Roper Electric stove burner temperature is erratic
When your Roper electric stove burner temperature is erratic, the burner may be cycling unpredictably, jumping from too hot to too cool, or receiving power only intermittently. The most likely cause is a defective surface element switch, which can send inconsistent voltage to the surface element coil. If the same-size burner works normally when swapped, but the problem follows the control, replace the switch. When two or more burners have erratic temperatures, a failed relay in the surface element board is more likely. If only one burner is affected, test the element for continuous electrical continuity before condemning the board. A defective range control board or oven control board can also interrupt voltage to one or more heating elements, while a burned element receptacle and wire kit can cause intermittent contact at the element prongs. Inspect the receptacle, prongs, and wiring for heat damage or loose, burned connections. Disconnect power before testing or replacing parts, and use your wiring diagram when checking voltage. Enter your Roper model number to find the exact surface element switch, surface element board, control board, receptacle, or wire kit for your electric stove.
01 - Roper 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 - Roper 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 - Roper 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 - Roper 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 - Roper 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.
