Friedrich VHA09K Defrost Sensor Board
The defrost control board controls when to launch the defrost cycle which actually helps to get rid of the frost that collects on the outdoor unit. The control board relies on a temperature sensor which is near the condenser somewhere, in order to determine when the defrost cycle should begin.
Important clues to watch for in a bad AC defrost sensor board
- Unit defrost session refuses to initiate despite the fact that there is a lot of frost that makes the unit run like crap
- The main control board could signify an error of some type when encountering a problem
- The whole system may cease to operate due to the amount of frost on the outdoor unit
