Professional Repair Time: 30-45 minutes
DIY Repair Time: 45-75 minutes
Difficulty Rating: Moderate-Advanced (3/5) — Requires intermediate electrical skills, understanding of 240V AC electrical systems, careful handling of high-voltage connections, range disassembly to access rear panel, multimeter testing, proper wire labeling and reconnection, attention to safety

CRITICAL SAFETY WARNING: This repair involves working with 240 volts AC electrical power and requires range disassembly to access the rear panel. Always turn off the circuit breaker and unplug the range before beginning work. Use a multimeter to verify power is off before touching any electrical components. If you are not comfortable working with high-voltage electrical systems or range disassembly, hire a qualified appliance repair technician.

1. Turn off the circuit breaker that supplies power to the range at the main electrical panel. This is critical for safety when working with 240V electrical systems.
2. Unplug the range from the electrical outlet (if accessible) to ensure complete power disconnection.
3. Verify power is off by attempting to turn on the range. The range should not respond and the display should be blank.
4. Use a multimeter to verify that no voltage is present at the range electrical terminal block. Set the multimeter to measure AC voltage (250V or higher range), and test between the two hot terminals (L1 and L2). The reading should be 0 volts. If any voltage is detected, do not proceed—verify the circuit breaker is off and the correct breaker has been identified.
5. Allow the cooktop to cool completely before working on it. The cooktop surface and elements can remain extremely hot for several hours after use. Use caution to avoid burns.
6. Pull the range away from the wall to provide access to the rear panel. You may need assistance to move the range safely.
7. Take multiple photos of the infinite switch installation, mounting position, wire connections, control knob position, and how the switch attaches to the rear panel before disassembly. Document from multiple angles. This is absolutely critical for proper reassembly. Use a camera or smartphone to capture high-quality images.
8. Remove the control knob from the front of the range by pulling it straight off the switch shaft. The knob typically friction-fits onto the shaft and should pull off with moderate force. If the knob is stuck, gently wiggle it while pulling.
9. Locate the rear panel access cover that provides access to the infinite switch (typically a metal panel on the rear of the range, secured with screws).
10. Remove the rear panel access cover by removing the mounting screws (typically 4-8 screws around the perimeter of the cover). Use a Phillips screwdriver or nut driver. Set the screws aside in a safe location.
11. Locate the infinite switch mounted on the rear panel or control panel behind where the control knob was located.
12. Take additional detailed photos of the wire connections to the infinite switch terminals before disconnecting. Note the wire colors and terminal positions for proper reconnection.
13. Label all wires with masking tape or labels indicating their terminal positions (e.g., "Terminal 1", "Terminal 2", "Element", "Power", "Ground") to ensure correct reconnection. This is critical for proper operation and safety.
14. Disconnect the wire harness from the infinite switch by removing the wire connectors from the switch terminals. Pull each connector straight off its terminal. Use needle-nose pliers to pull the connectors if they are tight—do not pull on the wires.
15. Remove the infinite switch mounting screws or bracket that secure the switch to the rear panel (typically 2-3 screws).
16. Carefully remove the old infinite switch from the rear panel and place it on a clean work surface with adequate space for inspection.
17. Inspect the old infinite switch for visible damage such as burned or pitted electrical contacts, cracked or melted housing, corroded or burned terminals, damaged cam mechanism, or broken mounting bracket. This confirms the diagnosis.
18. Test the old infinite switch with a multimeter to confirm failure. Set the multimeter to measure resistance (ohms) or continuity. With the switch in the "off" position, test between the power input terminal and the element output terminal—the reading should be infinite (open circuit). With the switch turned to various "on" positions, the contacts should cycle between open (infinite resistance) and closed (near zero resistance) as the bimetallic element heats and cools. If the contacts remain stuck open (infinite resistance in all positions), the switch has failed. If the contacts remain stuck closed (zero resistance continuously), the switch has failed.
19. Inspect the rear panel mounting area for damage, corrosion, or debris. Clean the mounting area if necessary using a dry cloth.
20. Inspect the wire harness connectors for corrosion, damage, or burned terminals. Clean or replace the connectors if necessary.
21. Unpack the new DG44-01005B infinite switch from its packaging. Handle carefully to avoid damaging the terminals or internal mechanism.
22. Verify the infinite switch specifications match the old switch: 5 wire terminal connections (critical—if your original switch has 7 connections, this part will not work), terminal configuration and positions, mounting hole locations, shaft length and diameter, voltage rating (240V AC), current rating (typically 15 amps).
23. Compare the new infinite switch to the old one to verify the dimensions, terminal positions, mounting holes, shaft configuration, and overall appearance match. Ensure you have the correct replacement part.
24. Inspect the new infinite switch for any damage or defects before installation. The housing should be intact with no visible cracks or damage. The terminals should be clean and undamaged. The shaft should rotate smoothly without binding.
25. Position the new infinite switch on the rear panel, aligning the mounting holes with the mounting points and ensuring the shaft protrudes through the control panel opening.
26. Install the mounting screws or bracket to secure the infinite switch to the rear panel. Tighten firmly but do not overtighten, which can crack the switch housing.
27. Verify the infinite switch is securely mounted and does not wobble or shift when gently pressed.
28. Reconnect the wire harness to the infinite switch by pushing the wire connectors onto the switch terminals. Refer to your detailed photos and wire labels to ensure correct connections. Push the connectors firmly onto the terminals until they are fully seated. Critical: Incorrect wire connections will cause the range to malfunction or create a fire hazard.
29. Verify all electrical connections are secure by gently tugging on each wire connector. The connectors should not pull off—they should be firmly seated.
30. Double-check all wire connections by comparing your installation to your detailed photos and wire labels. Verify each wire is connected to the correct terminal.
31. Reinstall the rear panel access cover by reversing the removal procedure. Install the mounting screws and tighten firmly.
32. Reinstall the control knob on the front of the range by pushing it onto the switch shaft until it is fully seated. Align any flat spots or keyways on the shaft and knob.
33. Push the range back toward the wall, leaving enough space to plug in the power cord.
34. Restore power by plugging in the range (if applicable) and turning on the circuit breaker.
35. Turn on the range and set the surface element control to a medium heat setting.
36. Verify the surface element heats properly by observing the element for 2-3 minutes. The element should begin glowing red or orange within 30-60 seconds, indicating proper heating.
37. Verify the element cycles on and off as controlled by the infinite switch. The element should glow brightly, then dim or go dark as the switch cycles off, then glow again as the switch cycles on. This cycling is normal operation.
38. Verify the element responds to control knob adjustments by turning the control knob to different heat settings. At higher settings, the element should stay on longer (higher duty cycle). At lower settings, the element should cycle off more frequently (lower duty cycle).
39. Turn the control knob to the off position and verify the element stops heating and cools down.
40. Test all heat settings from low to high to verify proper operation across the full range of adjustment.
41. Monitor the infinite switch for the first few uses to ensure it operates properly without overheating, burning smell, or other issues.

