How is a flow switch used in a central heating system?
Flow switches are used in many other applications, such as: The flow switch triggers an alarm when the supply gets off. When there is insufficient flow, the electric motor will shut down. The flow switch also gets used in air conditioning and ventilator units. In the central heating systems, the flow switch gets used.
How to test if your flow switch is bad?
You can test the continuity of the flow switch using a Voltmeter or Ohmmeter. Continuity is open if there is no flow. Alternatively, continuity is close if sufficient water flow is detected. If you don’t have access to a VOM, then perhaps the below might help. You can use the two wire tel cord if available.

How does a flow switch in a pipe work?
This device has an internal piston which activates the switch. The flow enters a port and adds pressure to the magnetic poppet; once this pressure hits the preset level, the switch will turn off. Attached to the outside of a pipe, ultrasonic sensors send signals when it detects a change in the flow.

Can you bypass the flow switch on a gas heater?
Do not bypass the Flow Switch: this could cause a potential dryfire of the heater and melt down of the heater system. If your control panel is “Solid Flo” then the Flow Switch is defective and needs to be replaced. 4. FL1 or FL 2 Error Code FL1: Flow or pressure switch not closed when pump is running. Heater is deactivated.

How to do a continuity test on a hot water heater?
Continuity Test or Ohms test: Turn off the power to the spa and with your probe set to a continuity check, probe the 2 heater terminals at the same time. One probe on one terminal, and the other on the other terminal. Using an Ohm meter, on its lowest setting, measure the resistance between the 2 heater terminals. The typical range is 9-12 Ohms.
