Kiln Problem

Recommended Posts

I just replaced all the elements in my 1027 Skutt kiln. Loaded it and fired it. It glowed red hot, and all the elements were red, but it would not go over 1843. It held there for at least two hours, so I thought something was wrong and shut it off. My students will be frantic! What could be the problem with the kiln. We are firing to Cone 6 on the ramp/hold mode, and have been very successful up until now. Can anyone offer help?

You need to give a few more parameters here to know what your firing procedure is. First off, are you using a kiln setter? What is your firing schedule? Did you have your peepholes in? Why not let the kiln setter run with the standard amount of time and check it? Did all of the elements fire? You may have had one of them not connected. Check individual elements by turning on to high-place a small piece of paper to each one to check for heat(one at a time). Let us know this info, it may help with a solution.

Since this problem occurred after you replaced the elements, it should be related TO the elements.

Since you are using ramp/hold, you are not using a sitter, and you verified that they are all glowing red.

I am assuming that you did everything else that you always do when you fire, since we are all creaures of habit; this might be a dangerous assumtion, but I'll bet that you have the peeps in, lid closed, or whatever you have done in the past when you achieved success.

Did you get the correct elements for the voltage you are firing with? Elements for that kiln have different resistances, depending on the voltage you will use them with.

Do you use a program stored in memory to fire to cone 6, or do you program each time? 1843 F is suspiciously in the neighborhood of cone 06, so it may have be inadvertently programmed to 06.

I used the computerized programmer and programed it for ramp/hold to cone 6. I used my custom program as I usally did. I peeked through each peep hole to see if all the elements were red, and they were.

I used the ramp/hold which I custom programmed to cone 6. Lid closed, peeps closed, etc. The elements were the ones for that specific kiln. I think the top setting was for 2150 degrees. Could there be something wrong with the mechanism such as the relays?

After hearing this, double check your order numbers. Is it possible you ordered 240V elements when you needed 208V elements? This happened to me when changing a kiln from one school to another. The other kiln was 240V as the school was. My school was 208V. Juice wouldn't make temp.

The top and bottom elements should glow brighter than the center elements. If the center elements glow brighter, the elements are in the wrong position in the kiln. That will cause the kiln to fire unevenly and might also prevent the kiln from reaching cone 6.

 

If you suspect that you installed elements of the wrong voltage, check the kiln's amperage and compare the reading with the amperage listed on the kiln's electrical data plate. Here is a video that shows how to take an amp reading:

 

 

 

Please let us know how you resolve this problem. Good luck!

Wow it is great to have tech people watching post like this. The extra expertise with specific equipment will always be helpful.:)

When you say it fires to red- does it not fire to yellow? Sometimes new connections that heat up can be loose at high temp when they seem just fine at low temps... If it were my kiln, I'd go back and clean the connections to the new elements and then try again... if you still get no joy, take a look at your thermocouple... good luck! Tracking down electrical problems is a often thankless task...
