True built its name on commercial refrigeration and brought that engineering home, and its color-customizable columns and beverage units have become a signature in Highlands Ranch's design-forward kitchens. True refrigeration is forced-air and robust, and it rewards a technician who treats it like the commercial equipment it descends from: check the airflow, the fans, and the condenser before anything else.
Models We Service
- Refrigerator and freezer columns in the 24 and larger widths
- Undercounter refrigerators, freezers, and drawers
- Wine columns and dual-zone wine cabinets
- Beverage and glass-door refrigerators

Error and Fault Codes
True Residential units report through their controller and behavior rather than a numbered front-panel fault code. We read the controller status and test the refrigeration, fan, and defrost circuits directly. The table shows how we approach the most common complaints.
| Symptom | Likely Cause | What We Do |
|---|---|---|
| Cabinet running warm | Evaporator fan or airflow blockage | Test fan, clear airflow, check defrost |
| Compressor runs constantly | Fouled condenser or low charge | Clean condenser, leak-test sealed system |
| Frost buildup | Defrost heater or terminator fault | Ohm-test defrost components, replace part |
| Wine zone drift | Thermistor or damper fault | Verify with probe, replace sensor or free damper |
| Loud operation | Worn fan bearing | Replace fan motor or bearing |
Common Problems We Fix
Because True moves a lot of air, its evaporator and condenser fans are the parts most likely to announce themselves, first as noise, then as a warm cabinet when a bearing finally seizes. Condensers fouled with dust make the compressor run long and hot, which is worth catching early. On wine and beverage units, thermistor drift and stuck dampers cause the temperature complaints. Defrost heaters and terminators fail like any forced-air refrigeration. We diagnose by measured value and keep the commercial-grade cooling True is known for running the way it was built to.
