high, med, low switch on paragon a-99b

updated wed 24 dec 03

 

Arnold Howard on mon 22 dec 03


Taylor, 4-way rotary switches for your A-99B are available from Paragon, but
the original switches are no longer made. The replacement 4-way rotary
switches, made in Spain, are deeper than your switches. Depending on the
depth of the kiln's switch box, it is possible for the new switches to burn
out due to contact with an element connector. It is likely that you will
need to install 1/4" offsets on your switch box to move the switches further
away from the kiln.

A 1/4" offset is a 1/4" long steel collar that fits between the kiln case
and the switch box. The offsets are placed under the switch box screws. The
offsets are available from hardware stores.

We are adding the A-series wiring diagrams to the website, and have already
added the A-series instruction and service manual. Since we have not yet
added the A-99B wiring diagram, I will mail you one, Taylor, if you send me
your postal address.

Testing the A-99B (and all the other early Paragon A-series) is fairly
simple. An ohmmeter reading at the cord checks the entire electrical system,
including wire connections, switches, and elements. I will be glad to send
A-series ohmmeter instructions to anyone who wants it. We will also load the
instructions in the next few days to our website.

Ordinarily, when an A-series kiln does not fire, it is because the Kiln
Sitter contact block is corroded. That can usually be repaired by cleaning
the contacts with a pencil eraser. (Never use emery cloth.) The contact
block is not difficult to disassemble if you are careful to catch all the
washers and nuts as they fall out of the contact block.

Arnold,

Thanks for the reply. I did find a Paragon parts sheet and just ordered
the switch. I found it impossible to find parts lists on the Paragon
sight, however. A google search for 'kiln switch' turned up a supplier
link to a pdf. 2002 prices but correct part numbers.

Reconfiguring the switch box will be a snap, thanks. I did have the
sales dept. send me a wiring diagram for the A99B. If the ohmmeter
instructions will soon be online, I won't bother you with sending me
some via snail mail. That's a small 's', Snail. The kiln sitter is my
next project. Thanks for the heads up regarding the contacts. I will
be looking for that.

I am very excited about this kiln. It is 30 years old, but it is in
excellent shape. This kiln is going to be my second class in kiln
repair/maintanence. Fun.

A used kiln can be a great bargain. I've seen 30-year-old kilns at the
Paragon factory sent in for a change of elements. The bricks are immaculate
on some of them. The paint on the outer surface of the lid is still intact.
When a kiln is treated properly, it lasts many years.

I will have more instructional materials loaded to the website as soon as
possible.
