Whynter ARC-122DHP Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin an important defrosting cycle which aids to get rid of the frost that collects on the outdoor unit. The control board looks to a specific sensor that can be found near the condenser, in order to verify when to initiate the defrosting cycle.
Some clues the AC defrost sensor board will not last the year
- The AC may not operate for the fact of too much frost
- The main circuit board could signify an error of some type produced by too much frost
- The defrost feature never runs even though there is excessive frost on the outdoor unit
