The sanitize cycle has stopped working on this dishwasher. I’ve checked the continuity on the heating element and received 15 ohms resistance on a digital multimeter. The high heat thermostat is showing open on an analog multimeter. Any suggestions on what the problem might be.

The high heat thermostat is showing open on an analog multimeter.
This is probably your problem it should be closed.
The description says it is resettable (Item 29 in Section 3) often this is a little shaft that pops out between the connectors at the back. If this is the case just push it back in and you should be good to go.
There’s nothing sticking out of the back of it or anywhere else for that matter. So a replacement part is in order? Also one of the connectors is showing some burnt area, however it still fits tightly and is not burned thru. Would this have occurred whenever the switch stopped working?
It could. If the contacts became pitted/dirty as the thermostat failed they would heat up as current was passed through them.
Before hooking up the new thermostat clean the wire’s connectors as best as you can, a small file or some fine emery/sandpaper will help here.
just to make sure we’re talking about the same thing the thermostat, when hooked up to my multi meter shows 0, the same as it does when I touch the prongs together. Does this mean the thermo is good or bad?
0 ohms means that it is good and it should pass current.
Here is the tech sheet for this unit.

Does the unit dry the dishes if it does then the hi-limit thermostat and the heater and the wires from the control board are OK.
so the high heat thermo is alright. . . I’m going to retest the heating element with the current analog multimeter and I should get a 0 ohm reading if it’s good, correct?
No it has not been drying the dishes properly and I really appreciate the help. I’m going to clean the connection on the thermo as best I can and reinstall it. . .

I’ve checked the heating element in the bottom of the tub and it still reads 15 on my analog so I’m assuming it’s alright as well. I’m open for any futher suggestions. The sanitize light on the button comes on, but it doesn’t high heat dry and the sanitize light on the display which used to show under the “Clean” light upon completion of cycle still does not come on.
It sounds like the control board is toast.
The usual way to troubleshoot this is to check the keypad and if it is good then replace the control board. Still a bit of a crap shoot but your odds are better. Unfortunately Frigidaire does not give the pin-outs for the keypad so you cannot really check it but your symptoms sound more like the control board is just not sending power to the heater.

Is there anyway to check the control board or is it just a crap shoot or process of elmination?
Process of elimination works
Or
You can force a heating cycle (see the tech sheet) and measure to see if the board is supplying power to the heater/thermostat combo.
Okay, replaced the control board and the washer lit up, but no sound of water running as was usual. After about 2-3 minutes it started running cycle, still without the water sounds. It ran a full cycle on pots and pans with the “sanitize” led on. High heat dry worked and hot moist air could be felt through the vent. Upon completion of cycle only the “clean” light was lit. Upon opening the dishwasher the bottom of the tub still contains 1-2 inches of water. Removed dishes and ran another cycle with same result.
Wife is talking about getting a new dishwasher or home handy man. . . Suggestions???
Check that the overflow switch is activated.
Sometimes the float can get stuck in the up position.

Yea, well it also drains better if you knock the plug out of the new sink disposal unit you just installed too. Ran another cycle and the heat dry seemed to work, but still no sanitize light at the end of it.
I have a Bosch dishwasher and I can’t get the sanitizer light to come on. Does that mean it will not sanitize my dishes
