I swapped out a dead control board on my Hobart LX18C dishwasher, but apparently they come pre-programmed to the high-temp version. How can I re-program the board to the low-temp sanitizer settings?

I have to asume the wiring connections had not changed since it last worked.
There are three versions. LX18, LX18C and LX18H.
Inspect the relay board for damage. The connections can come loose and melt relays.
It could also be the wash sump tank heater or the booster heater if it's an H. The other two only have a sump heater. If you power it on, and have no water in it's tanks, the elements can glow red hot till they trip the high limits.
Depends on the version of the control board. If its the original, with a large heat sink near the center you can only adjust the rinse lenght by adding a jumper. Look on the right side near the middle to top. you will see a place to add the jumper in a set of pins, near where the jumper is for low or high temp options.
If it's the new style, you can short the two pins and go into factory service mode. Use the buttons on the board to advance through the options while monitoring the display. the Up arrow will incriment through each option. Powering off will save the changes.
A hobart LXIH-3 uses a chemical to sanitize however a 120 degree wash temp is required as well.
Turn up your hot water tank that supplies the dishmachine, make sure your sanitizer is pumping into the rinse cycle using micro-clorine test papers and all is well.
