International Comfort Products T8MPV050B12C1 Defrost Sensor Board
The defrost sensor control board controls if and when to commence the defrosting phase which may be necessary to get rid of the frost that collects on the outdoor unit. The control board depends on a specific sensor located near the condenser to ascertain when the defrost cycle should begin.
Red flags of a poorly performing defrost board
- The main circuit board could display an error number when encountering a problem
- AC and heating system could not operate at all because of the frost blocking the flow of air
- Defrost session never kicks in especially when there is a rather large amount of frost built up
