Goodman B1378701 5-Pin Wiring Harness

The Goodman B1378701 is a genuine OEM 5-pin wiring harness engineered as a direct-fit replacement for the Goodman AEPF303616AA air handler. This harness carries the low-voltage and control signals between the air handler's control board and its connected components. A cracked, melted, or corroded harness is a common cause of intermittent operation, no-heat/no-cool faults, and blower failures — replacing it with the correct OEM part restores reliable, code-compliant connections.

Specifications

Part number: B1378701
Connector: 5-pin keyed plug
Brand: Goodman (also fits select Amana air handlers)
Compatibility: AEPF303616AA air handler
Type: OEM low-voltage control harness

OEM vs. Generic

The OEM B1378701 uses factory-spec wire gauge, keyed connectors, and pin spacing that exactly match the AEPF303616AA, eliminating the miswiring risk of universal harnesses. Generic harnesses may require crimping and re-pinning. For a plug-and-play repair, OEM is the safe choice.

Installation Difficulty

Easy. Disconnect power, unplug the old harness, route and seat the new keyed connectors, and restore power. No special tools required. Typical install time: 10–15 minutes for a qualified technician.
