Clean refrigerator coils
Dust on the condenser coils makes a refrigerator run longer to stay cold. Some models need the coils brushed off now and then; many newer ones never do.
Last reviewed against 2 official sources.
Who this is for
Owners of a refrigerator whose manual says the coils can be reached and cleaned. Check first: GE says most of its refrigerators made since 2001 have a condenser that needs no cleaning.
How often should I clean refrigerator coils?
No official interval. GE gives none and says to clean more often with pets that shed or in a dusty spot such as a garage. General guidance: look once or twice a year, and any time the refrigerator runs but is not cold enough.
