XPARTCO DG44-01002A Surface Element Infinite Switch

XPARTCO DG44-01002A Surface Element Infinite Switch The XPARTCO DG44-01002A is an aftermarket replacement dual element infinite switch (energy regulator) for Samsung electric ranges. This switch does two jobs at once: it regulates how much electrical current reaches its surface element, which is what lets you dial in a precise heat level rather than just on/off, and it also controls the "hot surface" indicator light associated with that burner, letting you know when the element is still hot after use. Over time, the internal contacts in this switch can wear, stick, or fail electrically. Because a single switch controls both functions, a failing switch can produce two very different-looking symptoms depending on which function is affected: the burner may stay stuck on high heat regardless of the dial setting, fail to produce any heat at all, or the hot surface indicator light may stay on for hours after the surface has completely cooled, even though the element itself tests fine. It directly replaces 2087510, MDSA-W21-SKM, MDSA-W888-UNM, MDSA-W888-UM, AP4337066, PS4240803, and EAP4240803. Quick Answer The XPARTCO DG44-01002A Surface Element Infinite Switch fixes Samsung electric ranges where a burner is stuck on high heat regardless of the dial setting, won't produce any heat at all, or the hot surface indicator light stays on for hours after the surface has cooled. Dual element design. Replaces 2087510, MDSA-W21-SKM, MDSA-W888-UNM, MDSA-W888-UM, AP4337066, PS4240803, EAP4240803. This switch controls both the element and its indicator light — if your indicator light won't turn off even though the burner is cool, this switch (not the element) is the cause. Common Problems This Part Fixes Burner stuck on high heat regardless of the dial setting Burner won't produce any heat at all Hot surface indicator light stays on for hours after the burner has completely cooled Inconsistent heating — burner doesn't hold the selected temperature level Unresponsive burner controls Burner that heats erratically rather than at a steady, selected level Cross Reference Information Part numbers can change over a product's lifecycle as manufacturers update designs or release new appliance models. For your convenience, we've included any known superseded, alternate, or cross-reference part numbers that match this item. Replaces Part Numbers This range surface element infinite switch directly replaces the following OEM and cross-reference part numbers: DG44-01002A, 2087510, , MDSA-W21-SKM, PS4240803, AP4337066, EAP4240803, ASM37999, PD00006793, 737534552513 If your part number is not listed above, contact our support team before ordering and we will verify compatibility. Compatibility This infinite switch is compatible with select Samsung electric ranges in the FCQ3, FE71, FER3, FTQ3, and NE59 series, including model numbers such as NE59J3420 and NE59J4310. Note: This is the switch, not the radiant heating element itself — the companion element is a separate part, DG47-00022A. If you're diagnosing a burner problem, it's worth testing both parts, since either one failing can cause similar symptoms. Always verify your full model number before ordering. Contact our support team with your model number if you're unsure. Key Features Aftermarket replacement dual element infinite switch (energy regulator) Controls both the surface element's heat output and its hot surface indicator light Resolves "stuck on high heat," "won't heat at all," and "indicator light stays on" symptoms caused by switch failure Direct drop-in replacement — matches the original mounting and wire connections Replaces 2087510, MDSA-W21-SKM, MDSA-W888-UNM, MDSA-W888-UM, AP4337066, PS4240803, and EAP4240803 Compatible with Samsung electric ranges in the FCQ3, FE71, FER3, FTQ3, and NE59 series Aftermarket replacement built to OEM-equivalent quality standards Straightforward DIY repair, typically 10 to 15 minutes Product Specifications Part Number XPDG44-01002A OEM Part Number DG44-01002A Part Type Range Surface Element Infinite Switch (Energy Regulator) Condition Aftermarket Replacement Brand Samsung Design Dual element Function Regulates surface element heat output; controls hot surface indicator light Related Part DG47-00022A radiant element (sold separately) Repair Difficulty Easy — 10 to 15 minutes Quantity 1 infinite switch Compatible Brand Samsung Installation Notes ⚠️ Unplug Range Before Starting — Photograph Wiring Before Disconnecting Disconnect power at the outlet or shut off the circuit breaker before beginning. Wear work gloves. Access is typically from the rear of the control panel or the underside of the cooktop, depending on your model. Photograph the wiring connections on the old switch before disconnecting anything, since correct wire placement is essential for the switch to control the right burner and indicator light. Remove the screws securing the old switch, gently pry it out, and mark or note each wire's position for reference. Disconnect the wires from the old switch and remove it fully. Install the new DG44-01002A in the same position, reconnect each wire to its original terminal exactly as photographed, and secure the mounting screws. Restore power and test the burner across its full range of settings, confirming both the heat output and the indicator light behave correctly. Tools needed: screwdriver, pliers, pen or pencil for marking wires, work gloves. Frequently Asked Questions My hot surface light stays on for hours even though the burner has cooled down. Is this the switch? Yes. This is a documented symptom specific to this switch, since it controls both the surface element and its indicator light together. If the light isn't going out even though the surface itself is cool to the touch, the switch — not the element — is the correct part to replace. My burner is stuck on high heat no matter what setting I choose. Is that the switch or the element? It could be either, so it's worth testing both with a multimeter before replacing. Test the radiant element first — it should read between 0 and 120 ohms if it's working correctly. Then test the infinite switch itself: remove it, connect a multimeter probe to each prong, and turn the switch to an on position. No continuity indicates the switch is the issue. Several customers have confirmed this exact symptom by swapping switches between two burners and watching the problem follow the switch, which is also a reliable way to isolate the cause if you have two dual-element burners. Should I replace the element (DG47-00022A) at the same time? Not necessarily, but it's worth testing both parts if you're not sure which one has failed, since a bad element and a bad switch can produce overlapping symptoms. If your multimeter tests confirm only the switch has failed, replacing just this part is sufficient. Is this an OEM or aftermarket part? This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Samsung OEM part, but is manufactured to match the dual-element switching function, wire terminal configuration, and mounting design of the original DG44-01002A infinite switch used in compatible Samsung electric ranges.
