Which freon is good for Refrigerator?
« on: October 09, 2017, 05:22:20 AM »
A few months ago, I bought a second-hand refrigerator for my grandfather. Now, he faced some coolant problems in the freezer. Tell me some good suggestion for solving this problem. I'm a little bit confused in the refrigerant. I searched and found many blogs on coolant. There are many types of coolant. Which coolant is used for solve this problem?

If you are low on refrigerant you have a leak. I recommend a professional to see if it can be repaired and if so the proper repair and service pressure with the correct refrigerant.

I believe some freons have become so restricted that individuals can't buy the freon.  You would have to hire a repair company to fix an older leaking fridge.

Coolant and refrigerant, at least in the automotive industry, are two different things.  Coolant goes in the radiator and refrigerant goes in the A/C.
R-22, commonly used for years in household appliances, is very expensive and is being fazed out of production.
Don't charge the system on your own without some knowledge and a gauge set to see what is going on.
So, like they already told you, call a professional.

By the way, I have a working refrigerator, circa 1934, that uses sulfur dioxide as refrigerant.

Something to look at that isn't refrigerant related is the cooling fins.  I didn't see where to mentioned what the problem your grandpa is having was. 

Some issues can be caused by the cooling fins (typically on the bottom) being too dirty to allow airflow through them. Ironically, this can cause both the unit to freeze up or not cool correctly. 

I ran a concession stand at a basketball arena for many years where we had a big chest freezer we sold ice cream out of.  It was having trouble staying cold one night.  My helper and I checked the spot a filter was supposed to be in and found a 1/2" layer of fuzz, dirt and who knows what built up on the cooling fins.  We removed that and the unit worked another year.  Sadly it died by the next season and was never repaired.

If you haven't cleaned the coils, check them, you may get lucky.

Regardless of the type of refrigerant the unit requires, you're likely not equipped to recharge the refrigerator. It would, no doubt, be a lot cheaper to take your chances with another used fridge than to have a professional service it.

Best advice from someone who made a living in HVAC for many years. Just buy a cheap, no frills, new fridge for him.

   Of the thousand of refrigerators I sold and delivered over the years, I don't recall seeing even one that had a factory installed charging port, Joe [or Jill] average person isn't going to be able to recharge a contemporary fridge, even if they were so inclined.
I spent most of my money on beer, tools and guns, the rest I foolishly squandered on stupid stuff!

I never even noticed the link.  I did wonder about the photo and the lack of any additional posts.  It never feels right when an "out of left field" question pops up and then never gets followed up on.

The whole point is to drive clicks to the site to get ad revenue and raise the relevance on search engines to get to a first page result which increases clicks and ad revenue.
