Panasonic CU-KS18NKUA Defrost Sensor Board
The defrost sensor control board commences the defrost sequence if necessary, to rid your unit of frost that can build up. The defrost sensor board looks to a sensor which is near the condenser somewhere, in order to make the decision on when the defrost cycle should begin.
Warnings the AC defrost sensor board will not last the year
- The defrost sequence never begins despite the fact that there is a lot of frost built up
- The whole system may stop functioning at all because of the fact that there is too much frost
- The main control board may issue an error code produced when the defrost control board fails to receive a signal
