It converts 120V line voltage to the 24V AC signal that powers every low-voltage component in the system — the thermostat, gas valve, inducer relay, and control board. When this transformer fails, the furnace goes completely dark: the thermostat loses signal, the board stops responding, and the heating cycle never initiates. If your furnace shows no response to a thermostat call and 24V is absent between the R and C terminals on the board, this transformer is the most likely culprit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA capacity | 120V primary input | 24V secondary output | 60 Hz | Single phase | Wire lead connection type | Compact foot-mount design (approx. 3″ L × 2.1″ W × 2″ H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier transformer shipped in a factory-authorized parts box. Generic transformers frequently run outside VA tolerance, causing nuisance board shutdowns, intermittent thermostat dropouts, and premature low-voltage component failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Power down and lock out the furnace at the breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 0V before touching wires). Photograph all wiring connections before disconnecting. The transformer mounts to the blower deck or control panel with two screws; wire leads connect to push-on terminals.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty.

Part number HT01BC116 has been factory-superseded by updated OEM part HT680054 — our listing ships the current production unit, which is a direct drop-in with no modification required. Also cross-references to HT01BC115, HT01BB126, HT01CT120, HT01BC120, and several other legacy Carrier\/Bryant\/Payne transformer part numbers. Verify your unit's control board calls for a 40VA 120V\/24V transformer before ordering.\u003c\/p\u003e","brand":"Carrier","offers":[{"title":"OEM","offer_id":62643227296115,"sku":"CARRIE-PG8DAA060135ADJA-TRANSFORMER-HT01BC116","price":51.95,"currency_code":"USD","in_stock":true},{"title":"Generic","offer_id":62643227328883,"sku":"CARRIE-PG8DAA060135ADJA-TRANSFORMER-HT01BC116-GEN","price":45.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-transformer-HT01BC116_050851b2-454f-40fe-bbd4-4c4291535fb4.jpg?v=1775031755","url":"https:\/\/nationalhvacparts.com\/products\/carrier-pg8daa060135adja-transformer-h2usbz","provider":"National HVAC Parts","version":"1.0","type":"link"}
