Goodman B1378701 5-Pin Wiring Harness

The Goodman B1378701 is a factory-original 5-pin wiring harness for Goodman and Amana AEPT036-00C-1A air handlers. This pre-terminated connector loom provides correct, color-coded connections between the control board and a component circuit within the air handler. Brittle insulation, scorched terminals, or loose pins can cause intermittent operation and nuisance faults; replacing the harness with the genuine OEM part restores clean, reliable signal and power.

Specifications

Connector: 5-pin plug
Part type: OEM component wiring harness
Function: Connects control board to air handler component
Fits: Goodman/Amana AEPT036-00C-1A air handlers

OEM vs. Generic

OEM B1378701 matches Goodman's exact connector, pin count, and wire gauge for a true plug-and-play fit with no splicing. Aftermarket harnesses may have mismatched pinouts or thinner wire that can fault or overheat. For any wiring component, the genuine OEM harness is the safe choice.

Installation Difficulty

Moderate (2/5). Cut power first and photograph the original connections. The 5-pin plug is straightforward to swap once accessed. If you're unsure about control wiring, have a qualified HVAC technician install it.
