Carrier 38TZA048 Defrost Sensor Board
The defrost sensor board instructs the system to activate an important defrosting cycle which helps to continue normal heating and cooling operations. The control board depends on a specific sensor located near the condenser to decide when the defrost cycle should begin.
Important hints your defrost board is not going to last much longer
- Most systems will not run due in part to too much frost
- Your main control board may signify an error number referring to a failing defrost control board
- The defrost sequence never runs especially when there is a rather large amount of frost that makes the unit run like crap
