True FAQ
Where should I start with True error codes?
Start with the exact True model and displayed code or alarm, then open the closest guide on this page. Match the symptom, recent service history, and any secondary codes before resetting the equipment or ordering parts.
Do True fault codes always mean a bad control board?
No. Many True codes point to airflow, water flow, sensors, wiring, power quality, filters, switches, or operating conditions. Check the simple causes in the guide before replacing an expensive board.
When should I stop troubleshooting a True fault myself?
True refrigeration faults can involve high-voltage controls, refrigerant, water valves, defrost heaters, or food-safety temperature risk. Stop and use the repair checklist or compare service options when the guide points to gas, refrigerant, line voltage, sealed-system work, food-safety temperatures, or repeated faults after a reset.
