Common symptoms for troubleshooting

• Firing duration is weirdly high
• Pieces are being fired inconsistently (some are over-fired, others under-fired, within the same firing)

If you think something is going wrong in the kiln, check the relays first!

Relays

1. Disconnect power from the kiln
2. Note the wiring (take photos)
3. Remove the relays individually, testing them on the bench power supply
   1. 3 terminals will receive power
   2. Connectivity when power is supplied should be present through the remaining sets of terminals
   3. Verify the relay pinouts to be sure on which terminals are used
4. Ensure all spade connections are tightly coupled. It should require fairly significant effort to disconnect the relays. Tighten with pliers as needed.

Kiln elements

1. Verify that the thermocouples look okay, not damaged, and no pieces or shelves are too close (this could cause a false positive).
2. Disconnect power from the kiln
3. Open the front control panel
4. Note the wiring (take photos)
5. Remove the screw terminal connectors which attach to the elements
6. Using a multimeter, record the resistance of all 6 elements
7. If any of the 6 elements are more than 10% out of spec, replace all elements (values are recorded below)
