GE AZ75H12EACM1 Defrost Sensor Board
The defrost control board will determine when to initiate the defrost sequence which aids to continue normal heating and cooling operations. The control board looks to a specific sensor that can be found near the condenser, in order to make the decision on when the defrost cycle should begin.
Key symptoms of an unhealthy outdoor defrost sensor board
- The HVAC system could not run because of way too much frost build-up
- Your main control board could throw an error signal produced by a failing defrost board
- The defrost sequence refuses to initiate despite the fact that there is quite a bit frost that makes the unit run like crap
