Goodman ARUF182416 Defrost Sensor Board
The defrost control board instructs the system to activate the defrosting phase which may be necessary to defrost your outdoor unit. The control board looks to a defrost sensor located near the condenser to make the decision on when the defrost cycle should begin.
Red flags the defrost sensor board needs replacing
- The HVAC system control board might give out an alphanumeric error code when encountering a problem
- Defrosting refuses to initiate even though there is excessive frost that makes the unit run like crap
- AC and heating system could not operate because of the frost issue
