Nordyne Cooling Fan Relay 90-380

Nordyne / Nortek / Miller 90-380 SPNO & SPNC 24V Relay | OEM

The Nordyne 90-380 is a genuine factory-authorized single-pole, double-throw (SPDT) relay designed for Nordyne, Miller, and Intertherm HVAC systems. As an Original Equipment Manufacturer (OEM) component, it features both Normally Open (NO) and Normally Closed (NC) contacts, allowing it to switch power between two different circuits—typically used for fan motor speed switching or auxiliary heat sequencing.

This heavy-duty 24V relay is engineered to handle the high-amperage loads of blower motors while ensuring a reliable electrical connection within your furnace or air handler.
