Kilns are very important tools of trade for people in the pottery industry. It can be disheartening to wake up one morning only to find that your kiln cannot work. However, you do not have to be stranded since repairing a kiln is not difficult and you can do it all by yourself.
The first step of repairing a kiln is identifying the problem. The common parts of a kiln that cause kiln breakdowns are the elements, connectors, and lids.
Element of the kiln
An element is one of the most important parts of a kiln and in many cases; it is the cause of kiln problems. An element will go on for as long as possible but the more it fires the more its efficiency decreases.
You can establish if the element is the reason why your kiln is not working by running a screw driver on the elements to check for burn out holes. If you find a burned out area, apply kiln-wash on it and then put in the new element.
In other cases, the element might burn at the connector and in this case all you have to do is replace the connector and save the element. When the connector burns off it breaks away and so you will find that it is missing.
To repair your kiln’s element, detach the control panel from the kiln and you will see the two connectors. Now take a close look to see if the element has enough length to fix another connector.
If the length is not enough then pull at the element’s end to the desired length and fix the connector. Once you are through, place back the control panel on the kiln and you are good to go.
Remember, the reason why connectors burn out is because of loose connection, therefore ensure that you tighten the connectors.
Other important parts of the kiln
Other parts of the kiln that are susceptible to damage are the lid and the bottom. Due to the constant pressure applied on the lid when opening and closing the kiln, it develops cracks after a period of time. Here is the thing, if you see that there are sags on your lid or huge insulating materials are falling off, then you have no option but to replace the lid.
If the hose clamps that are used to secure the steel flange become rusty then you have to replace them immediately. The bottom of your kiln might become overheated and will not be able to effectively complete the heating process.
In this case all you have to do is place the kiln on ceramic bricks so that it has space to lose the excess heat.
You do not have to worry if your kiln has broken down neither do you have to go out of business. Repairing a kiln starts with identifying the problem.
Check the element, the lid and the bottom. Once you are aware of what is ailing the kiln then you can fix it.
You can fix the element by tracing for burned out areas and fixing a new one. You can also replace the connectors if they are burned out.
Your oven cannot operate if your lid is broken so replace the lid and the hose clamps if they are rusty.
