Lennox 13ACD-048 Air Pressure Switch
The primary function of the pressure switch is to determine whether the main blower is running properly. This switch is a vital device of the safety system that is in place to keep you safe and keep your family safe. The vast majority of pressure switches made today are issued with a manual reset feature, which, of course, means that it would have to be reset by hand in order for the HVAC system to continue running.
Signs that your Switch is Starting to Fail
- The blower can not function.
- Bad volt range being used by the switch.
- The proper temperature in the house seldom reached.
