OEM Carrier Control Transformer 40VA 208/230V to 24V for Model PY2PPB060090NB

This genuine OEM Carrier control transformer (part #HT01BD209) is the factory-specified replacement for the Carrier PY2PPB060090NB packaged unit. The transformer steps down 208/230V line voltage to the 24V signal required by your thermostat, control board, gas valve, and all low-voltage control circuits. When the transformer fails, the entire control circuit goes dead — the thermostat goes blank, the system won't respond to calls for heating or cooling, and no error codes can even be generated. Replacing a failed transformer is the fastest way to restore full system control.

• Specs: 40VA output | 208/230V primary input | 24V secondary output | 50/60 Hz | Class 2 control transformer | Replaces HT01BD207, HT01CN232, 9076-00
• OEM vs Generic: OEM transformers are wound to exact VA and voltage tolerances required by Carrier's control board. Undersized or off-tolerance aftermarket units can cause nuisance tripping, board brownouts, and premature contactor coil failure.
• Install difficulty: 2/5 — Disconnect power at the breaker before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter to verify 24V output after install. Label wires before removing old unit. Always verify output voltage before buttoning up the panel.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse — order by 3 PM local time.

Compatibility: Designed for the Carrier PY2PPB060090NB packaged unit. Also replaces legacy part numbers HT01BD207, HT01CN232, and 9076-00 across multiple Carrier, Bryant, and Payne platforms. Always verify primary voltage (208V or 230V) on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.
