OEM Carrier 40VA Control Transformer 120V–24V for Model P110200

This OEM replacement transformer (part number P201-2201) is the factory-specified control circuit transformer for the Carrier P110200 system. The transformer steps down 120V line voltage to the 24V signal voltage that powers your thermostat, contactor coil, gas valve, and control board. When it fails, the entire control circuit goes dead — the thermostat goes blank, the system refuses to respond to any call for heating or cooling, and no error codes are displayed because the board itself has no power.

  • Specs: 40VA rating | Primary: 120V AC | Secondary: 24V AC | Factory-matched OEM part number P201-2201 | Designed for continuous-duty HVAC control circuits
  • OEM vs Generic: This OEM transformer is wound to exact factory VA and voltage specifications. Undersized or off-tolerance generic transformers can overheat, trip thermal cutoffs, and damage downstream control boards — making OEM the only reliable choice for this application.
  • Install difficulty: 2/5 — Disconnect power at the breaker before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 24V output after install). Label or photograph all wire connections before removal.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier P110200 system using OEM part number P201-2201. Always verify your existing transformer's VA rating and primary/secondary voltages on the unit's data plate or wiring diagram before ordering. Our parts specialists are available to confirm fitment — order with confidence.

Frequently Asked Questions

Does this Transformer fit my Carrier P110200 — P201-2201?
Yes. This is the factory-specified OEM transformer for the Carrier P110200 — P201-2201. 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 P110200 — P201-2201?
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?
