I had an issue where my water heater kept shutting off/pilot

I had an issue where my water heater kept shutting off/pilot went out. It's an AO Smith with a sealed combustion chamber. A technician came out and changed the thermocouple but it required the full assembly, due to the design. A week later, the problem recurred. I called another plumber out and he removed the seal and ignitor and we have to light it manually now but he says it should stay lit from now on. Is there any safety concern?JA: OK.

Pearl, I'm fairly sure I've got a bad thermocouple on an

Hi Pearl, I'm fairly sure I've got a bad thermocouple on an AO Smith water heater. The pilot lights just fine, but goes out as soon as I release the button. I bought a universal replacement thermocouple, but now that I've pulled the burner assembly out, I see that the original has a little resistor or diode built into it. The universal replacement does not have this. Do you know what the purpose of that diode is? Is it safe to install the new thermocouple that does not have one?JA: Sometimes plumbing issues that that you think will be really complicated end up being easy to fix.
