Condenser and Ventilation
True's forced-air cooling depends on a clean condenser and the ventilation clearances in the installation manual. A dusty coil or a unit crammed into tight cabinetry runs warm because it cannot shed heat, and this is the most common cause of a True unit that has drifted warm. Cleaning the condenser and clearing airflow often restores cooling.
| Symptom | Likely Cause | Fix |
|---|---|---|
| Gradual warm drift | Dirty condenser or venting | Clean coil, clear airflow |
| Warm, runs constantly | Failed fan | Test and replace fan |
| Ices up then warms | Defrost fault | Replace defrost part |
| Warm after all checks | Sealed system or control | Diagnose system and control |
Fans and Airflow
If the unit runs constantly but stays warm, a failed condenser fan or evaporator fan is a likely cause. The condenser fan cools the coil; the evaporator fan circulates cold air inside. When either stops, cooling suffers even though the compressor is running. Testing and replacing the failed fan resolves it.
Defrost and Coil
A frozen evaporator coil from a defrost fault blocks airflow and warms the compartment. On a unit that ices up and then warms, the defrost system, the heater, thermostat or control, is the suspect. Clearing the ice and replacing the failed part restores normal operation.
Sealed System and Controls
When condenser, fans and defrost all check out, a sealed-system leak or a control fault may be the cause. Sealed-system work requires appropriately qualified handling and is worthwhile on a unit of this quality. Because True reports by behavior rather than a code, a technician tests each part in turn to confirm the fault before repairing.

Frequently Asked Questions
Why Is My True Residential Unit Not Cooling?
Usually a dirty condenser or restricted ventilation, or a failed condenser or evaporator fan. Cleaning the coil and clearing airflow resolves many cases. A unit that runs constantly and stays warm needs the fans, defrost or sealed system checked.
Does True Residential Use Error Codes?
No. True does not publish a broad numeric fault-code set, so a warm unit is diagnosed by symptom and Reddingnent testing, checking the condenser, fans, defrost and sealed system to find the cause.
Is a Warm True Unit Worth Repairing?
Usually yes. Most causes, a dirty condenser, a fan, or a defrost part, are modest repairs. Even a sealed-system repair is worthwhile on a well-built unit of this quality against the cost of replacement.
