Me too!

As others have diagnosed. it’s likely an intermittent connection somewhere in the path.

Which means … the intermittent giveth and the intermittent taketh away. Don’t be surprised if it stops working again.

Was surprised to see that despite 6 hours of no power, all the frozen food items in the fridge were still frozen and all the other items – milk, veges, eggs, etc., – were still rather cool (temperature wise, that is).
Of course, we avoided opening the fridge door during the outage.

When we bought a new fridge about a year ago, the sales person told us that we could expect it to last about 10 years before it dies.
In my basement, still working just fine is about a 40 year old fridge; just keeps on ticking.

So I ordered a new switch from an on-line appliance parts company. All it required to remove was to turn off the power at the breaker and use a putty knife with a thin blade and it popped right out of the sheet metal. Remove the connector, put it onto the new switch, and pop it back into it’s little square hole in the sheet metal. Turn the power back on and (as Otis said), “Wallah!” Working light switch.

I tore apart the old one, and what had failed were the ultra-cheap electrical contacts of the mechanical switching mechanism. Instead of silver/cadmium-oxide contact surfaces they were some cheap contacts, visibly corroded and no longer making an electrical connection.

Two years later the new switch started going bad, so I ordered 2 switches this time. I’ve still got one as back-up.

I once did that with a knee-pedal-operated sink in a deli, I would tell new hires it was voice-activated, and then watch later to see how much time they spent yelling at the sink. Most people figured it out very quickly, thankfully.
