OEM Carrier 24V Control Transformer HT01BC116 for Model PG8MAA036110AAJA

This OEM replacement control transformer is the factory-specified part for the Carrier PG8MAA036110AAJA packaged gas/electric unit. The transformer steps down 120V line voltage to the 24V AC signal that powers the control board, thermostat circuit, gas valve, and all low-voltage control components. When this part fails, the entire control circuit goes dead — the thermostat loses power, the system will not respond to any heating or cooling calls, and you may find a blown fuse on the control board caused by a shorted secondary winding.

  • Specs: 120V primary | 24V secondary | 40VA rating | OEM part number HT01BC116 | Factory drop-in fit for Carrier PG8MAA036110AAJA
  • OEM vs Generic: This is a genuine OEM Carrier transformer wound to exact VA and voltage tolerances. Generic transformers often carry ±10% voltage variance that can cause erratic thermostat behavior, nuisance lockouts, or repeated fuse failures under load.
  • Install difficulty: 2/5 — Always disconnect power at the breaker and verify zero voltage before handling. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter to confirm secondary voltage after installation. Label or photograph all wiring connections before removal.
  • Warranty: 1-year OEM factory warranty against defects. Orders ship same business day from our warehouse when placed before cutoff.

Compatibility: Engineered specifically for the Carrier PG8MAA036110AAJA packaged gas/electric unit. Verify your unit's data plate shows OEM part number HT01BC116 before ordering. If you have any questions about fitment, our HVAC parts specialists can confirm compatibility before you buy — same-day shipping available on all in-stock orders.

Frequently Asked Questions

Does this Transformer fit my Carrier PG8MAA036110AAJA?
Yes. This is the factory-specified OEM transformer for the Carrier PG8MAA036110AAJA. 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 PG8MAA036110AAJA?
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?
