This is all covered in my book "How to effect certain death with household items".
Maybe they didn't make it to run longer than 12 hours; does it get
worryingly hot to touch on the outside, and does it go a bit bendy and
soft after 11 and-a-bit hours? If so, try a slo-cooker instead.
In answer to your question, you will need a logic probe. (available
from R.S., probably). This will let you 'feel' for the track on the
circuit board which does the business.
1. Connect probe to the power rails of the circuit board behind the
clock/control screen (if it has one, else look around)
2. Switch on the oven.
3. If still alive, step gingerly into rubber soled shoes at this
point, ideally this would go before step 1.
3. Prepare to make observations after 11hrs 56 minutes (gives four
minutes for haphazardly wrapping 3 rubber gloves round the tools with
which you are using to hold the live electrics open)
4. Grasp the probe in your dominant hand, and using a random stabbing
motion, select a track on the circuit board and watch what happens to
the indicator on your logic probe when 12 hours ticks by. Choose a
track near the output-ish end of the board (relay town)
5. If nothing happened, you now need to select another track, at
random, and observe its behaviour. Return to step one and try again,
12 hours and all.
6. When your step 1-5 loop results in a beepy signal and flashy lights
on your probe, you know which track you have to patch. Simply solder a
patch lead between that track and the high or low rail (according to
your probe reading).
7. That's it! You're done. |
