On a hot day the saw just stopped working. would not and has not turned on

Hello Derek, it seems that your motor or motor brushes have failed please contact the manufacture about replacing the motor brushes.

The blade may have stretched to the point where it can't be adjusted anymore. Blades get hot even going thru wood. Usually when this happens it happens in a way that puzzles you. You can try to tighten, but you may find it's time for a new blade. GOOD LUCK FRIEND.

Anon, sadly to say it sounds like the motor is coming to its last days. The motor spindle is shot and when it gets hot it is expanding and locking shut.

Once the saw cools down will it restart and run fine? There are a couple other solutions that are not directly due to carburation. The first two solutions above are definitely your first options.

1. Ignition Coil: Highly unlikely, but possible. I seen some where they get hot and run fine while cutting, you shut it down for a few minutes for whatever reason and it won't restart or starts and stalls.

2. Crankcase Air Leak: We started to see more and more of these issues. There are a couple of quick ways to test this if you do not want to pay a shop to do an actual test. You want to do a cold test and a hot test. With a half tank of fuel, start the saw up for the first time of the day. While the saw is idling, turn the saw sideways from right to left, do this slowly, listen to the saw idle, if the speed changes by increasing or almost stalling, you have a crankcase air leak. Most bad air leaks won't be noticeable until the saw has gotten hot and the aluminum crankcase starts to expand a bit. Do the same thing once the saw has gotten hot. If this happens when it's hot, chances are that it won't start or starts and stalls until it cools down and everything retracts.
Test Results:
Sporadic idling when cold: Most likely just the oil seals, fairly inexpensive repair.
Sporadic idling when hot: Most likely crankcase itself is leaking, requires a complete crankcase gasket replacement. Can be fairly expensive to repair.

I would have checked the cord first. Cords are a high failure part because they always get bent and pulled and such. Some versions of the jr3000v had problems with field wires breaking right at the field terminal.

The motor has a component called a clixon (there are other names for it, too). The clixon has a step up coil and a capacitor that gives the motor an extra bit of juice to get started turning. When it fails, you get the kind of thing you're talking about. If you keep trying to use it without this component working, it overheats the windings and shorts the motor out, killing it. You're most likely going to end up replacing the motor now.

Sorry I didn't have better news for you.

Hello vince....sorry to be the messenger but it sounds like your saw's motor is shot. You can purchase a rebuilt from dewalt. Joe

Hi,
The switch went bad.... the switch was hot when you were working it and then you set it down, it cooled off and now the switch will not contact....
Replace the switch...

The red you saw , was the defrost heater , defrosting the coils . When you disconnected the power and then reconnected, it was still in the defrost cycle . A defrost cycle lasts 28-32 min . For example , if it was in cycle for 20 min and you unplugged , whenever you reconnected power , it still had 8 min more before it will turn on . Plug in refrig , and in a little while it WILL turn back on .
