LOW ON REFRIGERANT? LESS THAN 1% CHANCE

How much refrigerant does a Refrigerator have in it?

In most cases from 4 oz. to 8.5 oz.

How much refrigerant does a Central Heating and Air Conditioning unit have in it?

In most cases from 60 oz. to 100 oz. or more.

So if your refrigerator is low on refrigerant it will have a different diagnosis to it than an Air Conditioner. So if you're a former HVAC technician or you are a current HVAC technician you might assume that your refrigerator or customer's refrigerator is low on charge because there's frost not completely covering the coils. It's low on refrigerant, right? NO! Refrigerator's and HVAC are different machines and operate in different atmosphere's. So don't assume that because your refrigerator is low on a full charge that it's an easy fix.

If it's low, it doesn't cool at all. That's how the refrigerator operates. If an HVAC system is low it still could have pounds of R-22 or R-410a inside helping to keep a relatively cool atmosphere. So next time you think to relate HVAC to your refrigerator, don't. It's a classic mistake. The sealed systems are different and diagnosis can make you think in the wrong direction if not careful.  

If any system is low that means there's a leak, which is bad. Coils most likely would have to be replaced to solve the problem for sure. In any case we always laugh out loud when someone says, "I think it's just low on charge." Our response always is, "I hope not, because that means it could get expensive to repair."  

So before you assume a leak which is usually not the case let the professionals take a look first. Out of a 100 refrigerators we look at that end up being sealed system problems only 1 will come away with a diagnosis of a leak.
