The Goodman 0130M00105 Defrost Thermostat is a genuine OEM temperature-sensing switch for the ASZ130421AB 13 SEER heat pump. Clipped to the outdoor coil, it signals the defrost control board when the coil drops cold enough to accumulate frost, initiating a defrost cycle so the unit keeps heating efficiently in winter. A failed defrost thermostat is a common cause of an iced-over outdoor coil, weak heating, and short-cycling.

Specifications

Part Number: 0130M00105
Part Type: Defrost Thermostat / Coil Temperature Switch
Fits Model: ASZ130421AB (Goodman heat pump)
Function: Closes on falling coil temperature to enable defrost
Fit: Direct OEM replacement — factory clip and lead length

OEM vs. Generic

This genuine Goodman OEM thermostat is calibrated to the exact close/open temperature set points Goodman engineered for this coil. Generic snap-discs may switch at the wrong temperature, causing unnecessary defrost cycles that waste energy or missed cycles that let ice build up. OEM guarantees correct calibration and lead terminals.

Installation Difficulty

Easy (2/5). Roughly 15–20 minutes. Cut power at the disconnect, unclip the old sensor from the coil tube, unplug the two spade terminals, then clip and reconnect the replacement in the same location. No refrigerant handling required. Verify a solid metal-to-tube contact so the sensor reads coil temperature accurately.
