Why is my Jackson Laboratory Equipment sanitizer pump running continuously?
- SSarah BurnsSep 17, 2025
If the sanitizer pump on your Jackson Laboratory Equipment is running continuously, a shorted sanitizer microswitch on the cam timer could be the cause. If there is not 120V between the ORANGE and GREY wires on the sanitization pump motor microswitch when switch is out of the home position, replace the switch. Alternatively, a shorted prime switch might be the issue; if there is not 120 volts between GREY and WHITE/RED wires to prime switch, replace the switch. Lastly, check for a loose or broken wire and tighten connections to the microswitch.
