PID troubles

Went to the garage to PC some bullets. Oven wont turn on, no power to the PID. Outlet tests OK.

I am no electrical guru but I open the box anyway. Even I could see the problem.

Wire to the switch was totally burned thru. A trip to the hardware store is in order.

Replaced the wire but it still won’t turn on. It may well be fried.

Worse yet is that the oven won’t turn on either. Wonder if the oven had a problem and burn out the PID.

Figured it out. Power cord was bad.
Noticed a GFCI in the bathroom was popped. Soon as I plugged the power cord in, not plugged into PID, the GFCI popped again.
Different power cord and all is happy. Wonder if I dropped something on that cord that lead to a short.

:) You just saved everyone from a loooong post I was almost done with.

I really dislike electric devices, I don’t understand them really well.

At least it wasn’t a tech issue, those just piss me off.

Fortunately, your issue was almost "mechanical" in nature, and resolvable without wizardry.

The ones that irritate me are those where a board goes stupid on you. You can't connect to the boards in household appliances and monitor, let alone change the program, and they are very "stupid" to begin with. I have a clothes dryer that, because of a firmware issue, will launch into full panic half-way through the week while sitting idle. Beeping, blinking, flashing,.... A watchdog timer times out, looking for/expecting some kind of signal to tell it that everything is hunky-dory, but that never happens. I've had to run it in test-mode for several weeks in a row until the fault will clear, because the way to clear the fault doesn't actually work. Once it clears, I unplug it after I do laundry on Sunday and it sleeps peacefully the rest of the week. I have a feeling this one won't last the forty-plus years the old Norge did that I started out with at t his house.

Glad you sorted it out though. The way things are made today can make an otherwise intelligent and resourceful being feel helpless. I built my PID unit from stuff I dug out of the trash at work, so no mysteries to wonder about. It was new stuff, but obsolete and no longer under warranty, so I made them throw it out instead of selling it to a customer. Later, it hit me - why do I care about a warranty if it's FREE? So, I went dumpster-diving.

Hot spot like that is because of high electrical resistance under even a normal current load for the system. Probably a bad crimp there, secondary problem to your cord. I like to solder stuff, even AC wiring.

My father was an electrical engineer and I think I learned how to solder before I learned how to ride a bicycle. When I started working on vehicles, I would always solder repairs, modifications and installations that involved electrical stuff. My friends and co-workers would typically use crimp connectors or just twist wires together and wrap some tape around the splice. My work was MUCH more reliable and rarely suffered failures. Eventually, some of my friends came to understand that a little extra work paid off in far better reliability.

Usually this happens because the clip itself does not make good contact with the male spade end. Resistance shoots up and burns the weakest link. It also is from the cheap chinese clips that go completly soft from and heat. Then the female side loses tension and that maybe what caused it to burn out from the poor contact.

It does not happen as much if you buy actual 3M connectors. Soldering can help A LOT.
