Thank you for the manufacturing info, Senpai. Can you reveal your source? My only agenda is just wanting to know information like this when I buy an appliance. My unit is eight (8) years old, and when it was five (5) years old in 2010, it couldn't maintain the refrigerator temp (refrigerator and freezer have separate systems, as you probably know). The diagnosis was a refrigerant leak so somehow I ended up with an entirely new cooling system. To be on the safe side, the tech installed a UV dye in the refrigerant so that he could locate the leak, in the event he was called back for another leak, but it never did fail to maintain temp again. Would be nice if it lasts for another 8yrs now, knock on wood x128, but probably the control board will go bad. :tongue:
May I ask you a refrigerator question, Senpai? Everyone says to clean the coils annually or semi-annually. I have not cleaned my coils since installation, eight (8) years ago. The coils are covered with dust on the edge of the coil array where the cooling air enters, but if you look back 1/2 inch or more, they are pretty clean and nothing shows on my finger. Our house was renovated at the same time the unit was installed, using Milgard plastic windows and fiberglass doors that are almost always closed. No kids, either.
Do you have any practical knowledge about whether I can go another eight (8) years under the same conditions without reducing the heat transfer capability of the coil/rectangular array of wires? I understand that the capability is down a little from time zero, but is it really enough to reduce the life of the appliance noticeably?
I am aware of all the sites and persons that say clean your coils, but I think it might cause more trouble than it's worth, under the "if it works, don't fix it" principle. If I loosen a coil array dust particle w/o vacuuming it, might it not do something to the condenser motor over time? I was hoping you had a case of two (2) units, one that was cleaned and another that got its coils somewhat dirty, comparing the unit lifetimes.
Thanks so much for getting back to me, Senpai.
