OEM Carrier 40VA Control Transformer HT01BC116 for Model PG8MAA024070AAJA

This OEM control transformer is the factory-specified replacement for the Carrier PG8MAA024070AAJA gas furnace. The transformer steps down line voltage from 120V to 24V to power the low-voltage control circuit — including the thermostat, gas valve, inducer, and control board. When it fails, the entire control system goes dark: the thermostat loses power, the furnace will not respond to a heat call, and in some cases the system will blow a 3A control fuse repeatedly if a secondary short is present.

  • Specs: Input 120V AC | Output 24V AC | 40VA rated | OEM part number HT01BC116 | Factory-matched windings and mounting footprint for drop-in replacement
  • OEM vs Generic: This is a genuine Carrier OEM transformer wound to exact factory VA and voltage tolerances. Generic transformers often run under-rated on VA capacity, causing thermal overload, nuisance fuse failures, and premature control board damage.
  • Install Difficulty: 2/5 — Disconnect power at the breaker and verify zero voltage before handling. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Label all wires before disconnecting the old transformer. Check and replace the 3A control fuse if blown.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier PG8MAA024070AAJA 80% AFUE gas furnace. Always verify your existing transformer's input/output voltage and VA rating against your unit's data plate before ordering. Have a question about fitment? Our HVAC parts specialists verify compatibility before you buy — reach out before placing your order.

Frequently Asked Questions

Does this Transformer fit my Carrier PG8MAA024070AAJA?
Yes. This is the factory-specified OEM transformer for the Carrier PG8MAA024070AAJA. 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 PG8MAA024070AAJA?
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?
