Coffee Maker Thermal Switches - Where to Get?

[Geek]

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?

 

[Geek]

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?

 

[Geek]

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!

STO-250 Stancor Industrial Temperature & Humidity Sensors

Found this at mouser...

They have other temperature but none arround 293F...

Here is a chart from the datasheet :
STANCOR
Part Operating Range1
Sec. Number °F °C Function2 Differential3
STC-225 217 to 232 103 to 111 Closes 30°F 17°C
STO-230 224 to 236 107 to 113 Opens 30°F 17°C
STC-240 229 to 251 109 to 122 Closes 100°F 56°C
STO-250 244 to 256 118 to 124 Opens 30°F 17°C
STO-325 315 to 335 157 to 169 Opens 50°F 28°C

You'd have to see if you need it to Open or Closes at the required temp :S

Hope it help!

you can give them a call or email. I think they will give you reply in a short time.

OK, thanks 🙂

Hi Geek, I am an avid FF fan and when I run into these sites, I get around the annoyance by loading the site into an IE tab in FF. To do this, simply load the "IE Tab" addin into FF. Then when you run across a link to an IE only site, just right click and choose "open link in IE tab". These seems to work for me on all of these sites...

Good luck..

I had to replace the thermostat a while back and used this, they may have similar products to what you need:

Gents, I found the solution in a less than likely place - get cheapie Oster secondhand at Value Village, dissect and fix!

Thanks for all your input. This info will prove invaluable for when I need supply for other items I found with these darn things (like a microwave that had FIVE of them to sense overtemprature)

Cheers!
