Carrier 58MXA040 Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin an important defrosting cycle which assists to keep the outdoor unit free from frost build-up. The defrost board relies on a sensor located near the condenser to make the decision on when to begin.
Hints to watch for in a failing Carrier defrost sensor board
- The primary control board could display an error of some type produced by a bad defrost control board
- Your system could stop operating because of the safety issue that the frost poses
- The defrost feature will not kick in especially when there is a rather large amount of frost on the outdoor unit
