Discussion for the DeWALT DW911 Type 2 Cordless Job Site Radio
I don't see a parts diagram for a Dewalt DW11. So I will give you two choices of antennas for two different Dewalt radio model numbers. If it is a DW911 the part for the antenna is 429790-57. If your Dewalt radio is a model number DC011, the part number for the antenna is 5140019-28.
My radio just stopped working checked this site and used your comments to get it apart. Worked great. Replaced fuse, plugged in and lights came on. Put it backed together, did not work, fuse blown. Opened unit, replaced fuse, powered up unit, worked again. Again when I placed front back on fuse blown again. Where to look for problem and answer? Please help.
Usually when a fuse blows as many times as yours has. It would indicate that there is a another electrical problem causing it to blow. For example transformer, PCB board,could be a number of things. Try taking it to Factory Owned Dewalt Service Center. They have a max repair rate on that model for $74.00
My dw911 will only work with a battery, it will not work with the AC cord. I read a short across the yellow leads of the transformer, does this mean the transformer is no good? Both fuses are okay, no cold solders..no burnt components. Power cord is good to the circuit board. Thank you
I contacted the manufacture today regarding the delivery date on the part number, 429790-53 hardware bag. Unfortunately they cannot give a delivery date of when they will have this item available to ship. We have checked with other service centers around the country in the attempt to locate this, but we are not having any luck. As soon as we receive this item be rest assured it will be shipped to you.
There are a couple of fuses inside your radio. Items #31 and 32, part numbers 5140019-09 and 429790-32. Sometimes these fuses will go bad. Of course a blown fuse can be a signal of a bigger problem as well. Replace the fuses. If the fuse blows again then your radio likely has a problem with one of the circuit boards.
A loose neutral in power source sent voltage to neutral side of plug. What would that have damaged in my DW911 radio and how could I test it to know that is the only problem it caused? The power company fixed the problem and this radio is the only thing that was damaged.
The symptom: Plays on battery but not on AC plugged in.
The failure was the printed circuit trace between the point where the power cord enters the circuit board and the second point where it feeds the power transformer.
The copper traces had vaporized. Both legs. They were totally missing.
The paths had the appearance of overheating.
Fix was to solder jumper wires between the 2 points (2 places)
When charging batteries the current between these 2 points must have exceeded the capacity of the trace to handle the load.
I like to connect my mp3 player though the aux port... I already tried multiple aux wire connectors and came to realize that the aux on my DW911 is malfunctioning; some sort of shortage. Any suggestions?
My radio won't charge the batteries although the light on the radio flashes showing it's charging. It then shows that the battery is charged but the battery is less than 1/4 charged. The same battery inserted in a good charger works fine.
How do you access the fuses and replace them? I have managed to open the radio without damaging it any further, other than a few screwdriver marks in the seam.
It was given to me and upon plugging it in, it does nothing. No lights or anything else.
Appreciate any information you may provide
The Type number will be listed on the same tag as the model and serial numbers. If the antenna is the only part in question it looks like it is the same on either the Type 1 or 2. The antenna is part #429790-56 and is available from http://www.ereplacementparts.com.
Most likely the fuse was blown upon plugging in the unit.
Sometimes a sudden voltage spike will occur upon plugging in the ac cord and blow the fuse, sometimes it happens so quick the unit appears to have been dead all along. The fuse used in this unit is only 1 amp and will tend to blow quite easily. I've seen many fuses blow due to the radio being plugged into an extension cord that was also supplying power to a circular saw or similar, the sudden power drop and spike when the saw is started and stopped is enough to pop the fuse. Hope this helps you
I Had the same problem and it was the 1 amp fuse on the pcb board next to the transformer. At first glance the fuse appeared good, but a quick test for continuity showed that it was in fact no good.
The same thing has happened to mine twice. Although the fuse looked good, it was bad. Temporarily bridge the fuse holder and the radio will come on. I replaced the 1A fuse both times and it works great again. When ordering a replacement fuse, order a few extras, they're cheap.
The newest model radio has 2 small screws in the back next to the bottom handle. I almost broke my radio before I figured it out.

I had this same problem. For cosmetic reasons, pry open the bottom seam about 4 inches in on each side. Use two screwdrivers one to hold open position and the other to work your way down the seam. Once you get the bottom---the sides and top will fall open. Then unplug the two small multi-plugs to separate the front completely. I had some major pry marks on the bottom to finally get mine open. Not a real good design for separation. They should have put separation slots with arrows to "PRY HERE". Once you get it open, you will see and understand the guides and snap locks they connect with. I marked mine with a black marker. The fuse will not appear to be blown but it is. Check with ohm meter to prove. Good luck. Gator Joe. Ocala, Forest

I had to open the case, I found this to work well. I removed all 8 screws, and put 4 back in but only slightly tightened to get the screw about 2-3 threads in. I placed the Phillips screw driver in the screw head and popped the top of the screw driver with a rubber mallet, rotating around the radio. That seemed to break the seal and the front popped off without and pry marks. Good luck. (Like the guy above I plugged mine into 220v, seems to have fried the transformer - I hope. Glad I could find one on this site).

I did as Phil did in Response #4: Took all eight screws out, then replaced two long screws in each end, backing them out 2 complete turns each; then took rubber mallet and long phillips screwdriver and tapped firmly on each screw 2-3 times. Front popped off and no unsightly pry marks marks on seam.
I picked up a used DW911 worksite radio/charger with a missing antenna,
I've been told this happens a lot with these units, has anyone replced one
of these parts (part #429790-56) and do you have any tips?
I have the older model DW911 radio/charger. I tried to remove the front case cover on the radio after removing the 8 screws but front cover will not come off case? any suggestions on removing, seems like it's glued on
This charger is a older version the pcb board use to blow fuses about once a week , now when I was using it last just listing to the radio it stopped . I checked the fus and it was blown again I replaced the fuse and still nothing . I checked the voltage on the board and it was zero . I ordered a new PCB board accordind to the model # , when I recieved it I noticed it was different. The new on is missing wires going from B+ AND B- going to the battery location also wires from A1 AND A2 going to the transformer. Do I have to un soder the wires from the old board and put them on the new one. Any info on this subject will be helpful. THANKS,
You do have to unsolder the wires from the old board and solder to the new board..be sure and not to get too hot as it will damage the board...:o
hope this helps..

I am trying to put the PCB board back in the charger the soldering went ok. My problem is the 4 WIRES that go to =AC5 AC6 CH- CH+ I don' t know where the go ,the wires colors are white brown black blue. I should have taken a picture of the wires before I took them off, any help with this problem sounds easy if I can find a picture of this but I can not find any. THANKS , ANDY
