OEM Carrier Control Transformer 40VA 120V/24V for Model FZ4ANP061L00AAAA

This OEM replacement transformer (part number HT01CN241) is the factory-specified step-down transformer for the Carrier FZ4ANP061L00AAAA air handler. The transformer converts 120V line voltage to 24V AC to power the entire low-voltage control circuit — including the thermostat, control board, and relay coils. When the transformer fails, the result is a completely unresponsive system: no thermostat display, no contactor pull-in, and no heating or cooling operation whatsoever. A shorted transformer will often blow the control fuse as well, so always inspect and replace the fuse when servicing this part.

  • Specs: 40VA rating | 120V primary / 24V secondary | OEM part number HT01CN241 | Factory-matched output voltage within ±2% tolerance for reliable control circuit operation
  • OEM vs Generic: OEM transformers are wound and rated to exact factory specifications, ensuring consistent 24V output under full load. Generic alternatives may under-deliver voltage under peak demand, causing intermittent lockouts or nuisance fuse failures.
  • Install difficulty: 2/5 — Disconnect power at the breaker and verify zero voltage with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts or spade connectors. Note wire colors and terminal positions before removing the old transformer.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for the Carrier FZ4ANP061L00AAAA air handler. Always verify primary voltage (120V) and VA rating on your unit's data plate before ordering. Need help confirming fitment? Our HVAC parts specialists are available to verify compatibility before you buy — order with confidence and get back up and running today.

Frequently Asked Questions

Does this Transformer fit my Carrier FZ4ANP061L00AAAA?
Yes. This is the factory-specified OEM transformer for the Carrier FZ4ANP061L00AAAA. 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 FZ4ANP061L00AAAA?
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.
