Hi Arnold,

I was thinking I could use the spy holes, but after checking, I cannot =
see all the elements thru them.

Best regards,

Hi Alisa,

You might like the way of testing kiln elements that I was taught.

You take a book of paper matches, and put the paper ends in the kiln element
coils. The matches are thin enough that you should not bend or distort the
elements.

You put matches in every section of element, and then turn on the
electricity. You don't have to look so the door of your kiln can remain
closed, because relatively quickly (within 5 minutes?) the elements that are
heating up will cause the matches to burst into flame. The elements that are
not heating will not, in that short a time frame.

Regards,
Bonnie

Alisa, you can also check elements with an ohmmeter. If your kiln
uses 4-way rotary switches, an ohmmeter will check not only your
elements but all the wiring and the switches at the same time. If
your kiln is electronic or uses infinite control switches, you will
need to remove the switch box and check the elements at the element
connectors.

You do not need to disturb the wires attached to the element
connectors (with an exception--see below). Merely place the leads
of the ohmmeter on each pair of element connectors. If an element
is burned out, it will show as infinity ohms on a digital meter or
no needle movement on an analog meter.

If elements are wired in series-parallel, you could get a good
reading even when checking a broken element. Elements wired in
series-parallel will have more than one wire attached to an element
connector.

Another method to test elements: take an ammeter reading while the
kiln is firing with all switches turned to high position. Compare
the ammeter reading with the amperage your kiln is rated for. (The
electrical data plate on the switch box lists amperage.) If your
amperage is very low, you probably have a burned out element,
disconnected element wire, or defective relay.

With best wishes,

Arnold Howard
