OEM Carrier Control Transformer 40VA 208/240V to 24V for Model PY2PPB060130NB

This OEM control transformer (part number HT01BD209) is the factory-specified replacement for the Carrier PY2PPB060130NB packaged unit. The transformer steps down high-voltage line power (208/240V) to the 24V required by the system's low-voltage control circuit — powering the thermostat, control board, and all 24V safety and relay components. When this part fails, the entire control circuit goes dead: the thermostat loses power, the system will not respond to any command, or you may hear faint buzzing from the transformer housing while nothing else operates.

• Specs: 40VA output | 208/240V primary | 24V secondary | 50/60 Hz | OEM part number HT01BD209 | Replaces HT01BD207, HT01CN232, 9076-00
• OEM vs Generic: This is a genuine Carrier OEM transformer, wound and rated to exact factory tolerances. Generic transformers may underperform under sustained load, causing nuisance control-circuit dropouts, board resets, or premature contactor wear from undervoltage.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter (to verify 24V output after install). Label all wires before disconnecting. Confirm primary tap selection (208V vs 240V) matches your supply voltage.
• Warranty: 1-year OEM manufacturer warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PY2PPB060130NB. Verify your unit's supply voltage (208V or 240V) against the transformer's primary tap before installation — mismatched voltage selection will damage the part. Questions about fitment?
