Mitsubishi MSY-A24NA Defrost Sensor Board
The defrost control board will begin the defrosting phase if necessary, to get rid of the frost that collects on the outdoor unit. The control board is relayed information from a defrost sensor which is near the condenser somewhere, in order to make the decision on when to initiate the defrosting cycle.
Symptoms your defrost board needs a replacement ASAP
- Defrost mode does not begin especially when there is a rather large amount of frost in the way
- The system will not run due to the fact of frost blocking the airflow outside
- The control board might give out an error number produced when the defrost board is bad

Before you decide on buying or ordering do your best and double check the correct model as well as make a visual inspection so that you are positive that the right defrost sensor board is being ordered. You do not have to install it yourself. Consult with a professional in your town or city to hire and install the part for you.
Feel free to download your manual for help.
