Description
Here is how the No Freeze Control board works. Once the temperature of the evaporator coil drops to 29°F, the temperature sensor connected to the board alerts the No Freeze Control board of the low temperature of the evaporator coil, and, as a result, the No Freeze Control board interrupts power to the HVAC unit, shutting it down. At this point, the blue indicator light installed on the board will flash, indicating that the unit has been shut down as the result of the No Freeze Control board having anticipated the freezing up of the evaporator coil. And so the unit will remain, without power and unfrozen, until it has been serviced by a licensed HVAC technician. After having serviced the unit, the technician presses the reset button installed on the No Freeze Control board to restore power to the HVAC unit, at which time the blue indicator light will cease flashing, becoming solid and the HVAC unit, having been serviced, will resume functioning as normal.

The No Freeze Control board is a printed circuit board designed to anticipate the freezing of the evaporator coil in the HVAC unit and interrupt power to the unit in order to prevent the evaporator coil from icing or freezing up.
Many factors can cause the freezing of the evaporator coil; some of main causes are . . .
- Faulty blower fan
- Faulty thermal expansion valve
- Low refrigerant
- Restricted refrigerant
- Clogged air filter
- Restricted air flow
- Low ambient temperature
