Suburban electric water heater not heating
I traced the electrical problem with the heater down to the lower of two high temp limit switches. It has failed in the open position. The voltage has to pass through this switch,then the upper one b...

YES this is a safety issue!!!!!
You state lower of two high temp so at least you understand that you have 2 different temps of t-stats
Left set of t-stats is for the electric heat element.......it is a 120V AC set with normal temp t-stat and a high temp t-stat.
Normal t-stat is what does ALL the heating control. OPENS when water temp reaches 130*F then when water temp drops below 115*F it CLOSES and allows heating to occur with electric element.
The High temp t-stat is there to shut down heating if normal t-stat FAILS. It is a 'safety' backup measure. It OPENS at 170*F and TRIPS so that no more heating can occur until owner intercedes.
BUY a new 120V AC t-stat set. $25
FYI the other set on right has nothing to do with electric heat function.
It is a 12V DC set for control of propane function. Same set up, same temp set points....Just 12V DC & for propane.
IF either of the High Temp t-stats should FAIL to OPEN (after normal has failed) then the only thing left is the T&P Relief Valve which OPENS (and BLOWS Steam/HOT-HOT water out side of Water Heater OPENS at 210*F/150 PSI
REPLACE THAT 120V AC Set and be safe...water heater although small is a BOILER capable of severe injuries and damage.

Replace it!
Use PROPANE until you replace the electric element set of t-stats
