20 Most Recent Bunn BTX-B ThermoFresh 10-Cup Home Thermal Carafe Coffee Brewer, Black Questions & Answers


This is a common question for the BTX-B.
It's a commercial brewer that needs to be pre-filled prior to turning on.. It also needs to be filled again with a full carafe for it to brew properly. I have a link below that will explain how to set up and use this brewer.

There is a recall on certain makes of pots for the gaskets. They have a pot repair program that costs money, or you can request the parts from the company they will send you the parts and instructions on how to replace defective part if your pot is part of the recall.

The Bun BTX-B has a pair of thermal fuses located on top of the water heater storage unit. If the pot is left without use for a week or so, the thermal fuses will blow if the top of the tank gets too hot (about 150 degrees Fahrenheit) due to the evaporation of water in the storage tank. The operating directions state clearly that if the unit is not going to be used for a few days to turn off the pot. These are there to prevent a fire in case someone does not follow the direction. This is the "MOST" common form of electrical failure in these pots.

To access the thermal fuse
1. Unplug the pot and drain pot by inverting the pot in an empty sink.
2. Remove the two Phillips screws located under the water fill flipper door.
3. Gently insert a small flat blade screw driver into the front top of the lid and remove top cover.
4. Remove the 4 screws inside the water routing tank and remove routing tank simply by lifting off.
5. The thermal fuse is mounted to the top of the tank under a clip and is easily slid out from under the clip. There is a brown wire (goes to power cord neutral) and a black wire (goes into tank disk access hole). Simply measure with a multimeter at lowest ohm setting, the meter should read continuity between the black and brown wires, if it reads an open circuit, the part is bad.

A replacement thermal fuze assembly kit is available off e-bay for about $10. You can buy individual thermal fuzes and replace one of the two that is bad for about $3, but I recommend the kit for most consumers as it comes with wire crimps already mounted and far easier for the average person to simply install. Repair takes about 5-10 minutes.

Try running some cleaner through the system. May have to do this a couple of times depending on the type of water you have.

Warranty is 1 year parts and labor, 2 years parts only and 3 years for control boards. That model does not have a control board. You could have a bad thermostat, bad high limit, bad thermal link or bad element. Without you having a multimeter anSd the knowledge of how to use it properly it would be best to replace the unit.

Is the power switch on the side turned on? Is the outlet it is plugged into functional? Try plugging something else in there.
