Wahl 8685 shaver repair
Hi all,
For posterity, here's a problem we had with our Wahl 8685 ("Peanut") shaver / trimmer, and how I fixed it. It's a few years old and we use it for all our haircutting. My son was using it the other night and he said it started sparking, whereby he unplugged it. I had a look inside and found that the design is fairly simple - a small DC motor, a bridge rectifier, and a resistor. The resistor appears to act as both a fuse and a small voltage-drop for the rectifier. I don't know why it decided to give up the ghost, but the resistor was intact enough to read it as either a red-green-red (1.5K ohm) or a brown-green-brown (150 ohm) - I hate off-color resistors! I put in a 1/2-watt 1.5K ohm resistor and the motor worked fine, but it didn't have enough strength to power the blade assembly. I thought it may also have been because the motor was failing, but I gritted my teeth and put in a 1/2-watt 150 ohm resistor, and the shaver is back in the land of the living. I thought that someone, somewhere might be able to use this info in case their resistor also blows but has an illegible value for determining replacement. |

One thing that you might want to keep in mind is that the cutter blades on all clippers need lubrication. It's just possible that yours need some and that the extra load from the extra friction caused this resistor to burn up. These clippers always come with a small tube of light oil, and you need to use some of it occasionally. - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |
