Title
Mr. Coffee IDS77 Grinder Thermal Fuse Replacement
Introduction
Once you remove the grinder cup you can see the following,[br]
Just remove the three plastic hole cover knobs, which you can simply pull out using tweezers or by lifting one side with a sharp point like that of a knife. Once removed these knobs look as shown below.
Get a small flat head screw driver and remove the three screws. Then you can simply take out the motor compartment. You'll need to pop the button panel to find a bolt holding the circuit board. You'll be able to figure out hopefully.
Once the motor is out you can see the thermal fuse wrapped inside the yellow tape covering the motor winding as shown. I cut the pins of the fuse and it's shown left to the motor.
Now it's time to find a replacement. The original fuse that's there in this one comes from China and here's a [link|http://www.homface.com/homby_2172037_H4F-TAM-thermal-cutoff.htm|link|new_window=true] I could find on it. A close up picture is given below.
I found several options in ebay, but either they had low ampere rating or too high functioning temperature. Also, it'd take more than a week to arrive. In the end, I decided to go with an alternative one from RadioShack, which in fact is cheaper (~$1.40) than options from ebay.
If you need some instructions on how to solder these look at [link|http://www.tamurathermaldevice.co.jp/e/product_thermal-cutoff/attention.html|this|new_window=true]. This one has a high ampere rating, but from what I [link|http://www.us-electronics.com/files/Thermalcutofffuses.pdf|read|new_window=true] having a higher ampere rating than the one used does no harm. It's the temperature that's important.
Once soldered, the unit is alive again.
Note some have just directly soldered the wires and someone also bridged using a piece of solder diameter about 1 mm and about 30 mm long.
