GE GTS18GTHWW 17.5 cu ft Top Freezer Refrigerator White MECH-COILS Error Fix: Condenser Coils Dirty — Runs Constantly

The refrigerator runs almost continuously, the exterior feels very hot, and it struggles to maintain temperature — the condenser coils (located at the rear bottom or underneath the refrigerator) are covered with dust, pet hair, and debris; the condenser dissipates heat from the refrigerant; when coils are dirty, the compressor works overtime; clean the coils every 6-12 months using a coil brush or vacuum with a brush attachment; pull the refrigerator away from the wall for access
