The transformer steps down incoming 120V line voltage to the 24V signal required by your thermostat, control board, gas valve, and all low-voltage control circuit components. When this part fails, the entire control circuit goes dead — your thermostat won't respond, the furnace won't ignite, and nothing happens when you call for heat. It is one of the first components to check whenever a furnace shows absolutely no signs of life.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V primary input | 24V secondary output | 40VA rated | Factory OEM replacement for part number HT01BC116\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier part engineered to exact voltage and VA tolerances for the PG9MAA036040ABKA.
