OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH10JA04200GAGAA

This is the genuine OEM factory-specified control transformer for the Carrier PH10JA04200GAGAA packaged heat pump system. The transformer steps down line voltage (115, 208, or 230V primary) to the 24V AC signal that powers the entire low-voltage control circuit — including the thermostat, contactors, relays, and control board. When this transformer fails, nothing in the system responds: the thermostat goes blank, the unit won't call for heating or cooling, and a multimeter at the secondary terminals will read 0V instead of 24V.

  • Specs: 60 VA power rating | 115/208/230V primary input | 24V AC secondary output | 50/60 Hz | Foot-mounted configuration | OEM Part Number HT01AW229
  • OEM vs Generic: This factory-authorized part is wound to exact Carrier tolerances, ensuring stable 24V output under full control-circuit load. Generic transformers often underperform at 60VA draw, causing intermittent resets, nuisance lockouts, and premature board failures.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker panel before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter. Label all low-voltage wires before disconnecting. Verify 0V at primary terminals before touching any leads.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PH10JA04200GAGAA. Also cross-references to HT01AW229A. Confirm your unit's primary voltage (115V, 208V, or 230V) matches your supply voltage before ordering. Not sure? Our fitment team verifies compatibility before you buy — order with confidence and get your system back online today.

My thermostat has no power. What failed?
Thermostat with no display = failed 24V transformer (or blown control board fuse). Check the 3A/5A fuse on the control board first ($1–$5 fix). If fuse is good but no 24V output from transformer, replace transformer.
Is this transformer compatible with Bryant or Payne too?

The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier transformer?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
