The Goodman B1370738 is a genuine OEM EEP (electrically erasable programmable) time delay relay designed for ARUF018-00A-1 air handlers and compatible Goodman/Amana indoor units. This relay manages the timed sequencing of the blower and electric heat circuits, preventing nuisance cycling and protecting the motor and heater elements during start-up and shut-down. A failed time delay relay commonly shows up as a blower that won't start, runs continuously, or short-cycles.

OEM vs. Generic

The OEM B1370738 is programmed and calibrated to Goodman's exact timing specification, ensuring correct sequencing and full compatibility with the unit's control logic. A generic relay can offer cost savings on basic switching needs, but for a programmable time delay relay we strongly recommend OEM to guarantee the factory timing curve and reliable operation.

Installation Difficulty: Moderate

Replacement involves low-voltage control wiring and typically takes 20–30 minutes. Disconnect all power before servicing. Photograph and label every wire before removal, transfer connections one at a time, and verify against the unit wiring diagram. Because this is a control component, professional installation by a licensed HVAC technician is recommended if you are not experienced with control wiring.
