Left Front Dual Element Not Heating on Samsung Range? Here’s What to Do

Is the left front dual burner on your Samsung electric range not heating up? Don’t worry. This is a common issue, and you can often fix it yourself without needing to call in a technician. With a few tools, some basic precautions, and a bit of time, you can get your range working again.

Common Reasons the Element Stops Working

Before replacing anything, it’s good to know the usual causes behind a faulty dual burner:

• Burned-out element: Heating elements can wear out over time and stop working completely.
• Failed infinite switch: This controls power flow to the burner and can prevent it from turning on.
• Wiring issues: Loose, damaged, or corroded wires may interrupt power to the burner.
• Faulty burner socket: Poor contact between the element and socket can cause intermittent or no heating.
• Control board issues: In rare cases, the problem may come from the electronic control board not sending power correctly.

What You’ll Need

• Phillips head screwdriver
• Flathead screwdriver
• Multimeter

Safety First

Before starting any repair, it’s important to keep safety in mind. Working with appliances involves risk, so preparation is key:

• Cut power: Unplug the range or switch off the circuit breaker. This removes the risk of electric shock.
• Let it cool: If the cooktop was recently used, give it time to cool completely before starting any work.
• Stay organized: Work in a clean, well-lit space. Keep children and pets away from the area.
• Keep everything dry: Do not handle internal parts with wet hands or in a damp space.
• Use protection: Wear insulated gloves. Safety glasses or a dust mask can help when dealing with debris or dust.
• Document connections: Take photos or write notes before disconnecting wires. This helps when it’s time to reassemble.
• Handle parts carefully: Internal components can be sharp or fragile, so be gentle when removing or adjusting them.
• Work patiently: Take your time to avoid mistakes or injuries.
• Avoid testing live voltage: If you are not confident using a multimeter on a live circuit, stick to testing with the power off.

How to Troubleshoot a Samsung Electric Range

Follow these steps to diagnose and fix common issues with your electric Samsung range, including problems with heating elements, wiring, and the control switch.

1. Test the Dual Infinite Switch

1. Disconnect power to the range by unplugging it or turning off the circuit breaker.
2. Remove the rear panel on the back of the control panel to access the dual infinite switch.
3. Plug the range back in and power it on.
4. Set your multimeter to Volts AC mode.
5. Place the multimeter probes on the P1 (double red wires) and P2 (double black wires) terminals.
6. Check for 240 Volts AC at these terminals.
7. Turn the infinite switch to activate the inner element.
8. Test for 240 VAC between terminal 4 (yellow and violet with gray) and terminal 2 (blue wire).
9. Turn the infinite switch to activate both the inner and outer elements.
10. Test for 240 VAC between terminal 4A (violet wire) and terminal 2 (blue wire).
11. If the infinite switch fails any of these tests, replace it.
12. If it passes all tests, continue to the next section.

2. Inspect the Wiring Harness

13. Disconnect power to the range.
14. Examine the wiring between the dual infinite switch and the dual element.
15. Look for frayed wires, burn marks, broken wires, or damaged insulation.
16. Replace any damaged wiring or insulation.
17. If the wiring is intact, move to the next section.

3. Test the Heating Elements

18. Keep the range disconnected from power.
19. Set the multimeter to continuity mode.
20. Test for continuity between connector 1B (black wire) and 2B (yellow wire) with the element in the off position.
21. Test for continuity again with the element in the on position.
22. A beep from the meter confirms continuity.
23. Switch the multimeter to resistance mode (Ω).
24. Test the resistance of the inner element from 2A (gray wire) to terminal A (blue wire).
25. Check that the resistance is between 45 and 55 Ohms.
26. Test the resistance of the outer element from 2A (gray wire) to terminal B (orange wire).
27. Check that the resistance is between 42 and 48 Ohms.
28. If any reading is out of range, replace the affected element.
29. If the elements pass all tests, continue to the next section.

4. Check Voltage at the Elements

30. Plug the range back in and turn it on.
31. Set the multimeter to Volts AC mode.
32. Test for 240 VAC between 2A (gray wire) and terminal A (blue wire) for the inner element.
33. Test for 240 VAC between 2A (gray wire) and terminal B (orange wire) for the outer element.
34. If 240 VAC is present but the element does not heat, replace the dual element.

What to Do After the Repair

Once you’ve replaced or repaired the faulty part, these follow-up tips help bring your range back into full use safely:

• Double-check all connections before restoring power to the unit.
• Plug the range back in or turn on the breaker after confirming everything is reassembled properly.
• Test the burner on both heat settings to make sure both the inner and outer elements are heating correctly.
• Listen for clicking or unusual noises that might indicate a loose connection or damaged part.
• Watch for smoke or burning smells during the first test run, and turn off the power immediately if anything seems off.
• Reinstall any screws, brackets, or covers that were removed during the repair.
• Keep the work area clean to avoid introducing debris into the cooktop or vents.

To Recap

A burner that won’t heat can seem like a big problem, but often, the fix is easier than expected. If the left front dual element on your Samsung range stops working, the issue might come from something simple—like a bad switch, loose wiring, or a worn-out element. You don’t need fancy tools or expert skills to sort this out. Just follow the steps, stay patient, and take it one part at a time.
