Americana Electric stove burner temperature is erratic

When your Americana electric stove burner temperature is erratic, the surface element may be receiving inconsistent voltage. The most likely cause is a defective surface element switch, especially if only one burner changes temperature unexpectedly. If two or more burners have erratic performance, the surface element board may have a failed relay that cannot regulate power correctly. A range or cooktop control board, including the oven control board on some models, can also send intermittent voltage to the heating element. For a single electric stove burner temperature problem, test the surface element for continuous electrical continuity. If you have a coil burner, inspect the element receptacle and wire kit for burnt contacts or damaged prongs. Loose or burnt wire connections near the heating element are less common but can also interrupt power. Always disconnect power before inspecting parts, and use a multimeter only if you are comfortable following the wiring diagram. Replace a defective surface element switch, surface element board, control board, element receptacle, or wire as needed. Enter your Americana range model number to find the exact replacement part for your specific stove and confirm fit.

01 - Americana 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 - Americana 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 - Americana 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.
Highly Likely

04 - Americana 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 - Americana 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.
