If you buy them through a dealer that will give you a 90 or even 120 day guarantee, then it can be a good deal. True is a decent brand, but then again, so is BMW. No one says I can beat the crap out of a BMW, hot wax it, and sell it before it starts to cost me major repair bills, right?
Here are two major problems with used refrigeration equipment:
1) Insufficient amperage. Generally problems concerning this are found with smaller units. Say the max. draw for the unit is 12.5 amps, and you have one or two other appliances plugged in to the same 15 amp circuit. This puts considerable stress on the compressor when it starts up. After a year or two of this, the compressor motor starts to weaken. Major repair bill.
2) Corroding coil. Compressed refrigeration gas is allowed to expand in a coil, or radiator inside of the fridge cabinet. This is generally made of aluminum, better ones with copper and aluminum, and best with copper and teflon coated s/s. A lot of things will corrode aluminum, copper, and even s/s. Major culprits are:
a Vinegars, salad dressings, citrus juices stored without any coverings
b tomato products stored without any coverings
c Spicy and chilli based products stored without any coverings
d The worst: Yeast doughs and fresh cake yeast. A lot of cooks and bakers will allow dough to ferment/ripen/proof in the fridge. On a cheap fridge with aluminum coils, it will eat the coil within a year.
Once there are tiny, pin-prick holes in the coil, gas escapes, the fridge can't keep temp., the compressor runs constantly and you are faced with replacing the coil or tossing the fridge.
If there are problems with a used fridge, they generally will show up before the 3 month guarantee. Never buy used from a dealer who can't give you a minimum of 90 days.
After 35 years in this business, my first response to buying refrigeration is to always buy new..................
