Amana-Goodman 0130M00138S Transformer

The Amana-Goodman 0130M00138S Transformer is a critical electrical component designed for high-reliability voltage step-down in HVAC systems. This 40VA control transformer features a primary input of 208/240V and a secondary output of 24V, providing the stable power necessary for contactors, boards, and thermostats. As a direct OEM replacement transformer, the 0130M00138S supersedes legacy part numbers 0130M00138 and B1141643. Engineered for durable performance in demanding Amana and Goodman furnaces and air handlers, it ensures precise power distribution across the control circuit. The multi-tap primary configurations allow for versatility during field installation, while the 40VA rating provides sufficient overhead for standard residential 24V accessories. For technicians, utilizing this HVAC 24V transformer ensures strict adherence to manufacturer specifications, maintaining the integrity of the furnace control circuit power supply without the risks associated with universal aftermarket alternatives.

• Direct OEM Fit: Drop-in replacement for part numbers 0130M00138 and B1141643.
• High Compatibility: Designed specifically for Amana and Goodman residential heating and cooling units.
• Stabilized Output: Constant 24V secondary voltage ensures reliable engagement of contactors and relays.
• Robust Construction: Built to handle the high-heat environments common within 40VA HVAC applications.

Can the 0130M00138S replace a 30VA transformer?
Yes, as long as the voltage ratings match, a 40VA transformer provides a higher load capacity than a 30VA unit and can safely replace it.

What does the 1141643 cross-reference to?
The B1141643 is the older version of this component; the 0130M00138S is the current manufacturer-recommended replacement.

How do I wire this for 208V versus 240V systems?
Technicians must verify the primary lead configurations on the wiring diagram to ensure the correct tap is used for the source voltage to maintain 24V output.
