The Goodman 0130M00264 Thermistor Relay is a genuine OEM temperature-sensing control for the DCC300XXX4VVXCAA packaged air conditioner. This relay uses an integrated thermistor to monitor temperature and switch its output contacts based on the sensed condition, managing protective or sequencing functions in the unit's control circuit. Because relay timing and switching thresholds are calibrated to the equipment, the factory part keeps the control sequence operating exactly as designed.
The OEM 0130M00264 carries the correct thermistor curve, contact rating, and terminal layout for a true drop-in. Generic substitutes rarely match the thermistor calibration or pinout, risking nuisance trips or no protection at all. For a temperature-sensing relay, OEM is strongly recommended.
Easy to Moderate (2/5). This is an electrical-only swap — disconnect power, photograph the wiring, transfer the leads to matching terminals, and secure the relay. No refrigerant work is involved. Verify orientation against the original before powering back up.
