When the Kiln Sitter Plunger Overheats

When the Kiln Sitter Plunger Overheats

If the Dawson Kiln Sitter overheats, the white plastic plunger can get so hot that it melts. The easiest way to prevent this problem is to make sure the high temperature washer on the porcelain tube is pressed against the firebrick kiln wall. A spring wire retainer keeps the washer in place. This helps prevent heat from escaping from the kiln.

It is also possible that the wires connected to the Kiln Sitter contact block are loose or corroded, causing the block to overheat. This, in turn, overheats the plunger. Another reason for overheating is that the wires connected to the Kiln Sitter contact block are too light a gauge.

Wishing you a happy summer,

Arnold Howard Paragon Industries, L.P.
