OEM Carrier 40VA Control Transformer for Model P110SBP2312A

This is the OEM factory-replacement control transformer for the Carrier P110SBP2312A unit, sold under part number P201-2201. The transformer steps down 120V line voltage to 24V to power the entire control circuit — including the thermostat, contactor coil, and control board. When this transformer fails, the result is a completely unresponsive system: the thermostat goes dark, no relays click, and nothing operates. It is often the first component to check when a system shows zero control-side activity.

  • Specs: 40VA rated | Primary: 120V | Secondary: 24V | Class 2 transformer | Direct OEM replacement for P201-2201
  • OEM vs Generic: The OEM P201-2201 transformer is wound to exact Carrier specifications with built-in thermal overload protection. Generic alternatives frequently lack proper VA ratings, leading to premature failure under full control-circuit load.
  • Install Difficulty: 2/5 — Disconnect all power before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V output after install). Always label or photograph wire connections before removal.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: Designed as a direct OEM fit for Carrier model P110SBP2312A. Verify your unit's control board input voltage and VA requirements against your data plate before ordering.

Frequently Asked Questions

Does this Transformer fit my Carrier P110SBP2312A?
Yes. This is the factory-specified OEM transformer for the Carrier P110SBP2312A. 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 P110SBP2312A?
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?
