Product Description


Rheem Ruud Defrost Control Board HSCI 1157-83-1002A

This is a BRAND NEW Rheem/Ruud/Weather King/Corsaire Defrost Control Circuit Board and Defrost Sensor. These are the two most common causes of a heat pump turning into a block of ice. The Kit Part replaces all the part #s listed below. Board comes with wiring instructions in case needed. The new board has the sensors "plug into" the board rather than be soldered in like most of the older models. Thanks for looking and good luck!


The control board is the "brain" of your unit, coordinating and executing the operation of other various components by sending voltage when and where needed. A control board is constantly monitoring sensors and safety switches in the unit.

Replaces Old Part #s:
