• Hassle-Free Installation Boasting a plug-and-play design, this board directly connects to your original wiring harness. Cut off all power supply prior to installation. If you lack professional experience, please hire a licensed HVAC technician for safe fitting.
• WARNINGOnly copper wires are permitted for PCBDM133S installation; aluminum wires are forbidden. Aluminum oxidizes rapidly to form insulating film, creates galvanic corrosion with copper terminals, and loosens connections after repeated heating/cooling cycles, leading to overheating, sparking and board burnout.
• MaintenanceDefrost control board needs little upkeep, but routine HVAC inspections are suggested.Visually inspect the board for damage, corrosion or burnt parts, secure all wiring connections free of corrosion, and clear surrounding dust/debris for efficient heat dissipation.
