Safe first steps, before the call. Nothing here needs a tool.
If you smell gas, a carbon monoxide alarm sounds, or anyone feels dizzy or sick: don’t touch any switch or plug, leave and get everyone out, then call 911 or the gas company from outside.
Smoke or flames: get everyone out and call 911.
No gas smell, smoke or flames? Turn the water heater’s gas control knob to OFF if it’s gas, or switch off its breaker if it’s electric.

Symptoms & causes
The primary symptom is a distinct burning odor emanating from or around your Samsung water heater, often described as electrical, plastic, or rubber burning. This smell typically indicates an electrical issue such as overheating wiring, a failing heating element, or a malfunctioning thermostat causing components to exceed their safe operating temperature. Dust accumulation on hot surfaces or a short circuit within the control board or terminal block can also produce this hazardous smell.
Tools & parts
You will need a multimeter to test for continuity and voltage, along with a non-contact voltage tester to ensure power is off. A wire brush or compressed air can help clean dust, while replacement Samsung heating elements or a new thermostat might be necessary. Basic hand tools like screwdrivers and wrenches are also essential for accessing and replacing components.
Safety first
Immediately shut off all power to the Samsung water heater at the main electrical breaker to prevent electrical shock and fire hazards. Also, turn off the cold water supply valve to the unit to prevent water leaks if components need to be removed. Always verify power is off with a voltage tester before touching any internal components, and be aware of potential scalding water if draining the tank.
When to call a pro
If the burning smell persists after cleaning and basic component checks, or if you observe visible charring on wiring or the control board, it's time to call a qualified technician. Complex electrical faults, such as a short circuit within the main power supply or a faulty internal wiring harness specific to Samsung models, require professional testing tools and expertise. Any signs of internal tank damage, such as leaks or sediment buildup affecting element performance, also necessitate a professional assessment to ensure safe and efficient operation.
