The Goodman 0130M00138S is a genuine OEM control transformer engineered for the APH1336H41CA heat pump and compatible Goodman/Amana equipment. This transformer steps down incoming line voltage to the 24V control signal that powers your thermostat, contactor coil, and low-voltage safety circuits. A failing transformer is one of the most common causes of a completely dead system, a tripped low-voltage fuse, or a thermostat with no display — replacing it restores full control operation.

Primary voltage: 208/240V
Secondary voltage: 24V
Foot-mount design for standard control-box installation
Direct OEM replacement for APH1336H41CA

OEM vs. Generic

Our OEM Goodman transformer is the exact factory part with correct VA rating, mounting footprint, and lead configuration — no rewiring or adapters required. Aftermarket generics may carry a similar VA rating but often differ in mounting bracket, lead length, or terminal layout, leading to slower installs and potential control faults. For a control component that your entire system depends on, the OEM part is the safe choice.

Installation Difficulty

Moderate — requires basic electrical knowledge. Always disconnect power at the breaker before servicing. Label and transfer the primary and secondary leads one at a time, verify the 24V output with a multimeter, and confirm proper operation before closing the panel. If you are not comfortable working with line-voltage wiring, we recommend a licensed HVAC technician.

Frequently Asked Questions

Does this Transformer fit my Goodman APH1336H41CA — 0130M00138S?

How do I replace the transformer on my Goodman APH1336H41CA — 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.
