Carrier 50TFQ004 Air Pressure Switch
The main job of the switch is to determine whether or not the primary air circulator is on and running. Some pressure switches are constructed with a manual reset, which, of course, means that it would have to be reset by hand before the HVAC system will continue. An air pressure switch is one of many other device to keep you from harm.
Signs to Look for when your Pressure Switch is on its Last Leg
- Furnace will not operate.
- System does not achieve the desired temp according to the settings on the thermostat.
- Incorrect volt range reading.

Before you decide on buying or ordering, do your due diligence and cross-check the correct model as well as make a visual inspection in order to be sure the right air pressure switch is being ordered. HVAC pros may have higher labor rates than others so you may want to keep a lookout locally to acquire the best rate if you want to pay bottom dollar.
