Kitchenaid fridge
I have a 1 year old Kitchenaid side-by-side fridge along with pets. Very happy with fridge and pets. I don't recall what the owner's manual says but I periodically check the condenser coils jammed underneath the unit. They were full of dust and pet fur.
Vacuumed it out - fridge was happy. However, next time I think I'll take my Swingette and attach two hoses to it; one in the intake and one in the exhaust. I'll blow the junk out from the rear and suck it up from the front.
Don't know if it'll work but I'll have fun trying.
