Look at the map this is just higher near larger population, Correlation vs. Causation. This smells like bull shit.

It’s a “safety capacitor” used across AC, similar to a Y cap, they have a known failure mode that is designed to not cause fire.

Honestly this is not worth the risk, It looks like a simple enough repair a high watt resister a cap and possibly an IC (U1 looks burnt) BUT consider this, something happened to cause the failure and that something could still be around, like a short in the heating element of the throw. Whoever designed this obviously did not test the failure mode of the device. The reason things are UL rated (other certs for non US) is that they get tested and found to not fail in a manor that will cause harm to the user or fire. The failure mode of this device could cause a fire, if you repair it and the same thing happens. . . . Don’t risk it, Toss it out.
ALSO NOTE! if you do attempt it. That cap is most likely a class X2 cap and would need to be replaced with the same, don’t use just any cap!
Happy Canada day to our northern neighbors, sorry for being the bad eggs over the fence :(

Get into Ham Radio, not just get a license and talk, get into it. make your own radio, antennas, learn the science, learn firmware programming and microcontrollers, everywhere you turn there is something new to learn and puzzle at. And you can help with community service things (only if you want to). It’s great because you can go as deep as you want (or as shallow), keep your mind engaged and have fun doing it.

From my perspective, Keep it. You should ask your SO though.
Seems odd to have that down during field day.

I have a project that is using a Teensy 4.1, the cheep 5v regulator I was using in the project let the magic smoke out for no good reason. I replaced that but now the Teensy boots and runs for about a min then quits. There is a TLV75733P power IC that is supplying the 3v3 and it gets hot then quits supplying power. Since that IC is $0.46 vs a new Teensy 4.1 ~ $40 I want to try and replace it. I have done a bit of SMD work but not tried to remove a tiny chip with a GND pad before so I’m looking for any tips. The PCB of the Teensy has header pins so I can’t really get good contact to a hot plate to preheat the board.

I also saw where they used a graphic of the entire US when the study only encompasses 1 county in California.
