What a scam. I am a professional electronic technician trained
in safe practices in electrical work and they won't sell me the replacement switch. I will source a suitable replacement from one of the big electronics supply catalogs. This will be my last Bunn coffeemaker.

Due to UL listings, warmer switches can't be sent out but your brewer can be sent in for repair. If you will call customer service at 800-352-2866 with the model and date, we will give you the cost and address.

you might have burnt the thermal fuse.
those need to be replaced, they cannot be reset.
be careful, it failed because the normal temperature switch failed and it overheated.

do not try to run it without a working thermal fuse. it could melt or start a fire

The Bunn coffee maker does not operate as most coffee makes do. You cannot leave the Bunn in the off position and then just flip the switch to on and pour the water in. You will always get cold coffee if you do this. It takes time for it to heat the water. The On/Off switch should be left in the On position all the time. This keeps the water hot in the tank, thus providing hot water when you need to make coffee. You then just pour the cold water in the top, shut the lid, and have a pot of coffee in 3 minutes. The On/Off switch is a vacation switch, and you use it only when you are not going to use the coffee maker for a couple of days. Older Bunn coffee makers did not even have an On/Off button. You simply unplugged them when going on vacation. So turn the switch to the On position and leave it there. The unit will then work as designed. Forget how other coffee makers work, this is a Bunn and it is the fastest coffee maker you can buy and must be left on all the time. that way the water stays hot and the unit will keep it that way.

I'm going to presume that your brewer is a VPS series pour-over brewer. This problem can be caused by several things, so I'll list the most common ones.
1) The on/off switch for the lower warmer could be burnt out.This switch also operates the heating element.
2) The high limit thermostat quite offen blows on the older VPS brewers. this is a small unit held down to the top of the tank and has 2 wires voming to it.
3) Look for burnt-off wires. These models sometimes burn off wires on the top of the heating element.
4) If none of these work, then your problem will be your heating element itself.
Parts for these models are readily available from your local Bunn repair shop.
