When a refrigerator quits cooling, it's not just a maintenance inconvenience — it's a race against spoiling groceries. Below are the five faults that show up again and again on our service calls, arranged from simplest DIY fix to full technician territory.
1. Dust-Caked Condenser Coils
Tucked behind or beneath the cabinet, the condenser coils are where the refrigerant sheds the heat it pulled out of your food compartment. Once they're buried under a felt of dust and pet fur, that heat has nowhere to go — the compressor grinds away nonstop and the interior temperature creeps upward. Houston's humidity makes this worse, since damp dust cakes onto the coil fins more stubbornly than dry dust does.
Fix: Unplug the unit, slide it away from the wall, and run a vacuum brush attachment over the coils. Plan on doing this twice a year here, rather than the usual once-a-year advice, given the humid air.
2. A Stalled Evaporator Fan Motor
This small fan pushes chilled air out of the freezer and into the fresh-food section. When it quits, the freezer often stays plenty cold while the refrigerator above or beside it slowly warms — and you'll usually hear a rattling or grinding sound from the freezer compartment before it fails outright.
Fix: Replacing this motor means pulling the rear freezer panel, so it's a technician job rather than a weekend project.
3. Ice Choking the Evaporator Coil
When the defrost heater or its thermostat stops cycling properly, frost keeps building on the evaporator instead of melting off on schedule, and eventually it blocks airflow completely. The giveaway: a warm fridge paired with a freezer that's grown a noticeably thick ice shell.
4. A Gasket That's Lost Its Seal
Once the rubber door gasket cracks or goes slack, warm room air seeps in continuously, and the compressor never gets a break trying to chase a temperature it can't reach.
Test: Shut the door on a dollar bill. If it pulls free with little resistance, the seal has failed and needs replacing.
5. A Dying Compressor
The compressor drives the entire cooling cycle. Listen for a repeated clicking every few minutes as the start relay tries and fails to kick it over — or, in later stages, dead silence where a hum should be.
