The Goodman 0130M00105 Defrost Thermostat is a genuine OEM temperature-sensing switch that tells the defrost control board when the outdoor coil on your ASZ130361AE 3-ton 13-SEER heat pump has iced over. Clamped to the coil tubing, it closes at a low set temperature to initiate a defrost cycle and reopens once the coil warms — protecting heating efficiency and preventing coil damage during winter operation.
The OEM 0130M00105 is calibrated to Goodman's exact open/close temperature spec, ensuring the defrost cycle fires at the right coil temperature. Generic bi-metal switches often carry different trip points, which can cause premature, delayed, or missed defrost cycles — leading to a frozen coil and lost heating capacity.
A quick clip-and-connect repair. Kill power at the disconnect, unclip the old sensor from the coil, transfer the wire leads, and clip the new one in the same location. No tools beyond a nut driver and no refrigerant work needed — typically under 20 minutes.
