OEM Carrier Control Transformer 40VA 120V/24V for Model C48A206061 — HT01BD236

This OEM control transformer (part number HT01BD236) is the factory-specified replacement for the Carrier C48A206061 packaged unit. The transformer steps down 120V line voltage to 24V to power the entire low-voltage control circuit — including the thermostat, contactor coil, gas valve, and control board. When this component fails, nothing in the system responds: the thermostat goes blank, the blower won't start, and no heating or cooling cycle can initiate. It is often the first component to check when a system appears completely unresponsive despite having line power.

  • Specs: Input 120V AC | Output 24V AC | 40VA rated | Primary/secondary wound to OEM factory tolerance | Mounts directly to original bracket
  • OEM vs Generic: The OEM HT01BD236 transformer is wound to Carrier's exact VA and voltage specifications, ensuring stable 24V output under full control-circuit load. Generic transformers may sag under load, causing intermittent lockouts, nuisance tripping, or premature contactor coil failure.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, wire stripper, multimeter to verify 24V output after install. Label or photograph all low-voltage wiring before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed for the Carrier C48A206061 packaged unit. Always verify your unit's control circuit voltage and VA requirements against your data plate before ordering — substituting an undersized transformer can damage downstream components. Our parts specialists are available to confirm fitment before you buy. Order today and get same-day shipping on in-stock OEM parts.

Frequently Asked Questions

Does this Transformer fit my Carrier C48A206061 (HT01BD236) | National HVAC Parts?
Yes. This is the factory-specified OEM transformer for the Carrier C48A206061 (HT01BD236) | National HVAC Parts. 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 C48A206061 (HT01BD236) | National HVAC Parts?
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?
