I was actually surprised this auto transformer still worked and powered the induced draft motor. I think we should replace it anyway as a precaution. For my US friends, these Carriers are 575V primary in Canada and some components are 460V. So they use an auto transformer in this case to step down the voltage. This WiringPro kit I picked up from Master a year or so ago has been invaluable for electrical repairs. #hvac #hvacr #hvacservice #hvacservicetip #hvacaf #hvaclife #carrierrooftop #noheatc
