Parts for Jenn-Air CVEX4270B: 03 - Control Panel Parts

Replacement infinite-switch control knob that restores reliable heat selection on electric cooktops and ranges. Push-on design lets you set burner heat levels precisely and replaces cracked, faded, or missing knobs. What it does:

• Turns the infinite switch to select burner heat level and set cooking temperatures.
• Restores a secure grip and tactile detents when the original knob is cracked, worn, or missing.
• Helps when a knob spins, slips, or won't stay set on a chosen heat setting.
• Works with push-on style infinite switch shafts commonly used on electric ranges and cooktops.

• Always disconnect power to the appliance before servicing to avoid shock or injury.
• Typically installs by pulling the old knob straight off the control shaft and pushing the new knob onto the shaft until seated.
• Inspect the switch shaft for wear or damage; a stripped shaft may require replacing the infinite switch rather than the knob.
• If the knob is tight to remove, use a firm, even pull or a suitable knob-puller tool; avoid excessive prying that could damage the control panel.

A replacement control knob that restores safe, reliable selection of settings on the appliance. Fits the original shaft design to provide a secure, easy-turn interface for temperature and function selection. What it does:

The infinite switch is an OEM replacement part for Whirlpool cooktops. Located inside the panel it helps monitor temperature and functions through sensing heating elements and bake cycles. Precise cooking depends on its calibrated feedback.

Causes of a faulty cooktop interface switch include wire damage from heat exposure, excess baked-on residue insulating contacts, or repeated temperature fluctuations degrading components.

Symptoms include:

• Inability to preheat or maintain set cooking temperatures
• Failure to advance cycles or randomly turning off
• Error messages flashing on the control panel

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

A replacement gasket that seals the infinite (surface) control switch to the cooktop or console, helping keep moisture, grease and debris out of the switch area for cleaner operation and a better seal. What it does

• Seals the infinite switch to the panel to help prevent liquid and food intrusion into the switch housing.
• Cushions and stabilizes the switch for a firmer knob fit and reduced vibration.
• Helps protect the switch contacts from contamination that can cause intermittent control behavior.
• Use when the existing gasket is cracked, flattened, missing, or allowing spills into the controls.

• Disconnect power to the appliance before servicing to avoid shock or injury.
• Remove the control knob and access the infinite switch per your model's service instructions.
• Seat the gasket fully around the switch housing so it lies flat against the console; replace if damaged or compressed.
• Inspect the switch and wiring while replacing the gasket; replace the switch if there is visible damage.
