Goodman B1370738 EEP Time Delay Relay

The Goodman B1370738 is a genuine OEM EEP time delay relay for the ARUF048-00A-1 air handler and compatible Goodman/Amana models. This control delays blower start-up and ramps fan operation on heating and cooling calls, improving comfort, efficiency, and component longevity by preventing cold-air blow at start and harvesting residual heat at shutdown. A failed time delay relay causes symptoms like a blower that won't start, runs continuously, or cycles incorrectly.

Brand: Goodman (fits Amana equivalents)
Type: EEP electronic time delay relay
Function: Blower on/off time-delay control
Fits: ARUF048-00A-1 series air handlers

OEM vs. Generic

The genuine Goodman OEM relay is programmed with the exact delay timing and terminal pinout the ARUF048 control circuit expects. Aftermarket relays may use different timing curves or wiring, leading to short-cycling or comfort complaints. For control components, OEM ensures correct sequencing.

Installation Difficulty

Moderate (3/5) — Requires disconnecting power, labeling and transferring low-voltage wiring, and mounting the relay. Plan for 20–40 minutes. Professional installation recommended.
