Goodman ATUF486016 Defrost Sensor Board
The defrost control board is jobbed with determining when to begin an important defrosting cycle which helps to keep your outdoor unit from plugging up. It relies on a temperature sensor which is near the condenser somewhere, in order to ascertain when to begin.
Subtle cues of a poorly performing defrost board
- Defrost session never starts even though there is a large amount of frost built up
- Your main control board may issue a type of error code produced by a bad defrost control board
- Most systems will stop operating because of frost blocking the fins on the outside unit
