How to Clean Refrigerator Coils

Clean refrigerator coils by unplugging the unit, locating the coils (usually on the back or underneath), and using a vacuum with brush attachment or coil cleaning brush to remove dust and debris every 6-12 months.

  1. Disconnect Power First. Disconnect power to ensure safety while working. If your fridge is built-in or heavy, you may need to turn off the circuit breaker instead. Wait 5 minutes before proceeding to let any residual electrical charge dissipate.
  2. Find Your Coils. Check the back of your refrigerator first - most older models have exposed coils here. If you don't see coils on the back, they're likely underneath behind a front grille panel. Remove the grille by lifting up or pulling it toward you. Some snap off, others have clips or screws.
  3. Clear the Work Zone. Move any items stored near or under the refrigerator. If the coils are underneath, you may need to pull the fridge out slightly for better access. Place a towel or drop cloth on the floor to catch falling debris.
  4. Suck Out the Dust. Use a vacuum cleaner with a brush attachment or crevice tool to remove the bulk of dust, pet hair, and debris from the coils. Work systematically from one end to the other, paying attention to the spaces between coil loops where dirt accumulates.
  5. Loosen Stubborn Grime. Use a refrigerator coil cleaning brush or long-handled bottle brush to dislodge stuck-on debris the vacuum couldn't reach. Brush gently to avoid damaging the coils. Work the brush between coil loops and around tight spaces.
  6. Final Debris Sweep. Run the vacuum over the coils once more to pick up debris you loosened with the brush. Also vacuum the floor area and any debris that fell during cleaning.
  7. Finish and Reassemble. Wipe down the back panel or under-fridge area with a damp cloth. Clean and reinstall the front grille if you removed one. Make sure all components are dry before reconnecting power.
  8. Power Up and Verify. Plug the refrigerator back in or turn the circuit breaker back on. Push the unit back into position if you moved it. Listen for normal operation - the compressor should start within a few minutes.
