Carrier 50JZ030310 Defrost Sensor Board
The defrost control board initiates an important defrosting cycle which may be needed in order to continue normal heating and cooling operations. The control board looks to a sensor that can be found near the condenser, in order to make the decision on when the defrost cycle should begin.
What are some indications that my outdoor defrost sensor board is failing?
- Defrost mode has not run for quite some time especially when there is frost on the unit
- The HVAC system could stop operating for the fact of frost blocking the fins on the outside unit
- The primary control board may show an error number if the defrost control board fails

Before buying or ordering, do your due diligence and cross-check the correct model and also make a visual inspection so that you are positive that the proper replacement defrost sensor board is the one being purchased. There is no need to install the part by yourself. Look for a professional locally to do it for you.
