Genuine Goodman 0130M00138S 40VA Control Transformer

The Goodman 0130M00138S is a 40VA control transformer that supplies the 24-volt low-voltage circuit on Goodman CPC036XXX3DXJXBA and compatible CPC036-series air conditioner package units. It steps line voltage down to the 24 VAC that powers the thermostat, relays, contactor coil, and control board. A failed transformer is one of the most common causes of a completely dead system — no thermostat display and no response to a cooling call.

Specifications

OEM Part Number: 0130M00138S
Output Rating: 40 VA
Secondary Voltage: 24 VAC
Type: Step-down control transformer
Brand: Goodman
Fits: CPC036XXX3DXJXBA and compatible CPC036 series

OEM vs. Generic

The genuine Goodman transformer matches the exact VA rating, primary tap voltage, and mounting bracket of your original. An undersized generic (lower VA) can overheat and fail when driving multiple loads, while mismatched primary taps can produce incorrect 24V output. The OEM part is sized correctly for the CPC036 control load.

Installation Difficulty

Easy to Moderate. Typically a bracket-mount swap with primary and secondary lead connections — about 20–30 minutes. Verify the correct primary tap for your supply voltage, label all wires, and disconnect power before servicing.

Frequently Asked Questions

Does this Transformer fit my Goodman CPC036 — 0130M00138S?

Yes. This is the factory-specified OEM transformer for the Goodman CPC036 — 0130M00138S. 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 Goodman CPC036 — 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.
