Coffee Maker Thermal Switches - Where to Get?

Geek · 10th January 2010, 07:05 AM

Hi Folks,

My wife and I have this fancy little coffee maker that eats thermal switches. It's our 2nd one in three years and I've replaced the switch on both until my scavenged supply runs out. @ $150 a pop, I don't feel like averaging ONE a year with switches lasting only 4 months on average (ever try to deal with an Oster warranty depot? Don't buy one!

)

Any ideas where I can get these little bi-metal switches in less than 5,000 lot?

Cheers!

Is this what you are looking for?

Digi-Key

How about these

Digi-Key - 317-1443-ND (Manufacturer - R2009015A119)

just go to digikey.ca and search Temperature Regulators they have all different temperature ones.

by the way did you ever use those knobs?

OMG

I spent two hours on Digikey, enetring search terms and even downright browsing and I never found them.

(Steve, your link is shot)

Thanks guys!

** edit **

They don't have the one I need though... one like Neutron7 shows in his link, but 145C.

Once you get the replacement switch, add a triac and resistor so the switch does not have to switch the full current.

Thanks... but whatever idgit wrote their website, it doesn't work in Firefox

Cheers!

now that you mention it, I remember that I had to fire up IE. On the other hand, they had the parts for the refrigerator, microwave, dryer, and maybe one or two other appliances that I have repaired over the years.

Cities of a reasonable size usually have some shop that sells replacement bits for domestic appliances. Check the yellow pages.

Sometimes those switches aren't meant for temperature regulation, just protection. Is there a real temperature controller that has failed?

Thanks again guys.

Actually, there is a couple of ancient shops in the yellow pages that just might have them.

Typical coffee maker fashion, it's a single (as opposed to the older dual - one on the hotplate, one on the element) switch on the element rated 293F (145C) and has a thermistor on the opposite side. The bimetal click-switch works to make the coffee (it's shot, so nothing gets cooked) and the thermistor is used to regulate the hotplate once it's done making the coffee.

If I unplug the click-switch, the hotplate will be on "keepwarm" between 65C and 85C, no problem, but the water doesn't boil to make coffee.

I had *one* switch of the right temprature, but it wouldn't fit, nor could I safely fudge it in. The switches that do fit, are all "keepwarm" click-switches, rated no more than 80C :-\

Cheers!
