Economizer Installation Wiring for Residential Package Units

Goodman recently issued Service Bulletin SP-038 providing instructions for the installation of an economizer on “M” Series residential package units that do not have a factory installed economizer wiring harness.

From Goodman:

The DP14GM24 – 48 and A/GPG1424 – 48 units have single-stage compressors and use a PCBAG123 single-stage control board. This board does not have an economizer wiring harness connection. Part # 0259G00214 (economizer wiring harness) would be used to connect from the control board and thermostat to the economizer 9-pin connector (see instructions below).
Note: Part # 0259G00214 is factory installed in the DP14GM48 and A/GPG1448 units, but is not on the 2.0 – 3.5 ton 14 SEER gas package models.

To install an economizer on the “M” series package cooling unit use economizer wiring harness (Part # 0259G00213) and on the “M” series package heat pumps models use economizer wiring harness (Part # 0259G00215) to connect from the control board and thermostat to the economizer 9-pin connector (see instructions below).

Gas Package Units (Utilizes harness connector Part # 0259G00214):
1. Connect yellow wire from pin #2 to the Y connection (yellow wire) from thermostat.
2. Connect yellow wire from pin #4 to yellow wire in unit control box (this wire is connected to pin 11 of the 12-pin connector on the control board).
3. Connect blue wire from harness (pin #5) to 24V Common (blue common wire) on unit.
4. Connect green wire from harness (pin #6) to ECON spade on control board.
5. Connect red wire from harness (pin #9) to R terminal (red wire) on transformer.
