How do I know if a fridge needs a freon Charge?
« on: June 16, 2011, 12:54:52 PM »
Hello, I have come across a few refrigerators that do not get cool enough.  What are the main causes for a fridge not getting cold enough and how do I know if it needs freon?  Thanks for your help

Get the access panel off the evaporator and see if frost is covering all the coils.

Okay if there is frost is that mean I am good to go?  One of them will frost really quickly at the top and the person I got it from said he thinks it needs a recharge.  But, doing a recharge isn't that common is it.

Let it run for a while and make sure there is frost on all the coils, partial frosting indicates a low refrigerant level.  While you have the panel off make sure the fan runs as well, doesn't matter if it gets cold and you don't circulate the air. :)

You connect your refrigeration gages to the system low side and high side. That takes the guess work out of the equation. I haven't seen any refrigeration police around here but if you "charge" a system knowing it has a leak (size matters) the EPA can fine you up to $2500

My guess is that if it is low on refrigerant than the fridge does in fact have a leak?  So if the fridge is low on refrigerant then I have two problems, one I have no refrigerant and two there is a leak somewhere in the system, correct?

Correct, a refrigeration system does not use refrigerant (Freon) like a car uses gas. If a refrigeration system is low on refrigerant it leaked out.

So short answer.  If there is a refrigerant leak, scrap the repair??
