*Buys sandwich griller to make a sandvich,
realises they're made raw.*
I cry evrytiem...
So here is how a sandwich grill works.
2.Remove the 3 other screws.
3.There are 5 more screws, remove them to reveal the thermal switch and fuse.
4.Fuse - This is a high current fuse that breaks the circuit when too much electricity passes through the wires, melting the metal alloy inside and preventing travel of electricity. These are one time use fuses i.e. once the circuit gets short circuited, the fuse needs to be replaced.The difference between the thermal switch and the fuse is that the thermal switch breaks the circuit once the grill gets hot, and is used multiple times whereas the fuse breaks the circuit during a short circuit to save the appliance and can only be used once.
1.High current fuse - A short circuit would cause the fuse to break the circuit. Since it is only for one time use, it will need to be replaced.
2.Thermal switch - The thermal switch, although designed for multiple uses, can get burnt, after which the griller will keep on toasting the sandwich even after the max temperature being crossed, thus burning it.
3.Heating element - Although rare, the heating element can get burnt due to constant and extreme cooling and heating, after which it will need to be replaced.

Well, if I bought it, might as well break it.
So here is how a sandwich grill works.
Procedure
 |
| I just love how my family managed to make a sandwich grill work for 10 years... It only happens in India. |
1. Lift the two grills by removing the 5 screws present on each side.
2.Remove the 3 other screws.
3.There are 5 more screws, remove them to reveal the thermal switch and fuse.

| The Thermal Switch |
Different parts of the sandwich grill
1.Thermal switch - This Bi-metallic switch breaks the circuit and consequently turns off the sandwich grill once it reaches a certain temperature, usually around 185°C. I have already explained how Bi-metallic switches work here.
2.Main element - This part actually heats up the grill above it to toast the sandwich. It is a thick pipe made of stainless steel capable of surviving high temperatures of usually 8 mm diameter with a coiled kanthel wire inside it and filled with a fireproof powder that is an insulator.

| Man, someone really needs to clean that. |
3.Grill - This is the part placed above the heating element that gets heated to toast the sandwich. It has a non-stick coating.
Fun fact - A special type of grill, the George Foreman grill was actually specially designed where it was angled so that all the melted fat and other fluids drained through the grooves and out of the sandwich into a removable tray, and was marketed as a way to 'knock out the fat'. When I told this to my mom, instead of buying it she said to me other people are dumb and that we should just put our whole toaster at an angle to make the sandwiches healthier and save money. An hour later she was
wiping off molten chocolate off the kitchen counter and washing our grill sticky with all the mess. I'm telling you guys, some things only happen in India.
4.Fuse - This is a high current fuse that breaks the circuit when too much electricity passes through the wires, melting the metal alloy inside and preventing travel of electricity. These are one time use fuses i.e. once the circuit gets short circuited, the fuse needs to be replaced.The difference between the thermal switch and the fuse is that the thermal switch breaks the circuit once the grill gets hot, and is used multiple times whereas the fuse breaks the circuit during a short circuit to save the appliance and can only be used once.
Problems that could come up
2.Thermal switch - The thermal switch, although designed for multiple uses, can get burnt, after which the griller will keep on toasting the sandwich even after the max temperature being crossed, thus burning it.
3.Heating element - Although rare, the heating element can get burnt due to constant and extreme cooling and heating, after which it will need to be replaced.
Theory
I guess I don't have a theory part, as everything here is pretty simple to understand. Sorry guys!! I'll find a more complicated appliance next time!!
