Why does the inside of my fridge feel warm?

When the interior storage compartments of your residential refrigerator feel warm despite the appliance running continuously, several common airflow, mechanical, or environmental failures are typically at fault. The most frequent cause is heavy dust and pet hair accumulation blocking the exterior condenser coils beneath or behind the unit, which insulates the coils and prevents proper heat dissipation. Other common culprits include frosted-over evaporator coils hidden behind the freezer back panel due to a broken defrost heater, a failed evaporator fan motor that stops circulating chilled air, or worn-out rubber door gaskets letting warm room air seep inside continuously. You can troubleshoot by inspecting condenser coils and door seals. You can verify that your troubleshooting is successful when cleaning coils, defrosting iced evaporator coils, or replacing faulty fan motors restores stable, cold storage temperatures.
