The Goodman PCBDM101S defrost control board is the genuine OEM circuit board that runs the defrost cycle on the ASH130361AA heat pump. It monitors the defrost thermostat, times the compressor run between defrost cycles, energizes the reversing valve solenoid, and controls the outdoor fan so the coil sheds ice in cold weather without wasting energy or icing over.
The OEM PCBDM101S is pin-matched to the ASH130361AA harness and pre-configured with Goodman's defrost logic, so it drops in without rewiring or jumper guesswork. Universal defrost boards exist but require adapting the connector and re-verifying timing pins — a common source of nuisance defrost faults. For a reliable factory match, OEM is the safe choice.
Moderate (3/5). No refrigerant work needed. Disconnect power at the breaker, photograph the wiring, transfer the low-voltage and line-voltage leads one at a time, and set the defrost timing jumper to match the original. A capable DIYer with a wiring photo can complete this in about 30 minutes.
