I purchased a Presto Scandinavian at a thrift a month ago. It worked fine the first three times, then the electronics flaked out, the clock failed and it stopped responding to any of the switches. Similar problems have been reported by others so I wasn't surprised at this outcome. I'd like to rewire the machine to circumvent the electronics and manually switch the heating elements.
The bottom of the casing is easily removed by screws to expose the circuit board that controls switches, clock and relays, but I can't figure out how to disassemble it any further. The main relay that switches the AC current to the heating elements is up in the throat of the housing where I can't reach. Do any of you have experience in rewiring this machine that you would be willing to share, or could even give me some tips on how to take the housing apart so I can follow the wires and work out the logic?
Thanks,
Tom
