What does all this gubbins do?

[waddycall]

my Henry Hoover packed up on Friday. I need it for work so had a look just now to see if I could find the fault. This little board is connected to the high/low speed switch. I’ve removed it for now and connected the motor direct to the double pole on off switch and it’s now working. Anyone know what this board does or how it works. Seems a lot of stuff just to slow down a motor.

That board is why a lot get chucked out.

No point replacing it, the replacements are made in China, and last about 3 months.

Current regulator to slow motor down.

Wigglies go in fast.
Wigglie go out slower.
Wigglies give up heat. As a present.
Heat make wiggly thing sad.
Sad wiggly thing no longer wants to slow wiglies down.

Looks like a Triac comtroller. As said bin it.

Wigglies get chopped up so as not to get hot

Its the bit on newer henry models so they can still sell them in the EU isn't it? i "think" they had to make them more Eco so they could continue selling them. Bit like DEF on cars lol

I could be wrong though!
