Not a solution, just a safety measure. Please keep this unit unplugged until you find a solution for safety's sake. You didn't mention the brand, but some ovens have been starting on their own while the owner is away and causing an explosion and a house fire.
This
is almost always due to a defective or loose magnetron causing
electrical
interference and disruption in the control circuit board.Details covering some previous
models are in
their bulletin here. Even if your model is not on
the list, the same problem can occur.If
your magnetron was recently replaced, it may have loose mounting nuts
or bolts or maybe the wire mesh RF gasket was not installed or got
pinched.

I don't know where you got the information that the high voltage capacitor takes 24 hours to discharge. The capacitor will actually discharge after a few minutes. If in doubt as to whether or not a capacitor is still charged, however, you should short the capacitor to discharge it. You do this by fashioning yourself a grounding probe:
1. Take a screwdriver and a set of alligator clips with a wire.
2. Connect an alligator clip to either end of the wire.
3. Connect one clip to the screwdriver and the other end to equipment ground.
4. Short the screwdriver across the capacitor terminals.
If the capactor casing is grounded (mounted to the equipment chassis) you only need to take a screwdriver and touch each across each terminal to the capacitor case.
CAUTION: Make sure the unit is UNPLUGGED prior to servicing any components inside the HV network. The HV network consists of the HV Capacitor, Magnetron, HV Diode and HV Transformer.
If you still have questions, please post back and let me know. I hope you find this information helpful.
