How to Adjust the Paragon  
Lid/Door Safety Switch  
5 By tilting the switch, you should hear the relays turn on and  
· Wear firing safety glasses when looking into the peephole of  
off. If you do not hear the clicking, then disconnect the power  
to the kiln and look for a disconnected wire. If the wiring is  
okay, replace the switch. (You can also test the switch with an  
ohmmeter. See instructions on the next page.)  
a hot kiln.  
· Do not open lid or door until kiln or furnace has cooled and  
all switches are off.  
· DANGEROUS VOLTAGE! Do not touch heating ele-  
ments with anything. Disconnect kiln or furnace before ser-  
vicing.  
The safety switch on your kiln turns off the heating ele-  
ments when the lid or door of the kiln is opened. (The digital  
controller will continue to operate.) When the lid or door is  
closed again, the elements will turn back on.  
6 Adjusting the tilt switch  
changes the distance the lid  
opens when the elements turn  
off. You removed the tilt  
switch in step 4. With the  
switch out of the way, you now  
have access to the bolts that  
hold the switch mounting  
plate. Loosen the 2 bolts.  
Indications that the safety switch is out of adjustment:  
The run light on the controller is lit but the elements do not  
heat.

The safety switch turns off the elements part-way through  
a firing due to expansion of the door or lid at high tempera-  
tures.  
Loosen switch mounting plate.  
7 The 2 mounting holes are  
enlarged so that you can adjust  
the angle of the switch  
mounting plate. Raise  
the back of the mount-  
ing plate to increase  
the distance the lid  
travels before the ele-  
ments shut off. Raise  
the front of the  
mounting plate to de-  
crease the distance.  
We have included instructions for adjusting three types of  
lid/door safety switches:  
The Tilt Lid  
Safety Switch  
Top-loading kilns use the tilt  
switch to turn off power to the el-  
ements when the lid is raised.  
The switch is mounted at the  
back of the lid.  
Make only very small  
adjustments.  
Adjust switch mounting plate.  
8 Tighten the bolts in the switch mounting plate.  
9 Reinstall the tilt switch. Repeat step 1 to test the lid.  
10 Reinstall the tilt switch cover.  
1 Program the kiln to fire at full  
rate so the elements will turn on  
and stay on without cycling.  
(Please consult your manual to  
program a full rate.) After the  
kiln has fired for about a minute,  
have someone raise and lower  
the lid. Do you hear a clicking  
noise when you raise the lid?  
(The relays click when they turn  
the elements on or off.)  
The Door Rotary  
Safety Switch  
The door rotary  
safety switch is  
mounted on top of the  
door hinge shaft.  
2 If you do not hear the relays  
click, close the lid and lift the tilt  
switch housing by hand. You can  
usually adjust the tilt switch by  
bending the housing up or down  
slightly.  
1 Use a ¼” nut driver  
to remove the screws  
from the door switch  
cover. Liftoff thecover.  
2 Program the kiln to  
fire at full rate so the elements will turn on and stay on without  
cycling. (Please consult your manual to program a full rate.)  
After the kiln has fired for about a minute, open and close the  
door until you hear a clicking noise. (The relays click when  
they turn the elements on or off.) The elements should turn off  
when the door is opened 1” - 2”.  
3 If you still do not hear the re-  
lays click, remove the screws  
from the switch cover with a ¼”  
nut driver. Lift off the cover.  
Remove the tilt switch screws.  
4 Remove the 2 screws that se-  
cure the tilt switch. Remove the switch. (Note how it is aligned  
so you can reinstall it correctly later.)
