Refrigerator
Your refrigerator is the one appliance that never turns off â and dust-caked coils are the reason its compressor works harder than it should, every hour of every day, to do the exact same job it used to do with less effort.

Answer a few quick questions and get a personalized diagnosis from the HomeShape Repair Coach.
Select your type
Most refrigerators made in the last few decades vent through a removable grille at the bottom front, tucking the condenser coils behind it. This is the easiest configuration to clean since nothing needs to be pulled away from the wall.
Maintenance tasks
| Task | Cadence | Skill | Time | Consequence if skipped |
|---|---|---|---|---|
Vacuum the condenser coils Remove the bottom grille and vacuum with a brush attachment | Every 6â12 months | 1 ¡ Beginner | 15â20 min | Dust-caked coils force the compressor to run longer and harder, raising energy use and shortening its lifespan |
Clean the bottom grille/kick plate Wipe or vacuum dust and pet hair off the grille itself | Every 6â12 months | 1 ¡ Beginner | 5 min | A grille caked in dust and pet hair restricts the very airflow the coils need |
Check and clean the condensate drain pan Locate and wipe out the drip pan beneath the unit | Every 6â12 months | 1 ¡ Beginner | 10 min | A dirty drip pan is a common source of musty odors and mold growth |
Inspect door gaskets for a tight seal Try the dollar-bill test: close it on a bill and pull â it should resist | Every 6 months | 1 ¡ Beginner | 5 min | A worn gasket lets warm air in continuously, and the compressor runs nonstop trying to compensate |
Replace the water filter Swap per the manufacturer's indicator or schedule | Every 6 months or per indicator light | 1 ¡ Beginner | 5 min | An old filter reduces water and ice flow and can affect taste or odor |
Check that the fridge is level Adjust the leveling feet so doors close and stay shut on their own | Annually, or if doors don't stay shut | 1 ¡ Beginner | 10 min | An unlevel fridge can cause doors to swing open or shut unevenly, straining the gasket seal |
Troubleshooting
Symptom
Likely cause
Action
Who
Fridge runs constantly, compressor never cycles off
Dirty coils or a failing door seal
Vacuum the coils first and test the door gaskets
DIY ok
Warm spots inside despite the thermostat setting
Blocked interior airflow vents, or dirty coils reducing overall cooling capacity
Clean the coils and check that interior vents aren't blocked by food
DIY ok
Water pooling under the fridge
A clogged or misaligned condensate drain/pan
Clean and reseat the drain pan; clear the drain tube if accessible
DIY ok
Loud buzzing or clicking and the unit won't cool
A failing compressor or start relay
This needs a professional appliance repair diagnosis

Older refrigerators and many compact/mini fridges expose their condenser coils on the back panel instead of behind a front grille. They’re easy to forget about specifically because they’re out of sight behind the unit.
Maintenance tasks
| Task | Cadence | Skill | Time | Consequence if skipped |
|---|---|---|---|---|
Pull the fridge out and vacuum the rear coils Unplug first, then use sliders or a dolly to move it out for access | Every 6â12 months | 2 ¡ Confident | 20â30 min including moving the unit | Exposed rear coils collect dust just as fast as any other type, but are easier to miss since they're out of sight |
Clean the floor and wall area behind the fridge Sweep and wipe down while access is open | Every 6â12 months | 1 ¡ Beginner | 10 min | Dust and debris behind an appliance is a commonly overlooked pest attractant |
Check the rear coil fan for dust buildup Wipe or brush the fan blade if the model has one | Annually | 2 ¡ Confident | 10 min | A caked fan blade moves less air across the coils, undermining the whole point of cleaning them |
Inspect the power cord and rear panel Check for pinching, fraying, or damage while access is open | Annually | 1 ¡ Beginner | 5 min | A pinched or frayed cord behind an appliance can go unnoticed for years |
Check door gaskets for a tight seal Same dollar-bill test as any refrigerator | Every 6 months | 1 ¡ Beginner | 5 min | A worn gasket forces the compressor to run constantly trying to compensate |

Hard to pull the fridge out without scratching the floor
No furniture sliders or dolly used

Coils coated in a thick dust blanket not cleaned in years

A shop vac plus a coil brush works better than a standard vacuum attachment for heavy buildup

Fridge runs constantly
Same as any type â dirty coils or a bad door seal

Built-in and many cabinet-depth counter-depth models vent from the front only, with coils tucked into a tight enclosure for a flush cabinet look. Access is often limited to a front grille, and dense installations can make thorough cleaning genuinely difficult â some manufacturers explicitly recommend leaving deeper cleaning to a technician.
Maintenance tasks
| Task | Cadence | Skill | Time | Consequence if skipped |
|---|---|---|---|---|
Vacuum the front grille/vent area Light, more frequent cleaning since airflow is more restricted to begin with | Every 3â6 months | 1 ¡ Beginner | 10 min | Front-vented units have less airflow margin, so buildup affects cooling faster than on a standard freestanding model |
Check manufacturer guidance before deeper cleaning Confirm the panel removal order before attempting full coil access | Before deep cleaning | 1 ¡ Beginner | Research task | Some built-in models require removing panels in a specific order, and forcing it risks damaging trim or seals |
Schedule professional coil cleaning if needed When grille access alone isn't enough | Every 1â2 years | 3 ¡ Advanced | Professional service | Buildup you can't reach yourself doesn't stop accumulating â it just becomes a bigger job later |
Check door alignment and gasket seal Built-in doors often carry more elaborate trim and weight | Every 6 months | 1 ¡ Beginner | 5 min | Misalignment strains the seal more than it would on a standard model |
Keep cabinet-side ventilation gaps clear Confirm nothing blocks the manufacturer-specified clearance | Ongoing | 1 ¡ Beginner | N/A | Built-in installations rely on these gaps for airflow, and stored items or trim changes can block them |

Who
Front panel runs hot to the touch
Normal for some front-vented designs, but excessive heat can mean restricted airflow
Confirm nothing is blocking the top or side ventilation gaps per the manual

Cooling has gradually declined over a year or more
Coil buildup inaccessible from the front grille alone
Schedule a professional cleaning rather than attempting to disassemble cabinet panels

A trim panel doesn't sit flush after DIY cleaning
Panels reinstalled out of order or a clip not reseated
Consult the manual for the specific reassembly order
