Is the thermocouple worn out?

A worn thermocouple can cause an

Electrical noise from a chattering or buzzing relay can cause an
Multiple zone kilns: is the lag temperature set too low?
I
"Lag" is the difference in temperature that the controller will allow between zones. You can adjust temperature lag.
The lower the temperature lag, the closer the temperature between zones. A low temperature lag can slow the fir-
ing, because the controller stops firing progress to wait for the zone temperatures to even out. This can cause an
code. Use a higher lag temperature, or use a delayed temperature lag. (See the multiple-zone instructions.)
Err 1
Kilns with a power connection fuse box: has a fuse blown?
I
A blown fuse in the power connection fuse box will shut down one of the relays and its elements. This could slow the
kiln down and cause an
Does your kiln have a door or lid switch?

The door/lid switch shuts off power to the relays when the door/lid is opened. Electrical noise from a door or lid
switch can cause an
