The Goodman 0130M00264 Thermistor Relay is a genuine OEM control component for the DBC3004VDDCAA air conditioner and compatible Goodman/Amana systems. It pairs a temperature-sensing thermistor with a switching relay to monitor a critical circuit point and energize or de-energize a load based on temperature — supporting protective lockouts and proper sequencing of the unit's electrical controls.
The OEM Goodman relay ships with a thermistor curve and contact rating matched to the original control logic, so switch points and timing behave exactly as designed. Generic alternatives may save money but can use substitute thermistors with different resistance curves, leading to early or late switching — choose OEM for predictable control behavior.
Easy (1/5). Typically a plug-in or spade-terminal swap with no refrigerant work. Disconnect power at the disconnect, photograph wiring, and transfer leads one at a time to avoid mis-wiring.
