Panasonic CS-E12NKUAW Defrost Sensor Board
The defrost sensor board is jobbed with determining when to begin the defrost cycle which may be necessary to keep the outdoor unit free from frost build-up. The defrost board depends on a sensor located near the condenser to determine when to begin.
Subtle hints the defrost sensor board is not going to last much longer
- Air conditioning may stop operating for the fact of way too much frost build-up
- Your main control board might give out an alphanumeric error code produced by a bad defrost control board
- Defrost session never kicks in despite the fact that there is quite a bit frost that has built up
