What are you lighting? Furnace?

It sounds like a thermo coupling--Get the name of the unit and let us know---

If it's the thermo coupling--they are easily replaceable and available at a local store.

Hello there. I'm not too familiar with water heaters and although they are a simple creature compared to furnaces it appears that Lochinvar is known to have continuous troubles. Hope this helps.

Is it an older unit that you light with a match or a sealed unit that must be lite by pushing a chicker button??

Just as with a furnace, the flame has to be "sensed" for the unit to stay lit. My guess would be that there is a problem there.

Good luck.

"A PILOT light should burn for many seconds prior to shutting down if the flam sensor fails to detect flame... a main burner should go off within a second or two of flame failure."

Thanks for the moving assist Mike.

My hot water heater is the kind where I must light it with a match, or candle lighter which is what i use.

I turn the knob to "pilot", light the pilot and then hold the button down for at least a minute.

O.K.--that's repairable by a normal human (unlike the newer ones)

The thermo coupling is a thin copper tube coming out of the bottom of the control box and going down into the burner--the tip of the unit is just above the pilot burner---and is covered by the flame of the pilot when it is lit--

Go look and tell me if you can identify it.

Thanks Mike.

Watched the video.
Removed the thermo couple.
Will pick up replacement in the morning.

Hoping that installation will be as easy as removal.

Thank you so much for your help.
