Good morning and happy Easter!
Just a quick question on your opinion about changing the diode. Basically, at this point is it worth it?
The heater (40 gal.) Is about 15 years old. It was here when we moved in. I replaced the pilot light assembly six months ago and other than that, it's been working normally. I know it's well past it's expected life at this point.
I bought a new magnesium diode and figured it wouldn't hurt to change it. But, I'm getting cold feet because the old one won't budge. I'm afraid of breaking something and rendering the threads ruined and left with a useless heater.
Given it's age, would you ride it out orgo ahead and try to replace the diode?
