The control transformer steps line voltage down from 115\/208\/230V primary to a safe 24V secondary, powering the entire low-voltage control circuit — thermostat, contactor coil, control board, and all safety switches. When this transformer fails, \u003cem\u003enothing\u003c\/em\u003e in the system responds: the thermostat goes blank, the contactor won't pull in, and the unit will not start at all. If you're measuring 0V at the R and C terminals of your control board, a failed transformer is the most common cause.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 60VA capacity | Primary voltage: 115 \/ 208 \/ 230V AC | Secondary voltage: 24V AC | Foot-mounted configuration | Factory-matched to Carrier PH13NR03600GACAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM transformers are wound to exact VA and voltage tolerances.
