OEM Carrier Control Transformer 40VA 208/230V to 24V for Model PY2PNB060130AB

This OEM Carrier transformer (part #HT01BD209) is the factory-specified control transformer for the Carrier PY2PNB060130AB packaged unit. Its job is fundamental: step down high-voltage line power (208/230V) to the safe 24V AC signal that energizes every low-voltage control circuit in the system — your thermostat, contactor coil, control board, and zone valves. When the transformer fails, the entire control circuit goes dark. No thermostat response, no call-for-cooling or call-for-heat acknowledgment, and no system operation whatsoever — even if every other component is in perfect working order.

• Specs: 208/230V Primary | 24V Secondary | 40VA Power Rating | 50/60Hz | OEM Part #HT01BD209 | Weight: ~1.3 lbs
• OEM vs Generic: OEM transformers are wound and tested to Carrier's exact VA rating and insulation class. Undersized or off-spec generic transformers can overheat under peak demand, trip the built-in thermal fuse, and fail again within weeks — leaving you back at square one.
• Install difficulty: 2/5 — Shut off power at the disconnect and breaker before starting. Tools needed: flathead and Phillips screwdrivers, wire nuts or spade terminals, multimeter (to confirm 24V output after install). Label all wires before disconnecting. Verify primary voltage at your unit's data plate matches the transformer's input rating.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse when ordered before cutoff.
