A refrigerator that keeps running but slowly warms is one of the calls we take most across Vinings and the Atlanta metro. The compressor may still hum while the compartment climbs, which usually points to airflow, the defrost circuit, or the sealed system rather than a full power loss.
Notes by Brand
The same symptom can have different causes depending on the brand. Here is how we approach refrigerator not cooling across the roster.
Sub-Zero
A warm fresh-food side over a cold freezer usually means that side's sealed system, its evaporator fan, or a defrost fault. The service light may also be flagging a clogged condenser.
Wolf
Wolf does not build standalone refrigeration, so a cooling call here means a paired Sub-Zero unit, which we diagnose directly on the affected side.
Bosch
We check the evaporator fan, the air damper, and the defrost circuit first. Counter-depth Bosch units are sensitive to blocked vents when they are overpacked.
Miele
MasterCool units may post a fault indication. We test the fan, the sensor, and the sealed system and confirm airflow across the compartments.
Viking
Clean the condenser first, then test the evaporator fan and the sealed system. Near the water, condensers clog faster from salt and dust.
Liebherr
An E1 sensor fault or a temperature alarm often rides along with a warm section. We measure the sensor and verify airflow.
Kitchenaid
We test the evaporator fan, the damper, and the defrost circuit, then the compressor and start components if airflow checks out.

Indications and What We Check
| Symptom | Likely Cause | What We Check |
|---|---|---|
| Warm section | An airflow, defrost, or sealed-system fault | Test the fan, the defrost circuit, and the sealed system |
| Compressor runs, no cooling | A sealed-system or start-component fault | Test the compressor, start relay, and refrigerant charge |
| Ice on the evaporator | A defrost heater or sensor fault | Test the defrost heater, sensor, and control |
