The Goodman 10135604 Relay is a genuine OEM switching relay for the ASZ130421AC 13 SEER heat pump. It uses a low-voltage coil signal from the control board to open or close a higher-current set of contacts, energizing components such as the reversing valve circuit, fan, or auxiliary load on command. When a relay's contacts pit or its coil burns open, the affected component stops responding — a no-heat, no-cool, or stuck-defrost symptom that often traces back to this inexpensive part.

Specifications

Part Number: 10135604
Part Type: Control / Switching Relay
Fits Model: ASZ130421AC (Goodman heat pump)
Function: Coil-actuated contact switching for control-circuit loads
Fit: Direct OEM replacement — matched coil voltage and terminals

OEM vs. Generic

This genuine Goodman OEM relay matches the factory coil voltage, contact rating, and terminal layout exactly. A generic relay with a different pin arrangement or lower contact rating can miswire the circuit or weld shut under load. OEM ensures correct switching and terminal compatibility.

Installation Difficulty

Easy (2/5). About 15 minutes. Cut power at the disconnect, label and photograph the existing wire terminals, then transfer each spade connector to the matching terminal on the new relay one at a time to avoid mix-ups. No refrigerant work required. Restore power and confirm the switched component energizes on call.
