Originally sold under part number \u003cstrong\u003eHT01BC116\u003c\/strong\u003e, this component has been updated by Carrier to the current OEM part number \u003cstrong\u003eHT680054\u003c\/strong\u003e — a direct drop-in factory replacement supplied in a Carrier-authorized parts box. The transformer converts 120V line voltage down to 24V AC to power all low-voltage control components including the thermostat, gas valve, and control board. When it fails, the result is a completely unresponsive system: the thermostat goes dark, the furnace will not ignite, and no low-voltage signals reach any component downstream.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rating | 120V primary \/ 24V secondary | 50\/60 Hz | Single-phase | Foot-mount | Compact 3\" × 2-2\/16\" × 2\" form factor | Wire lead connections\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM unit shipped in a factory-authorized box, matched precisely to the PG8MAA060155ACJA's low-voltage circuit load. Generic transformers may be rated at ±10% VA tolerance, risking undervoltage to the gas valve or control board and causing nuisance lockouts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off power at the breaker and confirm 0V with a multimeter before touching wiring.
