Jenn-Air JES1450FS1 electric slide-in range Parts

Jenn-Air ovens come in gas, electric, and dual-fuel configurations, depending on the model. Your JES1450FS1 is an electric range, so its oven uses electric heating elements for baking and broiling.

• Electric range (like JES1450FS1): electric bake and broil elements heat the oven
• Gas range: a gas burner heats the oven cavity
• Dual-fuel range: gas cooktop with an electric oven

Use these checks to confirm whether a Jenn-Air oven is gas or electric:

• Model number label: usually inside the oven frame or storage drawer area
• Power connection: electric ranges typically use a heavy 240V cord/terminal block; gas ranges use a standard outlet for controls plus a gas line
• Oven heat source: electric ovens use visible heating elements; gas ovens use a burner and igniter system
• Cooktop clues: radiant glass-top elements are electric; sealed burners indicate gas

On this model, electric-oven parts are a strong indicator of the oven type:

Gas vs. electric affects installation requirements, troubleshooting steps, and which replacement parts fit (for example, an electric bake element vs. a gas igniter). Matching parts to the exact model number prevents ordering the wrong component.

Common problems we see with Jenn-Air electric ranges like model JES1450FS1 include an oven that will not heat or heats unevenly, surface elements that do not turn on or cycle correctly, and control or display issues. Many symptoms trace back to a failed heating element, a bad infinite switch, or a loose power connection.

• Oven not heating: failed bake element, wiring issue, or control problem (start by inspecting the bake element W10779716).
• Uneven baking or slow preheat: weakened bake element, temperature sensor drift, or poor door seal.
• One surface burner not working: failed radiant element (see range radiant surface element W11171119) or a bad burner control switch.
• Burner stuck on high or won’t change heat: failed infinite switch (common on electric cooktops).
• Display or keypad not responding: keypad or console-related failure, or a power reset issue.

1. Reset power: turn the range breaker off for 1 minute, then back on.
2. Confirm proper power supply: electric ranges typically need 240 VAC; a partial power loss can leave lights working but heating dead.
3. Look for visible damage:
   • blistering or breaks on the bake element
   • burned wiring at the rear connection area
   • a surface element that shows hot spots or does not glow evenly
4. Test heating performance: if broil works but bake does not, the bake element is the top suspect.

Heating and control problems can look similar, but the right first check saves time and prevents replacing good parts. For example, a loose connection at the terminal block can mimic a failed oven element.

The model number for your Jenn-Air range is printed on the appliance’s rating label. On most slide-in and freestanding electric ranges like JES1450FS1, that label is typically found around the oven door frame or on the storage or warming drawer frame.

Check these common label locations first:

• Open the oven door; look along the left or right door frame (front frame of the oven cavity)
• Look along the bottom edge of the oven door opening
• Pull out the storage drawer; check the frame behind the drawer front
• If your model has a warming drawer, check the frame around that drawer opening
• Look on the back panel near the power cord connection area (less common, but possible)

Copy the information exactly as shown on the label:

• Model number (example: JES1450FS1)
• Serial number (helps confirm production run and correct revisions)
• Any suffixes after the model number (they can affect part fit)

Parts like a surface element switch, control board, or oven component can vary by revision. Using the exact model number helps us match the correct diagrams and parts for your range.

• Use a flashlight; labels are often low and hard to read
• Wipe dust or grease gently; do not scrub the label
• Take a clear photo so you can zoom in
• Match the model number exactly when ordering parts
