A customer froze up a cabin where a Noble is installed, and glycol was leaking out of the boiler. It turns out the domestic water in the exchanger froze, deformed it, and it now leaks at both valve connections. I searched for information and here's your video. Just what I needed. Thanks!
@@FIA_Incyeah no. As my 83yr old sick ma & my illness (should go to hospital but can't cuz every day it breaks down & EVERYONE has been here for hours over days & now weeks. BRAND NEW. Your tech support is crap. $12K from 2 sick old people whose new heater doesn't work & you've sent NO ONE to help. SHAME ON YOU
This video was amazing! Thank you for sharing this knowledge! My Lochinvar Noble boiler currently has a fail ignition fault. It's been running like a top for three years then just stopped. I confirmed I have spark. I confirmed 26 volt from the board to the gas valve. My boiler goes from pre purge, runs 26 volt to the gas valve, I get ignition (visible) for 0.5 seconds, then boiler goes into post purge and gas valve goes to 0 volt. Repeat 3 more times, error and lockout. I don't have a manometer to check the gas valve unfortunately, but that may be the culprit. Odd to me that I can see it fire through the sight glass and it still shuts off though...any ideas from the peanut gallery???
It’s hard to pinpoint the exact cause for this as there are many things that could be the issue. When was the unit serviced…i.e… burner cleaned, etc..If you do not know I would start there. You can find your local representatives here www.lochinvar.com/locator/
Typically a plastic venturi rotting out or physically breaking down means it is being exposed to exhaust gas recirculation, a laundry dryer vent exhaust or some other chemical that could be drawing into the intake of the boiler.
Robb, I have a Lochinvar Combi Boiler installed and live in the Haverhill area, can you recommend a local company who services this product. Mine was installed in 2019 and the contractor who installed it is no longer in business. I am having low flo issues with the DHW.
Great video! I’m having issues with ignition and fan noise on my N199. Do you have a link or video of your service you talk about at the end of this video? I need to dig into mine and it would be very helpful.

Has anyone has the issue of flame fail while running? Im going back on a Noble we installed about year ago that is having this issue. In high fire no issue but when it ramps down the flame drops out.
Does the unit still operate normally? If it does, I suspect it is not the main control board it would probably be the user interface or the ribbon cable between the user interface and the main control board. I suggest checking all the connections from the display board to the main control board. Power it down then power it back up and see if it goes away after rechecking the connections. Unfortunately there is no way to field test the boards. The main control board is the “brain” and is where the logic takes place, the user interface or display screen is only a window to see into the brain….so to speak.

There could be many things to create the sound so it is hard to say exactly what the issue could be. Has the noise been there since the unit was installed? Is the noise really emanating from the fan? Does the sound ever go away? Try and take the air intake off of the unit and see if it goes away. There could be something that got sucked into the fan. The fan itself could be failing. Is the unit vented properly? Any obstruction? With the unit in “shutdown” or “Standby” mode per the display screen, pull the 4 wire modular connector on the fan. This will turn the fan on at full speed without the unit firing…..does it still make the noise? You can find your local representatives and service contractors here: www.lochinvar.com/locator/
Flow may not be high enough to trigger DHW, verify DHW flow is at least 0.4 gpm You can find your local representatives and service contractors here: www.lochinvar.com/locator/

I’m seen plastic venturis completely rot out anyway to fix that? Like the plastic crumbles apart

sounds like the venturi needs to be cleaned and a possible combustion adjustment. Contacting your local contractor would be our recordation.
My boiler is working fine but the display screen keep rebooting itself, what’s the solution? Do I have a bad control board? @FIA_inc

It was the interface board. Can the inlet valve assembly be replaced? What’s the part number?
Anyone ever have issues with the fan making a very loud High pitch sound?
I replaced the fan for short money. And the issue went away.
