Carrier 58MTA120 Defrost Sensor Board
The defrost sensor board initiates the defrosting phase in order to continue normal heating and cooling operations. It relies on a specific sensor that can be found near the condenser, in order to make the decision on when to initiate the defrosting cycle.
Hints your defrost board needs to be replaced
- Your HVAC system will not run due in part to the fact that there is too much frost
- Unit defrost session refuses to initiate especially when there is a rather large amount of frost on the outdoor unit
- The main control board might give out an error number produced by too much frost
