OEM Carrier 40VA Control Transformer HT01BD236 for Model C50A206061

This OEM Carrier transformer (part number HT01BD236) is the factory-specified replacement for the Carrier C50A206061 packaged commercial rooftop unit. The transformer steps down line voltage from 120V to 24V to power the low-voltage control circuit — including the thermostat, contactor coils, and control board. When this transformer fails, the entire control circuit goes dead: the thermostat loses power, the system won't respond to calls for heating or cooling, and no fault codes will appear on the board because there is simply no voltage to drive any component.

  • Specs: Input 120V AC | Output 24V AC | 40VA rating | OEM part number HT01BD236 | Factory-matched for Carrier C50A206061 packaged rooftop units
  • OEM vs Generic: This is a genuine OEM Carrier transformer wound and insulated to exact factory specifications. Generic replacements may use lower-grade core laminations and thinner windings that overheat under sustained load, leading to premature failure and potential control board damage from voltage sag.
  • Install difficulty: 2/5 — Always disconnect all power before servicing. Tools needed: flathead and Phillips screwdrivers, wire stripper, multimeter (verify 24V output after installation). Photograph all wiring connections before removal. Transformer is typically located in the control panel section of the unit.
  • Warranty: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier C50A206061 packaged commercial rooftop unit. Before ordering, verify your existing transformer's input/output voltage and VA rating on the unit's data plate or original transformer label. Need fitment confirmation? Our HVAC parts specialists verify compatibility before you order — contact us anytime.

Frequently Asked Questions

Does this Transformer fit my Carrier C50A206061?
Yes. This is the factory-specified OEM transformer for the Carrier C50A206061. 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 C50A206061?
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.
