Is the problem random or intermittent?
If you live with technology (as we all do in the ‘20s), you will have encountered “internittent”. If you haven’t, wait. The nature of that beast.
You dress for rain, and it doesn’t. Or does. You teach your dog a new trick, and he does perform. Sometimes. You have a microwave oven that thinks it knows better than you. All equivalent, at the time. We have gone through a few moments with the magic box that boils our soup, and there was a solution.
You see, programmable gadgets rely on sensors. The number and size will vary, but they are in there, waiting for you to have a moment of impatience. And then – gotcha. In the case of the microwave, there were tiny (almost invisible to the aged eye) sensors that determined if the main door was properly latched. Safety, I guess. And over time, given that our oven was above the (other) oven, things got a little gummy. Remember, these sensors are not large, just efficient.
Someone on YT had the same problem, and enough patience to find a solution. For the rest of us, as his version was already solved. We were ready to remove the beast (oversize, with a ventilation fan, perched right above the cooking surface of the stove, which is made from fragile glass or ceramic or some such wizardry). Now, we won’t. We can happily boil our soup, and muffin and abything else. A happy day. Yesterday, the coffee machine. Today, the oven. Tomorrow: the world.
NO. I do not want to go old-school, with a wood fired stove. Been there, and got tired of random burn marks. If the electronic gear doesn’t always behave, at least my need for salve is lessened.
