Finding the leak and fixing it would be one of your best videos! Do ti!

R134a also works in older R12 Just charged a 1948 refrigerator Works great

Great video. You are a great instructor. I wonder if you would provide a full training on refrigerator repair.

You provide much detail on removing all air in lines, most just say, let out the refrigerant for a second. The advice on pressure and clogged cap tube is helpful and I did have that issue too. I never heard of just adding an estimated charge based on full charge. I am buying more refrigeration gear as I get the funds to do so. Thanks

Very good presentation. I worked in the field for many years on a lot of large equipment running AZ-50 at 25" of vacuum. When you get a leak in that, you have a major job on your hands! I wish I had the tools that are available today, it would have made things a lot easier. Just remember, when you think you've seen it all, you haven't!! You will make a good instructor!!

Benjamin is so helpful. I had success with my Maytag after watching this video 3 times and planning ahead! I had to modify my R134 gauge set to have an R12 line to the piercing valve. I bled the blue & yellow lines before opening the pierce service port. Sure enough, it was at -12 PSIG (pounds per square inch gauge). Gradually, very slowly, I added R134 until the low side rose to +1 PSIG and closed it up. Add some R134, turn off the supply, and let the pressure settle. After charging, over the next 4 hours the freezer gradually decreased to -5 degrees. UPDATE: The charge lasted 10 months & I am filling the system again. This time I added more technology to the repair. Using an HBN electric meter, amps were .67 before I added R134. However, when I measured amps 6 months ago, it was .74. I conclude that the amps fell because there is less R134 in the system causing less resistance in the compressor. When I refill the compressor, the amps should return to .74. One thing I disagree with Ben and that's how much R134 to add. If u add more R134 than needed, the suction line will freeze. On my Maytag, +1 lb of low side pressure when the compressor is running, is correct.

Excellent video. I would love to see a video of these gauges in full operation. I have a cheep set of the harbor freight ones. Something about Gilligan and primitive come to mind.

Awesome timing Ben. For months my under cabinet ice maker has been making less and less ice. Then no ice last week. I half knew how to do this, but I put the piercing valve on and just tried to dump a can in. I didn't realize to bleed the line or that it would be such a slow feed. So I put my vacuum pump on it, drew it down and started over with a new can. Used my kitchen scale to weigh in 4ish ounces. Been making ice like new. Thanks.

R134a refrigerant is a single component and does not need to be inverted for liquid filling. It is safer to just use an upright refrigerant tank for gaseous filling, because the compressor inlet must be gaseous. The suction of liquid refrigerant into the compressor will damage the outlet valve.

I'm pretty sure for automobile air conditioning you don't want liquid dumping straight in...besides every small can I've ever used eventually gassed off and emptied into the system. Even the large bottle i used when rebuilding some automobile air conditioning compressors eventually completely emptied. So I was very surprised to see many techs inverting the bottle. Seems counterintuitive to me. My Machinest Mate at my unit in the military would sit the large tanks in a trash can with warm water. Someone in the know should clear this up. Thanks!

R u sure? I discharge R-134 into an old propane bottle that I evacuated. If I open the valve while in the upright position, gas comes out. If I invert it, liquid refrigerant comes out. I am sure of that. Even the container says liquid one way, and gas the other. So I respectfully disagree. And I have been charging automotive units since we were using R-12.

If these appliances need a recharge, there is a corrosion pinhole leak somewhere on the aluminum tubing. Over time aluminum tubing in insulated wall sweats reacts and causes that. Also aluminum connection to steel or copper tubing corrode. When charging, use the amp meter to not go over the compressor rating of a full charge when appliance is running.

Great video! But I hope you did not replace that freezer. Freezers of that size are very difficult to find now. And the cost of this repair is 277 times less than the average new 20 cu. ft. upright freezer. I watched this video because I live in an apartment where the PM won't repair or replace the failing refrigerator. I wanted to understand what could be done to repair it. Thanks to this video I discovered I can buy a used $50 refrigerator in good condition and just recharge the silly thing.

Very good, to the point, plus sensible but important little points like the bleeding process. Tire of the ford training fake (non)informative videos that are nothing more than just ads for their bs school.

well done job ! Very precise, proper ,accurate and clear !

You are a wonderful teacher!

Torquing to full stop with repeat insertions could cause leak. If you rely on threads to locate the seal point it might not return to full sealing force (needle to tube). For example: my piercing valve is 3 turns stop-to-stop ymmv. Go in ~2 1/2 turns to pierce, then back off and charge. Then in to light torque to ~2 3/4 turns, which is plenty for the 30psi resting pressure. Then you know the seal force is point-to-tube instead of thread-to-thread. This also allows for increased depth needed for future recharges.

Great video! Thanks

I don't recommend those piercing type valves as a permanent installation. They leak as well. Use them to recover, then braze in some Schrader valves.

Nice job. Probably should take that piercing valve out though and braze in a shrader valve. That might slow the leak down too. They say those pircing valves vibrate loose.

Great video! Though it took me a minute or two realize that this wasn't actually Elon Musk showing us how to charge a fridge. ;-/

Very thorough video. You definitely should have pinched off the process stub, removed the bullet valve, and brazed it shut. Those valves are always going to leak. The process for r290(propane) is exactly the same. You just have to be sure to vent out the old gas in a well-ventilated space, pull a good vacuum and charge it back up. It is such a small amount of r290 that you done have to worry too much about it’s explosive properties. But never leave the piercing valve on a system.

The valve allows him to come back and recharge it. Remember, this isn’t a professional perfection job the system wasn’t evacuated. he’s telling people how to add refrigerant for no money which could be very helpful to a less fortunate family 🙂

since you have the digital gauges and clamps, would it have been best to measure the superheat at your operating condition vs weighing the refrigerant?

Great instructions!

You’re so cool. Love your videos.

very impress how well you explain the hole process ....thanks for share

Great video. I have a quick question for, you maybe you can help. I have a small wine fridge that I suspect is low on refrigerant. it uses r600a. what psi should I fill to? Is it the same as 134a typically? 1-2psi positive pressure on low side?

Brilliant young man. Thanks.

I think that your videos are very informative and useful the way you explain yourself its easy to understand and in some of your videos is easy to understand what you are doing and please keep making the videos as like I said the way you explain and I saw another video where you explain how to connect the hoses and how to charge the system thank you for your videos 😂😂

Great Video I am going to try it out.

Ben I just watched your video about charging 134a to a freezer that has small leak from 3 years ago. I believe I see where your leak may be. At the end of your process tube it looked like it had been crempted off but no weld. Just wandering.

Nice, I refresh my mind. I wish I see what is the actual High Side and Low Side Pressure. I read about 6psig when you charge it for Low Side. Other video says 2-3psi is enough.

Awesome! Thanks!!

@Benjamin Sahlstrom is there a reason you would not want to use one of the A/C stop leak ~type products? I understand that over charging with one might cause a blockage or at the very least is limiting the capacity of 134a in the freezer. However, if it works as advertised and would stop a slow leak, then what would be your concerns with using such a product?

Good explanation of the process.

good job! thank you

Your equipment is very good.

I got a lot of info from the video thank you.

What are the normal on-off-on-off-on-off times for the compressor under normal fridge running? Also, what about stop leak for very small leaks?

Going to try this with a R410a dehumidifier. Wish me luck!

Good video . But a question . Can you let piercings valve in after charging epa type 1 ? And vent de minimis open close open close ball valve?!?

HI, I noticed you have your freezer in an unheated building. Do you have to install a crankcase heater on the compressor, to keep its oil warm? Thanks Friend

Your video was excellent from a practical point of view. However the way you purged your hoses contaminated your tank. If you repeat that incorect purge you'll contaminate your tank more with each service call. Before opening valve on tank, both valves on gages must be open and the distal ends of both red and blue hoses open to atmosphere. Loosely attaching blue hose to bullet valve and loosely attaching unused red hose to back of gage will accomplish this. Now open valve on tank and quickly tighten blue hose to bullet valve, quickly close blue guage valve, quickly tighten distal end of red hose, close red guage valve. Charge 5 -6 psi suction but no more than 10.

@robertlandry5733

The valve on the tank is one way and can not be contaminated. They do that so the bottles can not be refilled. The exception is a recovery bottle.

Your Art of teach are verry nice!

Great Video!

Great video. But novice question: in this video you suggest suction pressure at 6-7psi. My fridge was powered down in hot climate for 9 months, and when I turned it on, it did not cool. Since I did not know the amount of remaining refrigerant in the system , I probably overcharged it to get to 7psi on the charge valve, and put ~6 (?) ounces of R134 instead of recommended 5 oz from the label. So now the fridge is working better than perfect, but the suction pipe gets frosted nearly up to the compressor. Is it dangerous? And if so, is it possible to remove some refrigerant from the system and how? I have seen other videos where the recommended suction pressure is ~2-3psi. If i try to bleed it, it bleeds with oil also, which is not good...

What a great explanation! Just one question though as I might have missed it but was the compressor running as you added the refrigerant?

Nice, great info...,helping my family save $$$

Will the A/C stop leak products work with something like your slow leak? Or would it make things worse?
