My coffer maker - 2006/10/05 10:47
Hi,
My coffe maker uses same thermal fuse () and I'm not sure if it is broken or not.
1) I have a digital meter.How can I test if this thermal fuse is broken or not?
2) if it is broken, where can I obtain a replacement one?
please advise,
Regards, Faramarz

Faramarz,
Unplug your machine from the wall. Give it lots of time to cool down to prevent burns.
Set your multimeter to its ohm-meter setting (Ω .
Locate the thermal fuse, and if necessary move/remove any clips or plastic sleeve that are in your way.
Placing the two probes on the metal leads to either side of the fuse, check to see if it is passing current. If you see "OL" (overload) or the equivalent, indicating that nothing is passing through the fuse, then it is likely tripped (melted/open) and no good. Measure it more than once to be sure that you did so correctly.
If possible, it would be nice to know why it tripped in case it is malfunctioning. The fuse is there as a safety mechanism and to prevent fires.
I have no idea where you are located (somewhere in Ontario?), but check electronics supply and independent electronics stores. Radio Shack aka the Source does not carry them in my city. Neither did appliance repair shops. Is there an Active or Future Electronics store near you? Be sure to keep notes on how the fuse was assembled and either take the old fuse with you or write down all of the information from it; you want an identical part with the same thermal and amperage ratings. Probably only $2-3 dollars, so buy a spare.
The fuse is probably crimped on without any soldering. You don't want to solder the replacement without taking precautions to avoid overheating the fuse (e.g. placing needlenose pliers as heat sinks between the fuse and your solder point) -- use the crimps that come with it.
