Why this happens
What we look for first.
- Evaporator fan motor stalled or seized. The evaporator fan sits behind the back panel in the freezer or column and pulls cold air off the evaporator coil and pushes it into the compartments. When the motor bearing dries out or the blade ices into the shroud, airflow stops and the fresh-food side warms while the coil stays cold. You will often hear a faint clicking or grinding from the back wall, or dead silence where a soft hum should be. We pull the back panel, check the motor for play and resistance, and swap the fan if it is dead. This is one of the cheaper not-cooling repairs.
- Condenser fan or dirty condenser coil. On these built-in columns the condenser fan and coil live in the lower compressor bay or up top depending on the model. When the fan motor fails or the coil packs with dust and pet hair, the compressor cannot reject heat and head pressure climbs until cooling falls off. The fridge runs constantly and the bay gets hot. We clean the coil, verify the condenser fan spins freely and pulls correct amperage, and replace the motor if it is binding.
