I’ve repaired a few Kenwood Chefs recently, but this one seemed worthy of a mention on these pages as it’s slightly different to the ones I’ve repaired so far.
Many Kenwood Chef accessories are usable on Chefs from all eras, due to logical thinking by the designers over the years and this is something to be applauded as it reduces waste. For example, the beater on a 1970s machine will fit one from today. An interesting fact for any occasion.
I’ve repaired many A701s and A901s, but this was the first A902/4, so I thought I’d share some of my repair experience in order to help others.
The owner contacted me explaining that she’d been using the family’s cherished Chef to make a cake when a plume of smoke started coming from the mixer. The smell was bad and she’d quickly disconnected the unit from the mains. The owner then contacted me to ask ‘was the Chef worth repairing’? Of course it was!
I suspected the infamous speed control components which tends to fail with age. However, this model featured extra components all mounted on a neat printed circuit board (PCB) which is fixed near the motor. A reasonably priced repair kit, with new rubber feet was available online so I ordered one up straightaway.
Opening up the A902/4 is a similar job on many Chefs and after removing a few screws, the motor and gubbins is available for maintenance.
As suspected, two out of the three capacitors on the PCB had blown visibly, due to crystallisation and general fatigue, so these needed to be replaced.
As all the components are PCB mounted, each part must be de-soldered first, contacts cleaned before re-assembly which is time consuming, but satisfying and even though I’ve done this kind of work many times before, I always take a couple of photos and mark wires with a pen or label, as it’s very easy to make mistakes later.
The kit included replacements for the faulty bits, plus some additional parts which should be changed as a matter of course. I also chose a kit with replacement rubber feet for the machine as the ones fitted had squashed ‘flat’ with age, a very common problem with the Chefs of this vintage.
New components fitted, the motor ran sweetly once again, without smoke, wobble or extra noise. It’s worth noting that the A902/4 is quieter than earlier Chef models and is probably worth seeking out if you’re in the market for a second-hand unit.
Another ‘happy little Chef’ leaves the workshop.
Cost of new machine: £400 plus. Cost of new parts: £15.24 plus my time.
