The transformer steps down 120V line voltage to the 24V signal required to power your thermostat, control board, contactor coil, and all low-voltage safety controls. When this part fails, the entire control circuit goes dark — the thermostat loses power, nothing responds, and the system will not heat or cool regardless of settings. If you have confirmed 120V supply voltage at the unit but zero 24V output, this transformer is almost certainly the cause.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 40VA rated | 120V primary \/ 24V secondary | OEM part number HT01BD209 | Factory-matched output tolerance for stable low-voltage control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound and potted to Payne's exact VA and voltage specifications.
