kitchen mixer/universal transformer repair

sound like its a 130 degree thermal fuse

Thermal fuse, I'd say. Most of the electronics places - RS, CPC, Rapid etc.

But Maplin may be your best bet as they don't have a minimum charge at a shop. A 128C one is RA15 and costs 49p. Note the installation instructions - they can't be soldered.

And you reckon she has?

thanks to you both. Didn't think of a fuse (wouldn't be simple to change though) any idea what the M3.3 would be. wife says only 2 or 3 minutes but hey ,who knows

What is the usual alternative to soldering this fuse

For a quick check, just bypass the thermal fuse and make sure the mixer does work before spending too much time looking for a replacement. If you want to take a small chance, just permanently bypass the fuse, make sure your wife understands that she can overheat the mixer if she uses it more than 5 minutes at a time.

The thermal fuse blowing is probably infant mortality, just like many things that either fail when very new or else last a long time. If you make a graph, and you plot failures on the vertical scale, and time on the horizontal scale, you are a victim of the early failures. The overall curve is frequently called a bathtub curve because the shape of the curve is like the profile of a bathtub, high at each end and low and wide in the middle. Probably more than you wanted to know :-)

if you are fast, you can use long nose pliers as a heat sink and quickly tack solder them in place....

if you are going to solder it.... buy a couple of these when you go to the parts store..

you'll probably need to practice...
