Got a call for a unit tripping on head head. Customer resets unit but it trips again. Let’s take a look. If you would like to buy me a cup of coffee www.paypal.me/... #hvac #refrigeration #servicecall
""I'm rolling thunder, pouring rain.. I'm coming on like a hurricane.. My lightning's flashing across the sky.. You're only young, but you're gonna die."" pretty sure that's right. lol. Zeppelin rules, AC/DC is right up there with them in my books and so is Lynyrd Skynyrd (yes, as simplistic minimal chords as they played) overall composition and performance :))
Great info! Good to know what types of universal condenser fan motors to keep on hand. I do a lot of small refrigeration and in the process of working on my way up to the big boys! I appreciate your channel!
Pull the bottom bolts/screws off the fan cover before the tops. The tops will still hold the weight and can remove the bottom ones with your fingers once you crack them loose.
i was actually shocked i thought while you were driving good old Dave was going to have to do a condensing unit change out.. i thought the condenser would of been eaten up by the ocean but nope!! damn motor ! plus good old dirty bastard !
Hey Dave , something that's helped me with those annoying tight spots like the lower left fan shroud bolt in vid where its hard to get a full turn of a wrench even with a ratchet is a impact right angle attachment, can put your extensions and whatever you'd need to get to the area. Usually does the job for me!
dirty coil/low airflow will generally cause less load/current draw, since it's not doing as much work. unless it's an ECM, which is likely junktronic design. lol
I just love the condenser unit calls. Got one similar to yours Dave. Unit was working but taking a long time to pull down. My company had sent a tech out for previous call of coil frozen and replaced defrost clock in condenser but did not do a big picture on it (Thanks to Chris for that) and missed the seized up primary condenser fan. I was sent and noticed that when I opened the cover. One of the little 4 inch motors. Got them back up and running. I loved the bubble view while you were working on the unit.
Aftermarket motor , aftermarket blade nice . That motor is a life saver, I have one living in my van 🚐. Could use the angle with the impact for those lower bolts 😀😬. Good video Dave .
3:50 - You named your van "Gina"? 11:24 - I have another "new" trick for you that you may already know: give your trigger a quick squeeze in the tight direction then gently pulse in the reverse to keep from breaking off that set screw. 12:12 - Every fan guard nut I've seen is a 11/32" nut. I bought a Klein Mag 11/32 just for that purpose.
That condenser fan struggled right from the start, when you reset the pressure switch. Watching that sight glass was oddly fascinating as the refrigerant moved slowly through it.
by 2:27 my first thoughts, low ambient/fan cycle switch bad or partial phase loss/low voltage overload upstream (assuming 3 phase supply to unit) but the compressor sound is kind of drowned out and unknow singles/three phase. lol. ok I'll quit guessing and watch :))
1/4" Milwaukee 12v fuel ratchet works great for those hard to get fasters been using a cordless ratchet for years. Way faster then fighting a manual ratchet or wrench in tight spots.
You definitely need to do a video on hobart whatever. They have absolutely no tech support, and will not help you in any way. I'm trying my hardest to have our store to stop selling anything hobart. Apparently hobart wants to make their own services calls, but I get called out on their crap, and sometimes have to tell the customer a lie just to have time to figure out the issue. Bro, please, let's as technicians ban hobart, because they will not help us in the field. If you know someone, or have any ideas that can help with mixers, and any other products hobart sells, please let me know. I do the hot and cold side, and I'm the only technician as of now, any help would be greatly appreciated. Let's talk tomorrow Dave, Friday night talk with all the working dads!! You are definitely the man bro, don't forget about towtrucker, he's another guy that's just amazing at his job, look him up. See you tomorrow night, hopefully!!!
Was that old 1/3hp motor a 1075rpm? I've found a lot condensing units with aftermarket A/C motors on, usually during the years first heat wave. That's when we find who called chuck in a truck when business was slow
8pt sockets are great for those types of set screws and square-headed pipe plugs and older square-headed fasteners.. less chance of rounding them off. doesn't look like there is much room for those units to breathe... also looked like a nice drive
A note on the square bolts... they make 6,8,&12 point sockets. The square bolt has 4 sides, the socket points must be divisible by 4, hense, the 8 point socket is best. In a pinch, I’ll use the 12 point socket but, they tend to strip a tight bolt. For this reason, all my sockets are 6 point, except for the few 8’s I have for 1/4” bolts or the occattional commercial spigot that has a recessed square stud and no handle. That motor as you said was overheated and may have still been a bit tight or a worn cap. Did you notice, the installer didn’t remove the ring mounts? They only come with the motor as a convenience for resilient mounted motors. Your supposed to remove them. When one vibrates off and shakes the thing apart, you will have leaned the hard way. They serve no other purpose.
Great video, in one of your live cast please address the need to LABLE a unit if you change refrigerants. Pizza shop Tuesday calls, regular guy unavailable. Filter drier leaking. Closed my valves, replaced evac, broke vacuum with R22 (manufacture tag listed) As I’m opening high side valve guy brings me a receipt for previous call last February. CONVERTED TO 407F. WTF they NEVER replaced the drier it rusted thru (OEM) Obviously you know how the rest of the call went. Please guys mark it down. 🤬
Dave, should that right hand compressor sight glass been bubbling like that before the compressor started, and even after? (A non-HVAC tech!) Love you stuff and you teaching abilities
We have some units where they put the pump down solenoid on the suction side instead which can cause that bubbling during the off cycle. Probably shouldn’t have bubbles while it’s running though 🤷♂️
Could be a number of things. Start with T stat setting ( is it set to low ). 37-36 degrees lowest. Dose unit have a defrost timer? Is door gasket good Dose unit have clean coils Is the charge correct Is the super heat set right Are the fans operating correctly Is compressor low capacity There’s a ton to check Was the door left open?
@@NorCal-refrigeration I'm in Jamaica and it's very humid, all those pointers you mentioned are fine. I'm wondering if my superheat is too low. Can no load (empty box) pull down too quick and give me such a phenomenon?
I normally work on process or comfort cooling. Refrigeration every once in a while. I can say though....reefer equipment is abused and neglected a lot more than any other form of cooling.
Had to skip at least 3 minutes into your video just to see when you start working. Essentially forcing people to watch 3+ minutes of advertising...just do the work and spare your personality for people who care.
