monitored.
