International Comfort Products T9MPD100J20B1 Air Pressure Switch
The function of the switch is to determine whether or not the primary air circulator is circulating the air as it should. An air pressure switch is one of the key safety creations designed to stop injuries or explosions. Some pressure switches are equipped with a manual reset feature, from which it would have to be reset manually before you can continue using the system.
Important Signs that the Switch has Gone Bad
- The blower refuses to run.
- Wrong voltage range being read.
- The proper temp seldom fully attained.
