John Deere Original Equipment Electronic Control Unit #AM141075

It’s expensive. But, an OEM I feel is the only way to go. It’s not difficult to replace. The difficult part is trying to be almost certain it will help solve a nagging problem that apparently is common to the John Deere X500 garden tractor. I am confident.I want to compliment the seller for taking the time to properly packaging a sensitive device. It’s refreshing and increasingly rare that someone took the time to properly protect the device for shipping. Far too many shippers these days don’t do that. It’s a shame. Thank you.After running my JD X500 twice as long and in 80 degree temperatures my tractor never even had a hiccup after replacing the ECM with the OEM. First time in the two years it’s been failing. Bottom line is this product fixed my tractor. It’s no longer stalling. The JD dealership failed twice diagnosing the cause. They kept telling me they ran it for periods of time. But when I pressed the service manager he wasn’t the one working on it. He was relying on some so called mechanic. But, I do have a life long knowledge of electronics as I did teach it for 31 years after my electronics education from high school and the USAF.Don’t know what qualifies a JD technician, but like so many other companies the AF has much higher standards. Go figure DEI…maybe.I highly recommend anyone experiencing this problem to purchase the OEM John Deere ECM. Pay the extra money and save yourself money, time and frustration because this problem seems to be common to the X500 and similar JD series models.

Deere X320 mower (11 years old) quit while mowing. Would not restart. Checked battery voltage, way low. Disconnected the battery and connected it to a battery charger. Noticed positive cable connection was corroded on mower. Battery would not take charge. Replaced battery and positive cable. Cranked better than ever but still wouldn't start. Checked plugs, wet with gas. Dried off and cleaned plugs. Still, neither plug was sparking. After a few checks of the wiring, etc suspected this module might be the culprit. Called dealer and asked if I could bring it in and see if their shop "test" module (the same part they keep around for diagnosis, as there is no way to check the part itself) could be plugged in to the mower to check if the existing module was the cause. No dice, too busy to give me 5 minutes of their time. Note, the same dealer suggested this trial "fix" the last time I had similar issue (about 5 years ago) and I brought mower in, and the trial module solved the problem, and they sold me a $75 part. Not this time. Maybe a different service manager. $100 gamble paid off. After installing the replacement module the mower started right up and it seems to run fine now. The part was delivered 2 days ahead of original estimate. It was fulfilled by another "local" dealer, slightly further away than the "no dice" dealer. Maybe I'll call them next time instead.

This fixed my JD X300R Lawn Tractor.I bought my mower new in 2010. Last year, and this summer, my machine started to turn itself off in the middle of mowing. It acted just like I turned the key off. It would always restart and then run long enough for me to finish my lawn. I replaced the ECU with this and have used the mower 5 times since. This part has fixed the problem.This IS a John Deere part. It came in JD (sealed) packaging (see picture). It is the newest version of the part. My part is dated 6/19/16. It screws right in - under the dash.I don't see how charging the battery "wrong" could cause this part to fail. Instead, I believe when the battery is getting old, and the mower won't start, that is what's taking these ECU's out. I've seen the same situation with some car parts. We turn the key on, the ECU needs the full 12 volts to operate properly, the battery is weak and as we try to start the machine - the voltage drops to a much lower voltage. The ECU gets a much lower voltage - and something internally goes awry. In hindsight: The first time I had this "turn off" problem, was soon after it wouldn't start last year due to a worn out battery. From now on, I will make a note in my cell phone calendar to replace my battery automatically after "x" years, so I change it before it ever gets weak or fails. This part cost me $57. A new battery only cost me $33.

Was worried about buying one of the Chinese knock-offs. Spent a little extra and all the problems were instantly resolved. Mower would shut off while mowing and not restart until it cooled down. This fixed it.

My x320 had fuel, spark but would simply not fire and run. This happened right after my OEM battery died and as I was cranking the old weak battery, I cranked until I could here the click click click of the starter . Appearantly this alone was the cause of the Interlock Control Module going bad. I DID NOT charge the battery while connected to the mower. I have never tried to "jump' my mower batter. Did not, nor ever have. I guess the battery being as low as it was and attempting to start it with such a weak battery was enough to shorten this part out.My local JD service tech told me that the X series mowers had at least 7 different variations of this ICM in the first few years. This told told him that they didn't have it right when the mowers first came out. My ICM was from 2009 so I probably had one of the early "bad ones". My local dealer wanted $79.00 plus tax. I got it here $22.00 cheaper and no tax. Sorry local dealer. Plus shipping was super fast. Got it days ahead of schedule.Lastly, this part had a manufacturing date of May 2015 which told me that it was the latest and greatest improvement of this part. No New Old Stock here.
