International Comfort Products PGMD42H115C Defrost Sensor Board
The defrost sensor board is jobbed with determining when to begin an important defrosting cycle which may be necessary to defrost your outdoor unit. It relies on a defrost sensor located near the condenser to decide when to initiate the defrosting cycle.
Major clues of an ineffective defrost sensor board
- Defrosting has not run for a while even though there is a large amount of frost that makes the unit run like crap
- Your main control board may signify a particular error code produced when the defrost board is bad
- Your system could stop running due in part to frost blocking the airflow outside
