Hi there i have a makita HR2470 and last week i was chasing out a wall and it just stopped mid chase,i checked the transformer it was connected too that was fine,then i've checked the lead at both ends all o.k,so i then checked i had 110 volts power at the drill switch and the other side of switch all o.k so i ordered new brushes,fitted them and cleaned armature and it still dosen't work the fan dosen't spin or anything as if no power,any advice on what to try next would be much appreciated,many thanks.

check voltage from transformer when it cuts out to board if voltage ok bad board if no voltage bad transformer

1 week may not be enough time to hear back from a national bank. you can always contact the person that assisted you and ask them to check the status of our credit card adn they usually do this without being asked.

Rebuild the machine, when you get to the last piece the lever. Put the lever in the hole pointing to 2 o'clock then applying a little pressure rotate the lever anticlockwise and when it gets to the 7 / 8 o'clock position it should press fully into place. Turn clockwise and it will lock into position.

Hi Marty,here's a link to your P0300 code.

ask your "local garage" to get off their lazy butts and chase the problem down with a test light or volt meter. were the voltage stops is where the problem is. provided the linkage is in working order the only way to fix this is the chase it down as such. it could be anything from a faulty ground connection to a corroded section of wiring to a faulted terminal connection

There should be a "mini-manual" (tech sheet) hidden inside the unit
behind the control panel or hidden on the left side behind the grille, which is
very helpful when troubleshooting, testing, and locating components.



It *may* have the part number of the low voltage transformer, possibly on a loose sheet inside the mini manual.

Otherwise, you can find links to helpful exploded view diagrams and part ordering help here.

I recommend that you bookmark that link to your favorites.

There should be a part number on the label of low voltage transformer.

The GE part number will be something like WB##x##### and the Samsung number will be something like DE_#######.

The Samsung part number is almost always cheaper.

Feel free to contact me directly if you need more help.

if the system continues to show this error after the case has been closed correctly, then check the connection inside the case.....if good then enter bios at startup and turn the feature off and the message will stop.
