Hello Everyone,

I have the mentioned above electric hot plate and it has a large and small plate.
recently the large plate red light doesn't light when I turn it on, or heat up.
the small plate works fine. I took off the back of the hot plate to find out what is the problem because I had a hot plate before and I fix it one time. with this one I located the problem, but don't know how to fix it. In the picture there is a yellow arrow pointed to where the problem is located if I'm right about the diagnosis. in the small plate there is these two small copper dots, in between the metal touch each other and spark when you turn the plate on/off and then the red light turn on and the plate starts to heat up that is what happens when I turn it on, in the large plate the two dots touch each other but don't make an electric spark, the red light doesn't turn on and the plate doesn't heat up. this what I found when I checked all the connections and wires. please help me with a picture or video if u can. thanks a lot

 

by the way this picture for a different model but the internal parts are the same as in the model I have!

 

Welcome to the forums.

That device you're pointing to is the thermostat. It is a cycling thermostat. Those contacts arc every time the plate cools and the heater turns on. Those thermostats aren't considered serviceable but it could be difficult to find a replacement part for that unit.

Those two discs you mentioned are the contacts. If it is your intention to repair that thermostat then get some very fine black emery paper. Cut it in 1/4" strips and place it between the contacts and slide it thru the contacts facing one side then the other side. You just want to burnish the contacts clean. This method will only work for so long as one the contacts get pitted and burned they keep getting worse.

Good luck !

 

wooow that was a quick reply to my question
thanks so much. i'll give it a try, will look up where I can get the emery paper, hopefully it will work, if not i'll just work with the small plate till I buy a new one ...

 

Use a multitester and check continuity of heating element. It just might be burned out.

well, I tryied the emery paper it did not work, but I noticed that these two copper dots "thermostat"
look like they are burned, because it looks like shiny copper in the small plate while it looks dark and burned in the large plate. well I just put it aside and give up on temporarily.
any way thanks a lot for the replay...

 

If the contacts are that bad you could try something a little coarser on the burned side.

If you'd like to consider replacing the thermostat..... it should have a temperature rating on it.... usually in degrees Celsius. If you can find that operating temperature I'll tell you where to find it.

 

I don't know how to find out this. plus even if I find it, I don't know how to replace it this part of the thermostat is very tiny and complicated and I don't have any tools to help. well, if any one here have a repair store near los Angeles area I could bring in person if the repair services is affordable. thanks

 

good news about my hot plate, I went the store where I originally bought it and ask if they fix these kind of errors? and surprise, they took it and gave me a brand new one for an exchange of $5 . that was a good deal, right! well, they shouldn't have ask for money since it's under warranty, but I didn't have the receipt or the packaging and it wasn't in a good condition anyway.

 

Without having the receipt...... $5 was a bargain. Happy cooking
