John Deere 3720 CAB/TLB, JD455
If you own a 4x00 series machine, you really should have one of these in the parts bin!

This Thermistor is used in the John Deere 4200, 4300, 4400, 4500, 4600, and 4700 series tractors in the fuel solenoid circuit. If your machine will crank but not start, the Thermistor is the most likely cause. Search the popular forums (GTT and TBN) for lots of reading!

This is an exact OEM LUV10323 replacement, but at less than 50% of the John Deere price.

This part is most often found soldered in the wiring harness behind the fuse panel, and very difficult to replace. We have made this job much easier with our new QuickWire kit that include pigtails and heat shrink solder sleeves.

Believe I found where mine is located in my JD 4300. Just to the left side of the fuse panel protruding out of a wiring harness.
