The Goodman B1378701 is a genuine OEM 5-pin wiring harness built as an exact replacement for the APH1543M41AA heat pump and other compatible Goodman/Amana units. This connector links a specific control circuit within the unit, and a damaged or corroded harness can cause intermittent faults, sensor errors, or a unit that fails to start.

Specifications

  • Part Number: B1378701
  • Connector: 5-pin factory harness
  • Type: Low-voltage control wiring harness
  • Fits: Goodman APH1543M41AA heat pump
  • Equipment: Heat Pump

OEM vs. Generic

The OEM B1378701 arrives with the correct keyed connector and factory pin-out, so it drops straight in. Generic alternatives typically require manual splicing that can create loose contacts and nuisance faults. Choosing OEM keeps the repair clean and protects your equipment warranty.

Installation Difficulty

Easy (1 of 5). A quick unplug-and-replace job. Kill power at the breaker first, note the original routing, and seat the new connector fully until it clicks.
