Bought second hand one year ago but according to serial code plaque
fabricated 11 years ago. My bread making Unold 8695 delivered good bread
for more than one year now.
Beginning with last week begun not switching on immediately. One minute
delay became one hour today. Text on the small display is clearly dimmed.
Last week reset itself twice along the program. Eventually being able to
complete.
Producer amazingly has a spare âÂÂpower control boardâÂÂ. But sales
ended in 2020 and part may be even older. I am not sure it would solve.
I was thinking it may be an old capacitor. But I am not very good at
electronics. Suggestions? Thanks for sharing.
meter?
What is the useful shelf life of electrolytic capacitors?
Sorry this isn't more helpful but - it varies from manufacturer to
manufacturer, from type to type and from application to application.
Sometimes their working life is specified at certain temperatures, but
the relevant literature is not always available and shelf life is hardly
ever mentioned..
A capacitor that might last indefinitely as a decoupler in a pre-amp
could fail rapidly if it were in a power supply with high pulse
currents. Even if it started to fail, as a pre-amp decoupler it could
degrade quite badly before any drop in performance would be noticed,
whereas, in other parts of the circuit, any leakage would result in
"noisy pots" or some other very obvious symptoms.
Furthermore, a manufacturer with a good reputation might have an
occasional dud batch or may be take over by bean-counters and start
producing 'value-engineered' rubbish without any visual change in the
product. It would only be much later, when things began to go wrong,
that their reputation would be lost (and by then the bean-counters would
all be retired with fat pensions).
Well written and thanks.
Any hint from my previous posts about why I am experiencing described
faults? Delay at powering on expanded from a minute to an hour after only
two use cycles.
I am not familiar with the product but that time-scale suggests
something like a memory battery or super-capacitor needing to charge up.
Does it have a memory battery?
If it hasn't got a battery, then a failed electrolytic capacitor would
definitely be my next suggestion.
