When & how do I conduct a Full Power Test to check elements

Slower or cooler firings, difficulty reaching temperature, uneven or abnormal results, and error codes are all common signs of worn elements. Relays, wiring, thermocouples, voltage supply issues, or controller problems can also produce similar symptoms. To specifically test element condition a simple visual inspection can be carried out using a Full Power Test - no special tools or tradespeople required.

All Olympic Electric Kilns supplied for the New Zealand market are fitted with an automatic shut-off safety switch. When this switch is disengaged, power to the elements is immediately cut. So, if the door or lid is opened while the kiln is heating, the elements will begin cooling straight away - making it impossible to properly assess their condition - unless the switch is engaged.

When carrying out a Full Power Test, ensure the kiln door or lid is fully open and the auto shut-off safety switch is engaged before pressing Start on the controller. Remember: when the switch is engaged, the elements are live. To avoid risk of electric shock NEVER put your hands inside the kiln while the shut off switch is engaged.

Use the fast heating programme below and, depending on the kiln model and size, wait 10-20 minutes then visually inspect each element. Looking from outside of the kiln only, check for any dull or dark sections that are not heating evenly. Feel free to get in touch with your kiln and controller model and we can email instructions or talk you through the process.

Fast heating programme:

If you have the Genesis Touchscreen Controller, press LOAD, scroll up and select CUSTOM, then User 12 - "Full Power Test".

For the V6-CF or Kiln Star Digital controllers use the VARY FIRE option to programme a single segment schedule with a ramp rate of 9999, up to 400ºC with no hold. 

You may have heard of using paper or other flammable material to test the elements, however this is usually unnecessary. If you do choose to carry out a paper or any other test, to avoid electric shock NEVER touch the elements while the kiln is powered up.

A Full Power Test is carried out at the user's own risk. No responsibility is accepted for any errors, omissions, injury, loss or damage arising from the use of these instructions.
