Hotpoint Electric Range Burner Not Heating Up:... | appliancefaults.com

Technical Background:

Hotpoint electric ranges use a Main Control Unit (MCU) to manage the operation of the surface burners. The MCU receives signals from the surface element switches (infinite switches) indicating the desired heat level. It then regulates the voltage supplied to the burner elements. Each burner element is connected to the range's wiring through a receptacle. Burner elements are resistive loads, and resistance is measured in Ohms.

Symptoms:

US homeowners are reporting that one or more of their Hotpoint electric range surface burners are not heating up at all, or are only getting slightly warm, despite being turned on. Some report that the other burners are working normally.

Possible Causes:

Faulty burner element
Defective surface element switch (infinite switch)
Burned-out receptacle connecting the burner element
Wiring issues within the range
Malfunctioning electronic range control (ERC) or main control unit (MCU)
Tripped breaker in the breaker panel

Solution:

1

Disconnect power to the range by turning off the appropriate breaker in the breaker panel. Verify power is off with a non-contact voltage tester.
2

Remove the burner grate and the suspected faulty surface element.
3

Visually inspect the burner element for any signs of damage, such as cracks, blisters, or burns. If damaged, replace the element.
4

Test the burner element for continuity using a multimeter. Set the multimeter to the ohms setting. Place one probe on each terminal of the burner element. A reading of approximately 20-50 ohms indicates a good element. An open circuit (OL) indicates a failed element requiring replacement.
5

If the element tests good, inspect the surface element switch (infinite switch). Disconnect the wires from the switch and test for continuity between the terminals in each switch position. Refer to the range's wiring diagram for the correct terminal combinations. Replace the switch if it fails the continuity test.
6

Inspect the burner receptacle for any signs of burning or damage. Use a multimeter to test for 240V AC at the receptacle terminals when the breaker is on and the switch is in the high position (exercise extreme caution!). No voltage indicates a wiring issue or a faulty MCU.
7

If all other components test good, suspect a faulty ERC/MCU. Replacement of the ERC/MCU may require licensed technician assistance.

Safety Warning:

Always disconnect power to the range at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental re-energizing of the circuit. Electric ranges operate at 240V AC, which can cause serious injury or death. Exercise extreme caution when working with electrical components.

Prevention:

• Avoid using oversized cookware that extends beyond the burner element, as this can cause uneven heating and element burnout.
• Clean spills from the cooktop promptly to prevent them from burning onto the elements or receptacles.
• Do not use abrasive cleaners on the cooktop, as they can damage the surface and potentially the burner elements.

Expert Tip:

Many Hotpoint ranges have a hidden service mode. Typically, pressing and holding two buttons simultaneously (often Bake and Broil) for 3-5 seconds will activate the service mode, allowing you to run diagnostic tests and view error codes. Refer to your range's service manual for specific instructions.

Frequently Asked Questions

•How do I access the surface element switch (infinite switch) on my Hotpoint range?

Typically, you'll need to remove the cooktop to access the surface element switches. This usually involves removing screws located around the perimeter of the cooktop or under the burner grates. Exercise caution when lifting the cooktop, as wires are still connected. Refer to your range's service manual for specific disassembly instructions.

•Where can I find a wiring diagram for my Hotpoint range?

The wiring diagram is often located on a sticker attached to the back of the range or inside the control panel. You can also search online using your range's model number to find a digital copy of the wiring diagram. A repair technician will almost always have this information if you cannot locate the original.

•What type of multimeter should I use for testing the burner element and switch?

A standard digital multimeter (DMM) with voltage, current, and resistance measurement capabilities is sufficient. Ensure the multimeter is rated for AC voltage up to at least 250V. A multimeter with an auto-ranging feature is helpful but not essential.
