How to fix HIGH ALARM flashing on CBS S1500?
- WwhitedominicAug 17, 2025
If the HIGH ALARM text is flashing and there's an audible alarm on your CBS Storage, it means the liquid level in the vessel is too high. First, push the STOP switch. If it continues to fill, the solenoid valve may be stuck open. Try pushing the FILL and STOP switches 15 to 20 times to unstick it. If that doesn't work, turn off the manual valve on the liquid nitrogen supply tank and let the solenoid valve warm up. Then, reopen the manual valve to see if it works. If not, the solenoid valve might need to be disassembled for service. Alternatively, there may be an obstruction in the solenoid valve. In that case, remove the solenoid valve and disassemble it for service.
