The Goodman 0130M00264 Thermistor Relay is a genuine OEM control component for the DCC3000314HXXXAB commercial package air conditioner. This relay works with the unit's thermistor sensing circuit to switch a load based on temperature feedback, supporting proper staging and protective shutdown of the system. A failed relay can cause no-cool conditions, erratic operation, or a unit that won't respond to demand.
This genuine Goodman OEM relay is matched to the coil voltage, contact rating, and footprint of the original control. Generic substitutes risk mismatched ratings and connector incompatibility, leading to intermittent faults that are difficult to diagnose. OEM is recommended for control-circuit reliability.
Moderate (3/5). Plan 30–45 minutes. The relay is located in the control compartment and requires careful identification of wiring before swap-out. Photograph connections, disconnect power at the breaker, and verify operation after install. Professional installation recommended.
