Need some double check on a planned repair, please.
I have a dishwasher with failed repair by a service company. Symptom was the timer would not advance past 7 o'clock or 10 o'clock on high temp wash or rinse setting. Serviceman replaced the (1) timer and (2) thermostats to no positive effect, just $200+ bill. I got the tech manual, and saw the likely culprit was the high temp sensor.
I removed the sensor and determined a contact rivet was bad/loose and sensor was always 'open'. I put the sensor back. When I pulled it today to get the part number, the wire connector (white) on one side was burned onto the contact. Before I replace the sensor I want to know:
1) is the wiring to the sensor direction specific (one white, one blue)? 2) is there something else here?
thanks
Dishwasher works on low temp cycle Dishes never get dry Running on High Temp Cycles leads to timer getting stuck

The model number you posted does not come up. Verify and repost it.

In order to find the correct wiring diagram we need the correct and complete model number. You can try to search for the wiring diagram inside the door, the control panel or the toe panel.

Gene, thanks for your patience. I cannot get the correct Model Number as its rubbed off the sticker, but the wiring diagram that came with the unit is P/N 154457601.
Frigidaire UltraQuiet III dishwasher, 700 series assumed from the model number ending 750RCC1. Under the frigidaire logo on the wiring diagram is a number 030108, but I don't think that is really useful.
Red wires go to the hi limit thermostat. One blue connector, one White connector.

Quote:...is the wiring to the sensor direction specific (one white, one blue)... No, there is no polarity on such parts. I found the Tech sheet with the wiring diagram but there is no any temperature sensors shown. Looks like the complete model number is Model FDB750RCC1

thanks, Gene. Appreciate the full model number for future reference.
Curious comment about the hi-limit sensor, or lack thereof. I bought a replacement, installed it (yes, there was one there). The dishwasher now works properly on all (heating) cycles again. Success!
Lesson to others-when your dishwasher works on cool cycles but not hot cycles and the timer won't advance, try the $20 hi-limit sensor first!
