Mr. Coffee IDS77 Grinder Thermal Fuse Replacement

ID: 170882

Description: My Mr. Coffee Grinder IDS77 stopped working....

Steps:

1. Once you remove the grinder cup you can see the following,

2. 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.
3. Once removed these knobs look as shown.

4. Get a small flat head screw driver and remove the three screws. Then you can simply take out the motor compartment.
5. You'll need to pop the button panel to find a bolt holding the circuit board. You'll be able to figure out hopefully.
6. Once the motor is out you can see the thermal fuse wrapped inside the yellow tape covering the motor winding as shown.
7. Cut the pins of the fuse and it's shown left to the motor.

8. Now it's time to find a replacement. The original thermal fuse comes from China and here's a link for the TAMURA TAM Thermal Fuse Cutoff 127℃ 250V 3A H4X Square Temperature Switches. A close up picture is shown.
9. An alternative thermal fuse from RadioShack, which in fact is cheaper (~$1.40) than options from ebay.
10. The Radio Shack thermal fuse has a high ampere rating, but from what I read having a higher ampere rating will be suitable. The temperature is what is important.
