Goodman GKS90904CX Defrost Sensor Board
The defrost control board initiates an important defrosting cycle which may be necessary to defrost your outdoor unit. It is relayed information from a sensor located somewhere by the condenser to agree when the defrost cycle should begin.
What are the signs that the defrost board really needs to be replaced?
- The defrost feature refuses to run even though there is a large amount of frost that makes the unit run like crap
- AC and heating system could stop functioning at all because of the frost blocking the flow of air
- The HVAC system control board may signify a type of error code produced by too much frost
