How difficult to refill freon in fridge (Kenmore 795.73165.610)?

We have a Kenmore Elite refrigerator model 795.73165.610 we purchased less than 3 years ago. The compressor recently crapped out, which was confirmed by a local repairman who also enlightened me to the wonderful insight of LG’s legal issues with their refrigerators, but because this is technically a Kenmore fridge, they are not liable for this. His two offers were to replace the compressor and recharge the fridge for almost the original cost of the fridge, or just refill the freon which could last a week or a month, no way of knowing. We have picked out the fridge we want (GE Cafe Series), but it would not deliver for two months.

To wait for the fridge we want, I am considering attempting myself to refill the freon. from what I’ve gathered, it’s simply a matter of purchasing bullet-piercing valve and the correct freon to add to the line. I see some sites saying it’s best to drain the existing freon with a vacuum pump in order to not overfill.

Any advice will be appreciated!

Normally you need EPA certification to mess with refrigerants, but this is no different than people messing with their car ac systems.

If your ac system is pretty much empty, then releasing the last few psi is ok. Its r134a which is pretty much inert and not ozone-damaging, plus if its just remnants of the charge (NOT the fill charge) then its considered a diminimus amount by the epa and thus they don't care.

Once you do, I'd recommend pressure testing for 30m to see how bad the leak might be. If you see a noticeable drop in pressure (1psi+ is noticeable and means the charge won't last very long) then it won't really be worth it.

If you aren't going to do that… then yes, purge the system, pull a vacuum, and weigh the charge back in to the weight specified on the data tag inside the cabinet. Might want to add 0.5oz to that to compensate for refrigerant that will be left in the line when you do it. Go slow. If charging with container of refrigerant upright then just go by weight, and charge til you're there. If you're charging it as a liquid then you need to make sure to go SLOW! Because you don't want to flood the compressor with liquid refrigerant because you'll wash all the oil out.

On a side note… if your compressor took a crap and needs replaced then how can recharging the system keep it running? Either the compressor is bad or it isn't… I'm confused

Also, try and look for piercing valves that are less likely to leak over time.
