Wahl Foot Massager Repair
My friend bought this foot massager at a garage sale/yard sale. Model # is as in picture.
The power socket will take a figure 8 mains plug which is a design fault in my book. My friend plugged it into 240 mains and it went bang.
It actually runs on 24v so he ordered 24v supply from e-bay. He gave it to me pulled apart (something techies shiver at)
so I got down to the business of checking components. The WFP70n06 (Mosfets) were both dead and one of the diodes under them was blown apart as seen in the next picture.
So I went to see if I could get these mosfets from my supplier and he informed me he had nothing at 60v 70A. I did email a service agent here in Australia and he informed me he doesn’t carry those parts.
Wahl is mainly known for hair clippers etc so he only had parts for those, I then emailed Wahl Australia and got no reply. So I got on the internet and got some data sheets to compare.
I found one that compared favourly.
I ordered 2 from Digikey and they only took a week to get here from the USA. I also swaped the FR107’s for 1N4007.
I forgot to take a photo of the new components on the board, but it was successful and worked as new.
