Thermistor Replacement

[Elembytes]

Well, I brought my camera down to take some pics of thethermistor replacement, but thanks to Long0 and his pics, that's about it and nothing more to show really. It was pretty straight forward.

I removed the plastic case that contains the fuse access door -- there were 2 scres adn 2 bolts. Then I removed the fuse box assembly which is 2 nuts. It came out, but it is pretty tight in there. Mine swung the opposite way of Long0's in his pictures. The thermistor was right there behind the box and quick-tied together with some of the wires. At this point I removed the green cover directly above the fuse box -- where the steering adjustement and ignition are located. This gave me a little more room to move the fuse box. I then cut out the thermistor, put new shrink wrap on the wires and soldered the new one in. Very straight forward.

It has been starting fine so far. I'm not sure if it is my ears or not, but the click of the solonoid seems to be a little louder, but that could just be me. Hopefully this licks the no start problem that has been frustrating as he11 for a few years now. Since it only did it occasionally, and of course always did it when in a hurry.

Hello: Wow--I have had my 4300 in for service and specifically told them that I had times when all it would do is crank and crank and never fire. All they told me was, it starts fine every time over here in the shop. Then told me it was ridiculous to start replacing things trying to find out what it is. So, it was brought back out to me. Last Friday it was doing it again. Once I get it started and use it for a while and shut it off, it fires really fast when I go to restart it. I ordered a thermistor after reading these posts. I don't know if I should pay big $$$ to have a John Deere mobile mechanic come and replace it for me or if I can do it. I am mechanically inclined but not good with electrical stuff. I am worried trying to get at this darn thing in the first place. I really wish someone could shoot a video and put it up on You Tube showing step by step process. I don't even know if the Deere tech manual explains how to fix this problem or not. Step by step instructions would be great. Just so nice to know so many others have had this same issue. Makes me wonder why John Deere mechanics can't research issues and fix things. I spent over $1,000 dollars servicing my 4300 this past fall. To ONLY have this issue still happening is very upsetting and frustrating. Thank you to all for your help this is so good! God Speed!
