Kiln · Jen-Ken
Jen-Ken replacement elements
Jen-Ken is best known for glass fusing kilns, and the Chili Pepper and Bonnie Glo lines are built specifically for that work, while the AF3P series covers a broader multi-purpose range.

Jen-Ken element specifications
Typical ranges across the Jen-Ken lines we see most. Always confirm against your own rating plate.
Where to find the data tag on a Jen-Ken
Jen-Ken's data plate sits on the control box, usually near the digital controller on its glass fusing and multi-purpose models. Because Jen-Ken's AF3P and glass-fusing lines share similar cylindrical or rectangular chassis across several capacities, always confirm the model and serial from the plate rather than by chamber size alone.
Model series we supply
- AF3P 11/9
- AF3P 15/6

- Bonnie Glo BG24
What is specific about Jen-Ken
Jen-Ken is best known for glass fusing kilns, and the Chili Pepper and Bonnie Glo lines are built specifically for that work, while the AF3P series covers a broader multi-purpose range. Glass fusing schedules often involve long holds at or near peak temperature, which is a different duty cycle than a typical bisque or glaze firing and can wear elements differently over time, so tell us what the kiln is used for when ordering. Section count runs from four in the AF3P 11/9 up to six in the AF3P 15/6, Chili Pepper CP24, and Bonnie Glo BG24. We wind every element in-house from Kanthal A1 to the original resistance within ±2%, with a 48-hour standard lead time, and we always confirm supply voltage since 240V and 208V windings are not interchangeable.
How Jen-Ken elements typically fail
- Element wear from extended high-temperature holds typical of glass fusing schedules, distinct from the shorter peak times in ceramics firing
- Sagging wire in the groove, particularly in sections that see the most direct radiant load in a fusing cycle
- A single open section causing cold spots that show up as uneven fusing or incomplete melt across the glass
- Loose or corroded terminal connections at the control box, worth checking before assuming the coil itself has failed
Confirm before you order
Test the element before replacing it. A meaningful share of "dead element" calls turn out to be a thermostat, sequencer or limit switch, and the test takes ten minutes with a multimeter. Our resistance test tool tells you what your reading means.

Jen-Ken element questions
Do glass fusing kilns wear out elements faster than ceramics kilns?
Not always faster, but differently. Fusing schedules often hold at peak temperature for extended periods rather than the shorter dwell typical of a ceramics glaze firing, and that sustained heat can affect element life in a different way. Telling us the kiln is used for fusing helps us confirm the winding is right for that duty cycle.
My Bonnie Glo or Chili Pepper is showing an uneven melt across the glass. Could that be the element?
Yes, that is a common symptom of one failed or thinning element section. Since these are multi-section kilns, one dead coil creates a cold spot that shows up clearly in a fusing result even if the controller reads the target temperature at the thermocouple location.
Can you wind a replacement for an older Jen-Ken model that is no longer sold?
Yes, provided we can get the model and serial off the data plate, or failing that the coil gauge and groove length from the existing element. Jen-Ken has adjusted specs across production runs, so matching from the actual unit rather than a generic model name is the reliable way to do it.
