My GE 40 gal electric hot water tank (actually made by Rheems) is tripping
the high temperature limit safety switch. I suspect that one of the two
thermostats has its contacts welded together. The manual that came with it
shows me how to change the heating elements, but not the thermostats. I
can't readily see how they unfasten. Anyone else done this?
The manual shows an exploded view, and gives me the part number for
them, but the diagram is too poor quality to help.
The unit is little over 5 years old, but had a 9 yr warranty. I live
out in the boondocks, and there are no service people close. I installed it
Those thermostats are usually held with spring clips which keep their
sensing portions snug against the tank shell.
Look at them and you'll see how to spread the clips to release them.
If they are the usual "standard" size and shape, replacements are
available at Home Cheepo and Lowes, among others.
Thanks, that is the kind of info I needed. I was particularly wondering
about how to remove the top thermostat which is right up against the
high-temp limit unit. If it slides down, then that will do it. I'll try it
Thanks to everyone who responded.
Literally had to do this same thing this weekend.
Turn the power off. If its the bottom stat, you remove the two wires leading
to it, and slide the stat up, and off the clips.
Top, normally you remove the reset, and the upper stat slides up as well.
Make sure its the stats, I had a combination issue, a burned out lower stat
and a burned out lower element.
Thanks. Actually, we had to have hot water(per the wife), so I went out and
bought a cheap new one and replaced it. I have time to play around with the
old one. When I have it fixed and the new one goes out I will put it back
again. Fortunately it takes only about a hour to change, mostly waiting for
the tank to drain. Since I did it only 5+ years ago and used flex pipe for
all connections, the piping comes off easy.
I already checked the continuity on the heating elements, and they seem
to be ok. Just have to figure out if the thermostats slide up or slide
down. They sure did not leave you much room to manouver. Didn't have time
today to look at them -- will have to wait till this weekend, I guess.
