International Comfort Products T8MPL125J20A1 Defrost Sensor Board
The defrost sensor board determines when or if to start the defrost sequence if necessary, to remove frost build-up that may accumulate. It is relayed information from a specific sensor which is near the condenser somewhere, in order to ascertain when to begin.
Some warnings the defrost sensor board is on its last leg
- The HVAC system control board could display an error code if the defrost board goes out
- Your system could stop working due in part to the fact that there is too much frost
- Self defrost sequence never kicks in despite that there is a large amount frost on the external unit
