The Goodman 0130M00264 Thermistor Relay is a genuine OEM temperature-sensing control used in DCC300XXX4BXXXAC packaged air conditioner units. This component combines a thermistor sensing element with a switching relay to monitor temperature and energize or de-energize a circuit at a preset threshold — commonly used for compressor or motor protection and staged control. When a thermistor relay drifts or fails, the unit can lose protection or refuse to start, so a direct OEM replacement restores correct operation.
The OEM 0130M00264 matches Goodman's exact resistance curve and switching threshold, so temperature response and timing are identical to factory. Generic relays rarely replicate the thermistor's specific curve, which can cause erratic switching or false protection trips. For a sensing control, OEM accuracy matters.
Easy to Intermediate. This is a plug-in / spade-terminal electrical swap with no refrigerant work. Always disconnect power first; a confident DIYer or HVAC tech can complete it in minutes.
