The transformer steps down 120V line voltage to the 24V AC signal that powers the entire low-voltage control circuit — including the thermostat, gas valve, control board, and safety switches. When this transformer fails, the furnace goes completely silent: the thermostat gets no response, no call for heat is processed, and nothing in the system energizes. A failed transformer is often misdiagnosed as a bad control board, so always test here first with a multimeter.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Input: 120V AC | Output: 24V AC | 40VA rating | Factory OEM part number HT01BC116 | Direct plug-in or wire-lead termination to match OEM configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier transformer engineered to exact 40VA output tolerances for the PG9MAB036060AASA.
