The Goodman 0130M00105 Defrost Thermostat is a genuine OEM replacement component engineered for ANZ130601AB heat pump systems. Mounted to the outdoor coil, this defrost thermostat senses coil temperature and signals the control board to initiate and terminate a defrost cycle. When it fails, the outdoor unit can ice over, lose heating capacity, or run wasteful defrost cycles that drive up energy costs.
This is a factory-original Goodman part built to the exact temperature-trip specification your control board expects. Generic aftermarket thermostats often trip at slightly different set points, leading to premature or delayed defrost cycles. Choosing OEM guarantees correct timing, proper fit, and full compatibility with your existing wiring harness.
Difficulty: Easy (DIY-friendly). Most homeowners with basic tools can replace this part in 15–20 minutes: disconnect power, note the two spade wire connections, unclip the old thermostat from the coil, and install the replacement in the same position. Always confirm power is off at the disconnect before servicing.
Backed by genuine Goodman quality. Order the correct part the first time for reliable, efficient heat pump operation all winter long.
