Prior to performing any diagnostic testing or taking electrical measurements on residential or commercial equipment, always lock out / tag out (LOTO) power sources and shut off fuel or water supplies. Wear rated personal protective equipment (insulated gloves, eye protection) and use a calibrated CAT III/CAT IV digital multimeter.
If fault symptoms persist after executing our pinout checks and component resistance tests, consult a factory-certified technician or licensed HVAC/appliance specialist.
