OEM Carrier Control Transformer 40VA 208/230V–24V for Model PF1MNC036008AAAA

This OEM Carrier transformer (part number HT01CN241) is the factory-specified 24V control circuit transformer for the Carrier PF1MNC036008AAAA fan coil and air handler unit. Its sole job is to step the line voltage down from 208/230V to a safe 24V signal that powers every component in the control circuit — thermostat, relay coils, reversing valves, and the control board itself. When this transformer fails, the entire low-voltage control circuit goes dark: the thermostat loses power, the system stops responding to calls for heating or cooling, and nothing works — no error codes, no operation. Replacing it with the correct OEM unit restores the full 24V circuit to factory spec instantly.

  • Specs: 208/230V Primary | 24V Secondary | 40VA Power Rating | OEM Part# HT01CN241 | Direct drop-in replacement, no modification required
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact OEM voltage and VA tolerances. Generic transformers often run under-rated VA capacity, causing premature failure under full control-circuit load — especially in multi-stage or communicating systems.
  • Install difficulty: 2/5 — Disconnect all power before beginning. Tools needed: flathead and Phillips screwdrivers, wire nuts or spade connectors, multimeter to verify 24V output post-install. Photograph all wiring before disconnecting. A qualified HVAC technician is recommended for safety.
  • Warranty: 1-year OEM manufacturer's warranty. In stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: Confirmed fit for Carrier model PF1MNC036008AAAA fan coil / air handler. Verify your unit's data plate lists a 208/230V primary and 24V, 40VA secondary before ordering. Our HVAC parts specialists are available to confirm fitment — reach out before you order if you have any questions. Order today and get same-day shipping!

Frequently Asked Questions

Does this Transformer fit my Carrier PF1MNC036008AAAA?
Yes. This is the factory-specified OEM transformer for the Carrier PF1MNC036008AAAA. 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 PF1MNC036008AAAA?
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?
