Question about Mr. Coffee 072179228578 12 Cup Coffee Maker
I read about the thermal regulator, but how do you get to it to reset it?
I need coffee!! Please help!
SOURCE: my bunn is too slow
Use the de-liming spring to clean the copper tube behind the spray head. Pour several pots of clear white vinegar through the unit to further remove lime and scale from the interior of your coffee maker. My Bunn is 24 years old, and the only replacement parts I've ever required are new carafes and the 4041 silicone washer repair kit.

There is a thermal fuse of poor quality in every one of these machines to protect against fire.
If you are unlucky, it fails early and at a safe temperature, if you aren't it may hold forever.
Two years ago, I had three coffeemakers fail in two days; I got a refund instead of a fourth.
Because the parts are spot-welded together, these machines are essentially unrepairable.
If you want to peer inside, look for a cylindrical part about 5/8 " long with one pointed end; this is the thermal fuse.
DON'T consider bypassing it, I know of one counter that caught fire after the thermal switch that controls the heater got stuck.

Try running a cupfull of vinegar through it followed by a pot of plain water.This will remove any hard water deposits which may be blocking the tubes.

All coffee makers use a thermal fuse which opens
(interrupts) at a specific temperature, generally somewhere above boiling point
and do not reset when cool.
They are designed to prevent fires if the
thermal switch which cycles the heater fails and the heating element heats
beyond its normal operating temperature.
These Chinese devices are poorly made and
unpredictable in performance.
They are not user-replaceable since they are spot-welded on both ends; the only possibility is the replacement of the pre-assembled heating element/thermal switch/thermal fuse which will likely cost close or equal to the price of a new machine if at all available.
