OEM Carrier 50VA Control Transformer P201-35150 for Model UPFLOW125UAHAC14

This is the genuine OEM replacement control transformer for the Carrier UPFLOW125UAHAC14 upflow gas furnace. The transformer steps down incoming line voltage (120/208/240 VAC) to a safe 24V signal that powers the control board, thermostat, and all low-voltage safety circuits. When it fails, every downstream component goes silent — expect a completely dead thermostat, a non-responsive control board, or a furnace that won't initiate any heating sequence at all.

Specs: 50VA | Primary: 120/208/240 VAC | Secondary: 12/24 VAC | 60 Hz | Single Phase | CSA Listed | OEM Part # P201-35150
OEM vs Generic: This factory-authorized Carrier/Totaline transformer is wound to exact VA and impedance tolerances. Off-brand transformers frequently run under-rated VA, causing thermal cutout trips and premature control board failure.
Install difficulty: 2/5 — Shut off the main disconnect and verify zero voltage before touching any wiring. Tools needed: flathead and Phillips screwdrivers, multimeter, wire nuts. Label all low-voltage wires before disconnecting. Confirm secondary output reads 24–28 VAC before reassembling panels.
Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for the Carrier UPFLOW125UAHAC14 furnace. Verify your unit's data plate shows a 50VA, 120/208/240-to-24V control transformer requirement before ordering. Our team is available to confirm fitment — reach out before you buy if you have any questions.

Frequently Asked Questions

Does this Transformer fit my Carrier UPFLOW125UAHAC14?

Yes. This is the factory-specified OEM transformer for the Carrier UPFLOW125UAHAC14. 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 UPFLOW125UAHAC14?

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.
