How to Really Test a Low Water Cut Off Probe

[@pipers255]

my company switched me over from plumbing that I’ve been doing all my life to maintenance on boilers to service, and you just taught me something Great work

[@theapprenticesurvivalguide]

thank you! i'm glad you found it helpful!

Is there a typical life span on one of these probes? Are ]you changing based on the gunk build up?

What is that black round/balloon thing that you cleaned out? Does that have to be cleaned out annually? If so, do I need to buy gaskets every time I do that?

My lwco hydro level 400 has a slight dimmed light at all times, it does turn bright orange when water is low and shuts boiler off, could it be the reason why my McDonnell-Miller feeder continues to feed more then one cycle because probe is not grounded properly and causing the slight dimmed orange? Thanks

I was wondering if you can give me some input on, I have a new steam boiler McClain 35 series with a 400 water cut off , I installed with a friend a new McDonnell miller universal 24v water feeder and when I test to fill when water is low it fill to the glass line then it pauses for a few and starts filling again to the point of overflow so I have to shut it off because it repeats the process about 4 times before it stops , what do you suggest is going on ? Thanks

You lost me when you set the meter to Ohms but then got a measurement in Volts. My new probe measures 7.3kOhms to 7.6kOhms after counting to 10 secs. This is with the boiler water hot after a burn cycle. It seems to be like measuring the resistance of a capacitor where the longer you test it the higher the resistance goes, as if it is charging up during the test procedure. Maybe we should be measuring capacitance?

Let me guess there was an auto feed on the boiler?

Hi sir, what's the best electricy for this probe? AC or DC? i've tried using DC 12v but it decrease become DC 6v. i've also tried using DC 12v it also decrease become 8-12v right now i'm still waiting for some parts using AC 24v, is it safe? Thanks for your sharing

All the ones that I work on are so old they have a float type low water cutoff.

Good video

good ole fail safes... when they fail...

Remove and clean every year.
