Smelly Kenwood Chef A901
This Kenwood Chef developed a nasty little problem. The failure smelled expensive and the Chef even puffed out some smoke when it began to fail, it would operate, but noisily and badly, so it to the workshop it had to go.
It was in decent overall condition and has loads of accessories, so definitely worth saving since a new one is over £300 new.
Since the speed control circuitry is a common failure on models of this age, it seemed sensible to start there. On this unit, access wasn’t a problem and the issue was quickly diagnosed. Both capacitors had failed (spectacularly) and one of the resistors had become weak by about 20 Ohms or so. Repair kits are readily available online for those who are willing to save these excellent machines, so after removing the faulty components, new items were fitted.
Another little annoying problem with the Chef, was the main drive belt. It was intermittently rubbing the main plastic body of the unit, making a horrible sound and melting some of the casing (only cosmetic). The motor mounting spacer had compressed on one side causing the belt to not run correctly. This was fixed with a small washer to correct the belt’s alignment.
With a little bit of grease, WD40, Brasso, contact cleaner, repair kit and washer, the whole job took a couple of hours (including fettling time) and cost me under £8. Definitely worth the effort considering the price of a replacement Chef.
