Jenn Air Electric stove burner temperature is erratic
Is your Jenn Air electric stove burner temperature erratic? A surface element switch normally cycles power on and off to regulate temperature; erratic behavior suggests a defective switch. The most likely cause is a faulty surface element switch, which can cause one burner to cycle unpredictably even when the coil or radiant surface element is good. If two or more burners have erratic temperatures, the surface element board may have a failed relay that is interrupting power. A defective range control board or oven control board can also send voltage intermittently when the control knob or touchpad calls for heat. If only one burner is affected, switch it with another element of the same size. If the problem follows the element, test or replace the coil or radiant surface element. If it stays in place, inspect the element receptacle and wire kit for burned contacts, damaged prongs, or a loose or burnt wire connection. Disconnect power before inspecting or testing electrical parts, and use a multimeter only if you are comfortable following the wiring diagram. Enter your Jenn Air range model number to find the exact surface element switch, element receptacle, control board, or other replacement part that fits your electric stove.
01 - Jenn Air Range/Stove/Oven Surface Element Switch
The surface element switch sends voltage to the surface element coil. If the switch is defective, the surface element may only receive intermittent voltage resulting in erratic temperature changes. If there is another element of the same size on the stove, try switching the elements. If the surface element still only works intermittently, the surface element switch is likely defective. The surface element switch cannot be tested or repaired—if you suspect the switch is defective, replace it.

02 - Jenn Air Range/Stove/Oven Surface Element Board
The surface element board has relays that regulate the power supply to the burners. If one or more of the relays fails, the surface element may only work intermittently, resulting in erratic temperature changes. If two or more burners have erratic performance at the same time, this indicates that the surface element board is likely at fault. If only one surface element is erratic, use a multimeter to test the element for electrical continuity. If the surface element has continuity at all times, the surface element board might be defective.

03 - Jenn Air Range/Stove/Oven Control Board
A range or cooktop's control board will send voltage to a stovetop heating element when the element's control knob or touchpad button is set to the “on” position. If the control board is defective, the voltage may not be sent to the heating element or only sent intermittently resulting in erratic operation. You can inspect the board for signs of damage or a shorted component. You can also use a multimeter to test for voltage reaching the heating element or elements after reviewing the appliance's wiring diagram.

04 - Jenn Air Range/Stove/Oven Oven Control Board
A range or cooktop's control board will send voltage to a stovetop heating element when the element's control knob or touchpad button is set to the “on” position. If the control board is defective, the voltage may not be sent to the heating element or only sent intermittently resulting in erratic operation. You can inspect the board for signs of damage or a shorted component. You can also use a multimeter to test for voltage reaching the heating element or elements after reviewing the appliance's wiring diagram.
Highly Likely
05 - Jenn Air Range/Stove/Oven Element Receptacle and Wire Kit
The surface element plugs onto a receptacle. Over time, the contacts in the receptacle can burn out. If the receptacle contacts burn out, the surface element may only receive power intermittently or not at all. To determine if the element receptacle has failed, inspect the receptacle contacts. If the contacts are visibly burnt or damaged, replace the element receptacle. In addition, examine the element prongs for signs of burning. If the prongs are burnt, replace both the element and element receptacle.
Common
06 - Loose or Burnt Wire Connection
These wires commonly burn out near the heating element. To determine if a wire has burned out, inspect the wires leading to the element. If a wire is burned out, it will often be visibly burnt.
