OEM Carrier Transformer 40VA 120V/24V for Model PG9MAB048060ABSA

This is the OEM factory-specified control transformer for the Carrier PG9MAB048060ABSA gas furnace, identified by part number HT01BC116. The transformer steps down 120V line voltage to 24V AC, powering the entire low-voltage control circuit — including the thermostat, gas valve, inducer relay, and control board. When the transformer fails, the system goes completely unresponsive: the thermostat goes dark, the furnace won't call for heat, and no error codes are generated because the board itself has lost power. Replacing this component is often the fastest fix for an otherwise inexplicably dead furnace.

  • Specs: 120V primary | 24V secondary | 40VA rated | Direct OEM replacement for part number HT01BC116 | Plug-and-play wiring harness connections
  • OEM vs Generic: The OEM HT01BC116 transformer is wound and insulated to Carrier's exact VA and voltage tolerances. Off-brand transformers frequently deliver under-voltage on the secondary side, causing erratic board behavior, nuisance lockouts, and premature control board failure — costing far more than the part itself.
  • Install difficulty: 2/5 — Shut off power at the breaker and disconnect the thermostat wires before starting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output after install). Photograph existing wiring connections before removal.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Engineered as a direct OEM drop-in for the Carrier PG9MAB048060ABSA 80% AFUE gas furnace. Always verify your existing transformer's VA rating and part number on the unit's data plate or wiring diagram before ordering. Have questions about fitment?

Frequently Asked Questions

Does this Transformer fit my Carrier PG9MAB048060ABSA?
Yes. This is the factory-specified OEM transformer for the Carrier PG9MAB048060ABSA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the transformer on my Carrier PG9MAB048060ABSA?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Photo wiring connections. Step 3: Disconnect wires from old transformer. Step 4: Remove mounting hardware. Step 5: Install new transformer, reconnect wires matching voltage ratings. Step 6: Verify 24V output with multimeter.
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?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. 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.
How fast does National HVAC Parts ship?
