Kenwood Chef A901 -a fishy story!

If your Kenwood Chef A901 starts to smell of burning, don’t despair, it can usually be saved.


I had an enquiry via this site from a fisherman who was very upset that his trusty Kenwood Chef A901 had given up the ghost.  Rather than using the Chef to make Victoria sponges, it had been used to prepare fishing bait.  It just demonstrates how versatile these machines are.

FixItWorkshop, Oct’17, Kenwood Chef A901 with motor speed control fault.

Whilst it was in use, the owner witnessed a bang then the smell of burning before the machine came to a halt.  The plug was quickly pulled!

Whilst discussing the fault on the phone, I suspected that the fault was probably due to the failure of the motor speed control circuitry, which is known to fail with age.  I had carried out similar repairs to other machines, including my own (in this blog) so agreed to take a look.

I received the machine quickly and upon inspection, the machine had obviously been cared for and considering its age, was in good condition.  The smell of burned-out components was clear, lifting it out of the box.

Dismantling the machine and removing the motor on the A901 is fairly straightforward, providing you allow time and make notes on where things go.  The components that need to be replaced are very accessible and anyone with moderate soldering skills would be OK with this task.

Luckily, the Chef is very well supported by long-term aftermarket suppliers and I bought an off-the-shelf spares kit at £14.10 delivered, from KAParts ( via eBay, featuring upgraded components.  This kit is a little dearer, but component technology has moved on since this machine was first on the market, so fitting anything else is a false economy in my opinion.

With the old components removed and replacements fitted, the motor ran smoothly and fully reassembled, the machine is now ready to mix bait mixtures once again.  Lovely.

Cost of a new machine: Circa £300 and up.  Cost of repair:  £44.10 (kit plus my time).

Here’s a little video I made of the repair.

Smelly Kenwood Chef A901

FixItWorkshop, Worthing, Jan’17.  Repaired 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.

Here’s a picture of the new components fitted in situ…
