International Comfort Products PYMC36G5 Air Pressure Switch
The main function of the pressure switch is to figure out if the blower is blowing air. A lot of switches are designed with a reset that is manual instead of automatic, which means you have to physically reset it or else the system will cease to function. This is one of the critical mechanisms designed to keep you from harm.
Symptoms to Look for when the Switch is on its Last Leg
- The proper temperature indoors seldom attained.
- The furnace can not run.
- Inaccurate voltage being read from the pressure switch.
