Temperature Changes
Record fresh-food and freezer temperatures plus the time the change began.
True Guide
True Residential refrigeration brings commercial build to the home kitchen, and it performs best with regular condenser cleaning, firmly sealing gaskets, and prompt, symptom-based diagnosis when a unit drifts off temperature.
True built its name in commercial refrigeration, and its residential line carries that heritage: heavy build, forced-air cooling, and precise temperature control across refrigerator columns, undercounter units, and wine storage. The build is robust, but it still depends on shedding heat through a clean condenser and sealing the cabinet with good gaskets.
True refrigeration is diagnosed by symptom rather than a set of consumer numeric codes, so a technician reads the unit's behavior and tests components directly.
Clean the condenser on a regular schedule, because True's strong forced-air cooling still cannot overcome a clogged coil. Check the heavy-duty gaskets so the doors seal fully, and keep the unit properly ventilated. On wine and dual-temperature units, watch for one zone drifting while the other holds, which points to a component in that zone.
When a True unit runs warm or will not hold its setpoint, the usual causes are the condenser, a fan motor, the defrost system, a thermistor, or a control fault. Each is serviceable, and we diagnose the exact cause before quoting a repair.
Record fresh-food and freezer temperatures plus the time the change began.
Photograph the exact location and check whether the door closes without interference.
Describe when the sound starts and whether airflow or cooling has also changed.
Note filter history, supply flow, ice output, and the first visible point of moisture.
True residential refrigeration does not present consumer numeric fault codes, so diagnosis reads the unit's behavior and tests the fans, sensors, and sealed system directly.
Diagnostic and travel fees, if applicable, are confirmed before the appointment and before repair approval.
