OEM Carrier 40VA Control Transformer for Model PG9MAB048060AASA

This OEM step-down transformer (part# HT01BC116) is the factory-specified replacement for the Carrier PG9MAB048060AASA 80% AFUE packaged gas furnace. The transformer steps down 120V line voltage to 24V AC, powering the entire low-voltage control circuit — including the thermostat, control board, gas valve, and all safety switches. When it fails, the system goes completely silent: no thermostat response, no inducer start, nothing. A failed transformer is often misdiagnosed as a bad control board, making this an essential first diagnostic check.

  • Specs: Input: 120V AC | Output: 24V AC | Rating: 40VA | OEM Part Number: HT01BC116 | Factory-matched for PG9MAB048060AASA
  • OEM vs Generic: This is a genuine OEM Carrier transformer, wound and rated to exact factory specifications. Generic transformers may share the voltage rating but often lack proper VA capacity, causing nuisance brownouts, tripped breakers, or premature control board damage under full system load.
  • Install difficulty: 2/5 — Shut off power to the furnace at the disconnect before touching any wiring. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Label or photograph all wire connections before removal. Transformer mounts to the vestibule panel with a single screw bracket on most applications.
  • Warranty: 1-year OEM factory warranty against defects. Orders ship the same business day when placed before cutoff.

Compatibility: Engineered for the Carrier PG9MAB048060AASA packaged gas furnace. Always verify your unit's data plate voltage and VA requirements before ordering. If you are unsure of fitment, our technical team is available to confirm compatibility before you purchase. In stock and ready to ship today.

Frequently Asked Questions

Does this Transformer fit my Carrier PG9MAB048060AASA?
Yes. This is the factory-specified OEM transformer for the Carrier PG9MAB048060AASA. 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 PG9MAB048060AASA?
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.
