The Goodman 0130M00138S control transformer is a genuine OEM step-down transformer for Goodman CPC048XXX1DXXXBA air conditioning units. It converts incoming line voltage down to the 24-volt secondary that powers the thermostat, contactor coil, and control board. A dead transformer means no 24V control power — the system won't start at all. This OEM replacement restores the control circuit.

Specifications

Part number: 0130M00138S
Secondary output: 24 VAC (low-voltage control)
Typical rating: 40 VA Class 2 control transformer
Primary: Multi-tap line voltage (verify your unit's primary against the old transformer)
Mounting: Factory foot/bracket
Fits: Goodman CPC048 series

Confirm the VA rating and primary voltage taps stamped on your existing transformer before installing.

OEM vs. Generic

The genuine OEM 0130M00138S matches Goodman's primary tap configuration and VA capacity, avoiding the undersizing that causes generic transformers to overheat. A correctly sized OEM transformer runs cool and lasts the life of the unit.

Installation Difficulty

Easy to Moderate. Cut power at the disconnect, label and transfer the primary and 24V secondary leads to the matching taps, and remount. Use a multimeter to confirm 24V output before restoring the covers. About 20–40 minutes.

Frequently Asked Questions

Does this Transformer fit my Goodman CPC048 — 0130M00138S?

How do I replace the transformer on my Goodman CPC048 — 0130M00138S?

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 Goodman 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 Goodman 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.
