Removing the dust bunnies away from the grill and condenser
Defrosted it twice to unplug the drain tube from the freezer
I think it's due to this upkeep that I have never had any problems.
Also, I don't overload the freezer and block the vents and I didn't need all the fancy bells and whistles like some people think they need.
I have ice cube trays I fill and didn't want the extra fuss and maintenance of the "indoor water and ice". Extra stuff usually means more problems. It's just common sense!
It's a good solid refrigerator! Proper care and taking time to maintain things always pays off.
