On a DIY electrical roll this weekend - stove, toaster, computer, phone, and stove again [View all]

I didn't plan it this way, but the parts for stove and phone arrived yesterday (early I might add), so I fixed the phone and activated it, then fixed the stove. Saturday was to be toaster timer and computer OS install/troubleshoot.

Surprise to me I wake up and one of the OTHER burners on the electric smoothtop has gone out. I think it's the control, but have to multimeter it. Do stoves do this around 22 years old? Light bulb, control switch, burner over the last 2 years, and now more.

Multimeter skills, btw, very very good to know. Car, house, stove, water heater. I'd be dead without them.

And there's the toaster oven. Sears, with mechanical timer with a *DING* bell. The timer stops turning when hot at predictable places. I shot some silicone lube in there, and it loosened up, then 2 cycles later stuck again. Is it worth disassambly? ANyone know if there's a place to lubricate, or does dust clog it. Not sure whether to spend 2 hours and 30 screws of time, or just tolerate it until it burns out.
