|replacing the paragon sc2 muffle||or look at larger kilns at paragonkilns.co.uk|
In the factory, screws are put in tightly with an electric screwdriver. When removing them, use the correct-size screwdriver. As with any screw, the wrong size screwdriver can damage the head, making it difficult to remove.
The muffle has two elements, one on each side. Looking at the back, the power is connected to the bottom-left element tail, passes through the left-hand element and reappears at the top-left element tail. This is connected, by a separate external wire, to the top-right element tail. The power passes through the right-hand element and the power is connected to the bottom-right element tail.
If you have a multimeter, you can check the resistance of the elements. Make sure the kiln is unplugged. For an SC2 the resistance will be about 33 ohms. If there's no reading, the element will have failed.
The video shows a bead-style thermocouple held in place by a thin metal strip. Kilns made for Cherry Heaven have a longer-lasting sheathed thermocouple screwed on to a wider metal bracket. Remember to fix this to the muffle before fitting the muffle.
The muffle has to be aligned so that the door closes without binding. Put in one top screw, and check the alignment. Put in one bottom screw, and check the alignment. If everything is OK, put in the remaining screws.
|THE CHERRY HEAVEN MAINS TESTER SCREWDRIVER|
Mains voltage is AC, The mains tester screwdriver detects the mains, and allows you to follow it though the cables, the transformer, the relay, and the elements.
The Cherry Heaven Mains Tester Screwdriver.
The mains tester screwdriver contains a current-limiting resistor and a small neon bulb. When the screwdriver tip touches AC mains and you touch the screwdriver's end cap, a tiny current earths through your body and the bulb lights.
It's rated for 220V-250V, has a 60mm blade, and a pocket clip. It's also just right for wiring plugs, fitting sockets, connecting lights, and wiring dimmers. The blade is particularly hard and durable.
|THE CHERRY HEAVEN DIGITAL MULTIMETER|
The Cherry Heaven Digital Multimeter lets you test electrical equipment. Using the two leads, you can typically measure continuity, DC voltage, AC voltage, DC current, AC current, and resistance.
The Cherry Heaven Digital Multimeter.
Most multimeters are broadly the same: you set the range using a central dial. The most important thing is not to let the leads touch anything other than the contact points you're testing.
It's ideal when servicing or repairing your kiln. You can check the mains voltage, the plug fuse, the kiln fuse, the transfomer, the relay, and the elements. And you can test batteries, bulbs, cables, christmas lights, doorbells, fuses, power adapters, relays, switches, and wires, as well check most domestic electrical equipment.
Some multimeters can check diodes and transistors, measure temperature, measure frequency, and hold the displayed result after you've taken the leads off.
You can buy one in the on-line shop. However, the photo is of a typical multimeter and the ones in stock may not look quite the same.
If you're not familiar with a multimeter, you can practise by checking the DC voltage of a torch battery, the resistance of a normal 13A fuse, and the resistance of a torch or mains bulb.
