For ideal firing results, thermocouples in each zone should be close regarding how far they protrude into the kiln.
- Set the thermocouples 3/8 to 1/2" in from the ends of the tubes. Get them as close as you can. They don't have to be exactly perfect.
- Unplug or disconnect at the circuit breaker or disconnect switch.
- Open the control box to access the thermocouple blocks, then just loosen the two screws that hold the TC to the block, move the TC in or out as needed, then tighten up the screws.
- You might have to tap either end with the screwdriver to get them to move. Usually, they'll have enough adjustability that you won't need to mess with the washers.
