OEM Carrier 40VA Control Transformer HT01AW229 for Model CH13NA06000GACAA

This OEM replacement transformer (part number HT01AW229) is the factory-specified control circuit transformer for the Carrier CH13NA06000GACAA split-system air conditioner. The transformer steps down 120V line voltage to the 24V AC signal that powers your thermostat, contactor coil, and all low-voltage control components. When this transformer fails, the entire control circuit goes dead — your thermostat will go blank, the system won't respond to calls for cooling, and no safety faults will even register on the board.

• Specs: 40VA rated | 120V primary → 24V secondary | Single-phase | Factory-matched output tolerance for stable low-voltage control signal
• OEM vs Generic: The OEM HT01AW229 transformer is wound to Carrier's exact VA and voltage specifications. Generic transformers may sag under load, producing undervoltage that causes erratic contactor chatter, nuisance thermostat lockouts, and premature control board failure.
• Install difficulty: 2/5 — Shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter (to confirm 24V output after install). Label all wiring connections before removal. Installation typically takes 20–30 minutes.
• Warranty: 1-year OEM factory warranty against defects. Orders placed by 3PM ship same business day from our climate-controlled warehouse.

Compatibility: Engineered specifically for the Carrier CH13NA06000GACAA condenser/air handler system. Always verify your existing transformer's VA rating and voltage markings on the data plate before ordering to ensure a direct drop-in fit. Have questions about fitment?
