|Thread: Warco WM250v VFD. Start problem.|
Doesn't look like a lot of interest, but I promised....
Replaced switch and all good. Only thing was, as soon as I unplugged the wires from the original switch it became immediately apparent the fifth wire (the solenoid drive wire) had NEVER been attached to its slip-on connector plug, never crimped, just loosely sitting in the plug, so for thirteen years, this had just been on the cusp of working.
Old switch was fine after all.
No worries, one of those things.
I have a 2007 WM250 which has just gone wrong this weekend. If I press the ON button, the motor turns on, and speed control works too, but if I release the button, it will not remain latched on. I unbolted the front panel,so the button panel was loose in my hand, and tried this again. I notice the KEDU KJD17B NVR (no volts release) switch buzzes when I press ON in a rather loud and unusual manner. It certainly is not latching either. This switch is a 5 pin switch which is readily available on Amazon for about £18. I have ordered one for next week.
Of course, the 5th pin is provided a latching mains signal and this comes via all the interlocks etc, but the fact it buzzes so much must mean there is power to the solenoid, and yet it still is not latching, so I suspect the switch is failed internally.
I will happily report back when I get the replacement fitted. I hope that may be of interest to other owners.
