OEM Carrier Control Transformer 120V–24V 40VA for Model PG9MTAV36075ABSS

This OEM Carrier control transformer (part# HT01BC117) is the factory-specified replacement for the PG9MTAV36075ABSS gas furnace. The transformer steps down line voltage from 120V AC to 24V AC to power the furnace's low-voltage control circuit — including the thermostat, gas valve, inducer relay, and control board. When this component fails, the entire control circuit goes dead: the thermostat shows no response, the furnace does not attempt ignition, and nothing operates. It is often one of the first components to inspect when a furnace appears completely unresponsive.

  • Specs: Input 120V AC | Output 24V AC | 40VA rated | Factory OEM part number HT01BC117 | Direct drop-in replacement with no modifications required
  • OEM vs Generic: This is a genuine OEM Carrier transformer wound to exact VA and voltage tolerances. Generic transformers can run under-rated VA, causing voltage sag under load that trips the control board or damages the gas valve solenoid over time.
  • Install Difficulty: 2/5 — Disconnect power to the furnace before beginning. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter (to confirm 24V output after install). Photograph or label all low-voltage wiring before disconnecting. Typical replacement time is 20–30 minutes.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships the same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for the Carrier PG9MTAV36075ABSS gas furnace. Always verify your unit's data plate voltage and VA rating before ordering to ensure a correct match. Need help confirming fitment? Our HVAC parts specialists verify compatibility before you buy — contact us today and get your furnace back online fast.

Frequently Asked Questions

Does this Transformer fit my Carrier PG9MTAV36075ABSS?
Yes. This is the factory-specified OEM transformer for the Carrier PG9MTAV36075ABSS. 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 PG9MTAV36075ABSS?
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?
