International Comfort Products GDJ100M12A1 Air Pressure Switch
The actual job of the pressure switch is to sense whether the blower fan is blowing air. A lot of switches are constructed with a manual reset, which means you have to physically reset it or else the system will cease to function. This switch is part of the safety system in place to keep you safe from potential hazards in the house.
Signals that the Pressure Switch is Starting to Fail
- Wrong voltage being read from the pressure switch.
- The blower fan is unable to operate.
- The set temperature indoors is hardly ever fully attained.
