To check a BLDC motor's wire composition, identify the three main phase wires typically color-coded (e.g., red, yellow, blue). Use a multimeter to test for continuity and ensure equal resistance between each pair. Inspect for insulation quality and proper connections to prevent short circuits and ensure optimal performance. #airconditioning #hvac #heating #hvaclife #airconditioner #hvacservice #ac #cooling #hvactechnician #hvactech #heatingandcooling #hvacrepair #hvacinstall #refrigeration #hvac
