Well I'm scratching my head. Saturday I went out and plugged in the block heater as its been -13°C (8.6°F) for a daytime high! It was plugged in for about 1 1/2 hrs. Company showed up so no tractor work that day. I went out and unplugged it. Sunday I again went out plugged it in and nothing. No sizzling, I left it plugged in and like I usually do I went out to the barn an hour later and felt the engine block, it was cold! The tractor will be three years old in March and I have never plugged it in and left it. 1-1.5 hrs is tops for plugging it in. I put my old analogue metre on each end of the plug and it shows resistance so the plug is good. Now I put the meter on the two prongs of the heater and again it sweeps the needle a little bit. I'm not up on this stuff but I remember checking an oven element that way and the burnt out one showed nothing and the new one would move the needle. So here I am! Are they prone to burning out? Thanks for any info.

Block heaters do let go as they are simple heating elements. They are subject to heat cycles and vibration damage.

What does your meter read if you put it on the terminals and set for ohms?

Would not a heat gun set on low blowing at the bottom of the engine for about a half hour do the trick.

Goal is to make oil flow easier in the cold.

I put my digital multi meter on it and it shows nothing. Put the alarm on the meter and again nothing. Like I said I am not up on the use of multi meters. But I think it's done for. I have one ordered from Parts For Trucks. They cross referenced the JD # and the one they found looks the same in the pic and is 400 watts. With a 3/4" pipe thread @ $51 VS JD's $128 CDN. Time will tell if it's the same.

You should read approximately 36 ohms with your meter set to "Resistance". It will vary from heater to heater a little bit. If you are seeing an open circuit, the heater is bad. Make sure you measure on the terminals of the heater itself (with the cord unplugged). This way you rule out a broken wire or other fault in the cord.

Do you always unplug the heater before starting? Starting the engine while they are plugged in seems to kill them quick,

We went through this at work years ago. Guys were starting their trucks while still plugged in and burning out the block heaters. With this example they were Mack trucks and the block heater was up high above the water pump. When you started the truck there would be a momentary lack of coolant at the heater which burned it out instantly.

The block heater on these tractors is down low, but after learning what I did I always unplug equipment before starting it. I don’t know if the same thing can happen with the position of the heater on these tractors buy why take a chance?

Well to follow up I got a new blockheater and installed. Got it at a local company Parts For Trucks. $ 42.50 vs JD $128.00. Sorry JD but that's too much of a difference!! It was a Zero Start and I used the cord that came with the first one as the new cord is way too long. I had the thread dope from when I did my rear hydraulic setup. But used teflon tape as well as per some of what I read on here and no leaks :) I didn't bother with the drain in the block, just drained the radiator and took out the old heater replaced with the new one and filled up the rad with fresh coolant and good to go. I used the tractor a few hours before using the new blockheater to make sure no air was trapped in the area. I went a little further and bought a couple Wi Fi plugs as seen in the picture. Wednesday my day off I awoke to a good amount of snow to clear so with my new phone App I turned on the plug in my building and noted the time. After breakfast out I went, 30 mins later. Turned off the plug and unplugged the extension cord, put up the door and cleaned the area of snow. I felt that was enough time to cool the element before starting. And away it went. Just like starting in summer. I love the ability to remotely start the blockheater when I leave work and 30 mins later when I arrive home. The tractor is ready to start. Perfect. Thanks to the guys that posted on here about their remote Wi Fi plugs. And their processes on changing their failed blockheater. :bigthumb:
