Hello,
I'm looking for advice on the best way to proceed on repairing a Cuisinart rice cooker. The fault is that the thermal fuse has blown.
The fuse is an SEFUSE SF169E, rated at 172 degC. I'm given to understand that these will eventually blow because the resin softens before the critical temperature, and the widget inside eventually goes open-circuit.
The original fuse was crimped onto the supply wires, and my thought is to replace the crimping with ceramic terminal blocks to make the next replacement easier.
The original fuse had an (electrically) insulated sleeve, and I had to cut this away to find out what was inside. Clearly, as the fuse carries live current and the case is earthed, I need to replace the sleeve with something temperature-appropriate (i.e. won't melt / burn / etc. at operating temperatures).
So, two questions:
- Is the idea of terminal blocks sound? There are no significant vibrations when the cooker is operating.
- What should I buy to replace the insulating sleeve?
Thanks for all advice...
