POWER CORD

INTRO:                  In this episode of DeWalt miter saw repairs, we’ll be looking at the power cord.

                If your saw is having power issues, it can be difficult at first to determine exactly where the problem is coming from.

                So first we’ll help you diagnose a power cord issue, then we’ll open this saw up and show you how a replacement is done.

DIAGNOSE:         When a saw is having power issues there are 3 things that could likely be causing it. The power cord, the power switch, or the carbon brushes.

                To narrow your problem down to the power cord lets look at some symptoms of each component.

POWER SWITCH:             A failing power switch usually causes problems at start up. If it takes several attempts to get the saw to start, but once started keeps running just fine, it could be your switch. For more information on diagnosing a bad switch, refer to our video titled “DeWalt Miter Saw – How and When to Replace the Power Switch”.

CARBON BRUSHES:         Carbon brushes are another common power issue culprit. These wear down over time and so are one of the most commonly replaced power tool parts. If your saw is getting intermittent power – that is it stops and starts during use. And if banging or jostling the tool helps restore power, check out our videos titled “DeWalt Miter Saw – How and When to Replace Brushes” for more information on diagnosing bad brushes.

POWER CORD:                  If you’re still with me then you’re probably thinking you’ve got a bad power cord. Maybe your cord has obvious signs of damage. A cord with any exposed or frayed wiring should be replaced IMMEDIATELY! Maybe you cut thru it while you were sawing – Hey, it happens!

                And if the cord looks fine, but wiggling it around corrects a power issue, there could also be a short in the cord you can’t see. Sometimes the best way to know for sure will be ruling out the other options first.

                Luckily, cords aren’t too expensive. And you don’t need to be an electrician to replace one yourself. If you’re ready to take on the challenge, grab your parts and follow me!

HOW-TO:            Replacing the cord requires three parts. A new cord (obviously…) and two terminal connectors, one female and one male. I’m using OEM DeWalt parts from mmtoolparts.com, that way I know the length of cord, gauge of wire and materials used are all in spec and won’t burn out the motor or cause electrical issues down the road.

                The cord wires directly into the switch, so first we’re going to open up this handle assembly using t20, 25 and 30 torx bits.

CLOSING:            When your saw is having power issues, it can be frustrating isolating the cause. Hopefully this guide helps you diagnose and correct the problem quickly, so you can get back to what matters.
