How to test flame sensing hsi/sensor
I was hoping someone could explain how it work and how to test flame sensing on a boiler when the hot surface is used for sensing
Unfortunately this isnt a diy forum

I’m tired of these mediocre “semi flammable” refrigerants. If we’re going to do it let’s do it right.
Unless we change direction we are likely to end up where we are going.

When asking for help, always provide the model number of the unit you are working on.

Not a diy at all. I work for a small company do more install/ fab and mostly air conditioning. heating wise almost everything i touch is gas hot air furnace . I understand flame rectification well with an independent flame sensing rod. I was hoping for some clarity on units that use the hot surface igniter to ignite the flame and sense the flame. i rarely ever see it so no experience. Ive had an account for a while but just read posts . this forum is just like every other one you come here for some friendly info/advice and everyone jumps down your throat. Somehow before i post you say i should get my post count up?
not working on anything in particular right now but ive seen a few of these in power vent boilers and always wondered how they work thanks

I mentioned that because we try to keep the more technical discussion on the locked side.
Unfortunately I don’t have anything to offer as far as diagnosing those flame sense systems as I have never seen one.

I just did a bunch of googling and I couldn’t find anything specific to those.
On “normal” furnaces with flame rods and ignitors I have never used a meter to diagnose the flame sensor. I verify it is clean, has good connections, doesn’t have a cracked insulator, is inserted in the flame correctly and that the burner is bonded to the board and if it doesn’t work with all of those issues eliminated it’s the board. For ignitors I check voltage and watch them glow and for some styles check the amp draw.

Sean – That’s a bit technical for the open forums. Get your post count up and post the question in the Pro only forums and we’ll get you some help.
