Burner Stuck on High, Won’t Heat, or Knob Spins Freely Without Control — DG44-01005B Infinite Switch Failure Is the Most Common Cause
When the DG44-01005B surface element control switch fails, the radiant burner loses all heat regulation — it may lock on full high, produce no heat at all, or the control knob spins freely without changing the output. This is the genuine OEM infinite switch (energy regulator) for select Samsung electric ranges with glass-top radiant elements, and the active supersession for DG44-01005A, PER001-12D, 210728V, and related part numbers. Replacing it restores precise, reliable heat control across all settings.
⚠️ Symptoms of a Failed Surface Element Control Switch
- Burner stuck on high — won’t reduce heat regardless of knob position
- Burner produces no heat at any setting
- Control knob feels loose or spins freely without changing output
- Heat level won’t change — stuck at one setting
- Intermittent heating — element cycles on and off unpredictably
- Arcing, burning smell, or scorch marks at the control console
- Burner heats unevenly or takes much longer than normal to reach temperature
- Range trips breaker when the affected burner is activated

Samsung ranges may use different infinite switch variants for different element sizes or dual-element burners — the same model can have two or three different switch part numbers depending on which burner position you’re replacing. Confirm your model number AND the burner position (left front, right rear, etc.) before ordering. If the switch shows heat damage or melted spade terminals, inspect the wiring harness for insulation damage before installing the new switch — a damaged harness will destroy a new switch quickly.
⚙️ Installation Notes
- Skill Level: Intermediate — comfort with 240V appliance disassembly required
- Turn off the circuit breaker (240V) before beginning — do not rely on the range power switch alone
- Access the switch from the rear control panel or console depending on your model
- Photograph all wiring harness connections before disconnecting any terminals
- Note spade terminal sizes — loose connections cause arcing and switch failure
- Remove mounting screws, disconnect terminals, and install new switch in the same orientation
- Reconnect all terminals firmly; restore power and test all heat settings before reassembling the panel
- Verify model number AND burner position before ordering — switch specs vary by element size
