International Comfort Products C8DNL075F16A1 Defrost Sensor Board
The defrost sensor control board commences the defrost cycle which may be needed in order to continue normal heating and cooling operations. The defrost board looks to a specific sensor located somewhere by the condenser to verify when the defrost cycle should begin.
Symptoms your defrost board should need replacing
- AC and heating system could stop operating due to way too much frost build-up
- The main control board may issue a type of error code produced when the defrost control board fails to receive a signal
- The defrost sequence has not run for a while even though there is quite a bit frost on the unit
