Need help with Mr. Coffee machine

I have a Mr. Coffee brewing machine. It is a PRX33 4198 model. The machine has the following selections for brewing coffee: 1) auto start, 2) on 3) 1-4 4) Clean. These selections are made by pushing the select button until the one desired has its light turned on next to it.

Its current problem is that it no longer seems to work. The digital clock shows the time, which indicates that it is getting electricity. The selection button works for only two of the selections: 1) 1-4 cups and 2) Clean. When either of these selections are made, nothing happens. In other words, no water from the reservior flows to the container.

Is there any way I can get the machine to work only on an "on-off" basis?? I would like to bypass all of the complicated stuff and just brew coffee in the simple way. We actually have an old fashion electric percolater coffee maker. I just want this as backup.

Thanks.

Don't bypass anything, the "complicated stuff" might be essential for safe operation of the machine. I'm not familiar with this machine, but the problem could be something simple, is there any sort of interlock switch, like to ensure a carafe is in place?

Probably a bad heating element... (?)

I had a water purifier that had a thermal fuse open up. Although these fuses (also called a thermal cut-off) are meant to prevent a fire, they sometimes open due to age. As long as you can determine their rated temperature, it should be safe to replace them. Using a magnifying glass, look for a rating printed on the body. It might be in either Centigrade or Farenheit.

I found a replacement at Radio Shack, where they had two or three different temperatures. They are also available from NTE.

Since heat will cause them to open, you can't solder them easily. The environment where they exist is also bad for solder connections. Therefore crimping may be the best option unless you have spot-welding equipment. Some come with small brass cylinders or ferrules that can be slipped over the wires for crimping. Otherwise you might use the barrels from a regular crimp terminal with the terminal part clipped off.
