The Goodman 0130M00264 Thermistor Relay is a genuine OEM control component for DCC3000313WMXXAA commercial package air conditioning units. This relay works in conjunction with a thermistor temperature-sensing circuit to switch a load (such as the compressor or fan circuit) based on measured temperature, providing accurate, automatic control and protection against overheat conditions. Using the correct OEM relay ensures the switching logic and coil voltage match your unit's control sequence.
This authentic Goodman part is matched to your unit's coil voltage, contact rating, and terminal layout. Generic relays may differ in pinout or switching threshold, causing erratic operation or control-board faults. For a sensing-and-switching component, OEM fitment is strongly recommended.
Easy to Moderate — No refrigerant work required. Disconnect power, photograph the wiring, swap the relay in its mount, and reconnect terminals exactly. A DIY-capable owner with electrical comfort can manage this; otherwise call a technician.
