OEM Goodman Defrost Control Board for ASH130241AA — PCBDM101S

Goodman PCBDM101S Defrost Control Board

The PCBDM101S is the genuine OEM defrost control board for the Goodman/Amana ASH130241AA 13 SEER, 2-ton heat pump. This board is the brain of the outdoor unit: it reads the defrost thermostat, times the defrost interval (typically selectable 30/60/90 minutes), energizes the reversing valve solenoid, and cycles the compressor and outdoor fan to clear frost from the coil during heating operation. A failed board typically shows up as a unit that ices over, won't defrost, or won't switch between heating and cooling.

OEM vs. Generic

The genuine PCBDM101S carries the correct relay ratings, timer logic, and terminal layout your wiring harness plugs into directly. Aftermarket "universal" defrost boards often require rewiring and jumper reconfiguration, and may not honor the factory anti-short-cycle and defrost logic — risking compressor wear.

Install Difficulty: Moderate

Replacement is a plug-and-play swap for anyone comfortable working around 24V/line-voltage terminals: photograph the wiring, kill power at the disconnect, transfer each spade connector one at a time, and set the defrost timer jumper to match the old board. Budget 30–45 minutes. No refrigerant work involved.
