SPT TN-12E Air Pressure Switch
The function of an air pressure type switch is to figure out if the primary air circulator is running properly. This is just one of many facets of the HVAC safety checks that are dedicated to keep you safe. A good number of pressure switches today are constructed with a manual reset, which forces the system to be reset physically before the system will continue its normal operation.
Symptoms to Look for when the HVAC Air Pressure Switch is Beginning to Fail
- The furnace refuses operate at all.
- Incorrect voltage reading.
- The set temperature indoors is never reached.
