The Goodman 0130M00138S is a genuine OEM control transformer engineered as a direct-fit replacement for the APH1330H41CA heat pump and compatible Goodman/Amana systems. It steps line voltage down to the 24V low-voltage power that runs your thermostat, control board, contactor coil, and safety switches. A dead transformer is a classic cause of a completely unresponsive system — no thermostat display, no call for heat or cool.

Specifications

Rating: 40VA
Secondary output: 24V (low-voltage control)
Primary: line voltage (multi-tap style, model dependent)
OEM Part Number: 0130M00138S
Brand: Goodman (Amana compatible)
Equipment: Heat Pump — model APH1330H41CA
Fit: Direct OEM replacement

OEM vs. Generic

The OEM 0130M00138S delivers the exact 40VA capacity and terminal/tap configuration this control circuit expects, mounting cleanly with no bracket modifications. Under-rated generic transformers can overheat and fail early when driving the contactor coil plus accessories, while mismatched taps risk under- or over-voltage on the control board. OEM ensures the correct load capacity and a clean bolt-in fit.

Installation Difficulty

Easy to moderate — a confident DIYer can handle it, though a technician is recommended. Involves shutting off power, labeling and transferring primary and 24V secondary leads, and remounting. Verify secondary output at 24–28V with a multimeter after install. Typical time: 15–30 minutes.

Always disconnect power before servicing and confirm the OEM part number before ordering.

Frequently Asked Questions

Does this Transformer fit my Goodman APH1330H41CA — 0130M00138S?

How do I replace the transformer on my Goodman APH1330H41CA — 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.