Safety Notes: Always turn off the circuit breaker and unplug the range before working on it to prevent electrical shock from 240V AC power. Use a multimeter to verify power is off before touching any electrical components. Label all wires before disconnecting to ensure correct reconnection. Critical: This switch has 5 wire terminal connections—if your original switch has 7 connections, this part will not work. Incorrect wire connections will cause the range to malfunction or create a fire hazard. This repair requires intermediate electrical and mechanical skills and careful attention to safety—if you are not comfortable working with high-voltage electrical systems or range disassembly, hire a qualified appliance repair technician.

1. Always verify power is off using a multimeter before touching any electrical components. Set the multimeter to measure AC voltage (250V or higher range) and test between the two hot terminals (L1 and L2) at the range electrical terminal block. The reading should be 0 volts. Never assume power is off based on the circuit breaker position alone—always verify with a multimeter. This is critical for preventing electrical shock from 240V AC power.
2. Label all wires before disconnecting them from the infinite switch. Use masking tape or adhesive labels to mark each wire with its terminal position. Take detailed photos of the wire connections before disconnecting to serve as a reference during reconnection. Incorrect wire connections will cause the range to malfunction, create a fire hazard, or cause electrical shock.
3. **Verify your original switch has 5 wire terminal connections before ordering the DG44-01005B.** This switch is designed for 5-terminal applications. If your original switch has 7 terminals, this part will NOT work as a replacement. Count the wire connections on your original switch before ordering to ensure compatibility.
4. Test the old infinite switch with a multimeter to confirm failure before replacement. Set the multimeter to measure resistance (ohms) or continuity. With the switch in the "off" position, test between the power input terminal and the element output terminal—the reading should be infinite (open circuit). With the switch turned to various "on" positions, the contacts should cycle between open and closed as the bimetallic element heats and cools. If the contacts remain stuck in one position, the switch has failed. This test confirms the diagnosis and prevents unnecessary replacement.
5. The infinite switch controls heat by cycling the element on and off, not by reducing voltage. At high heat settings, the element stays on 80-90% of the time (high duty cycle). At low heat settings, the element stays on only 10-20% of the time (low duty cycle). This cycling is normal operation—the element will glow brightly, then dim or go dark, then glow again. This is not a malfunction.
6. Inspect the wire harness connectors for corrosion, damage, or burned terminals before installing the new switch. Corroded or damaged connectors will cause poor electrical contact, overheating, and premature switch failure. Clean corroded terminals with a wire brush or sandpaper, or replace damaged connectors. Ensure all connections are clean and tight.
7. Do not overtighten the mounting screws when securing the switch to the rear panel. Overtightening can crack the switch housing or strip the mounting holes. Tighten the screws firmly but not excessively—tighten until the switch is snug and secure, then stop.
8. The infinite switch typically operates at 240V AC and controls elements rated from 1200W to 3600W (5-15 amps). Ensure the switch is rated for the element wattage in your range. Using an undersized switch will cause overheating and premature failure. The DG44-01005B is rated for typical Samsung range surface elements.
9. After installation, verify the element cycles properly at all heat settings. Test each heat setting from low to high. At low settings, the element should cycle off frequently (short on-time, long off-time). At high settings, the element should stay on most of the time (long on-time, short off-time). If the cycling pattern is incorrect, verify all wire connections are correct according to your photos and labels.
10. The infinite switch is a high-wear component that typically fails after 10-15 years of regular use. With average use (daily cooking), the switch typically lasts 12-15 years before failure. The electrical contacts wear from repeated arcing during switching. Replace the switch promptly when failure is detected to restore reliable surface element control. This repair is cost-effective compared to range replacement—the cost of infinite switch replacement ($80-140) is far less than the cost of a new range ($1,500-4,000+).
