In the next five minutes
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 smell of burning plastic, rubber, or electrical components emanating from your Frigidaire water heater often indicates an internal electrical fault or overheating. This could be due to a failing heating element drawing excessive current, damaged wiring insulation, or a malfunctioning thermostat causing the unit to overheat. Sediment buildup at the bottom of the tank can also cause elements to work harder and overheat, leading to a burning smell.
Tools & parts
For tests, you'll need a multimeter to test continuity and voltage, and a non-contact voltage tester for initial safety checks. Replacement parts might include a new Frigidaire heating element, a thermostat, or wiring connectors. You may also need basic hand tools like screwdrivers, pliers, and a socket wrench set for accessing internal components.
Safety first
Immediately shut off the electrical power to the Frigidaire water heater at the circuit breaker to prevent electrocution or further damage. Turn off the cold water supply valve to the unit to prevent water leaks if components need to be removed or replaced. Be aware of potential scalding hot water if draining the tank, and always ensure the unit is completely de-energized before touching any internal wiring.
When to call a pro
If the burning smell persists after basic troubleshooting or if you observe visible arcing or smoke, it's crucial to call a qualified technician. Complex electrical issues, such as a short circuit within the main wiring harness or a faulty control board, require specialized testing tools and expertise. Additionally, if the pressure relief valve is actively discharging or the tank itself shows signs of bulging or leaking, immediate professional intervention is necessary to prevent a catastrophic failure.
Questions people ask
Why does my Frigidaire water heater smell like burning plastic?
This often indicates an electrical issue, such as overheating wiring insulation or a failing heating element. The plastic smell is typically from the insulation melting due to excessive heat or a short circuit.
Is it safe to use my Frigidaire water heater if it smells like burning?
No, it is not safe. A burning smell is a serious warning sign of an electrical fault or overheating, which could lead to fire or further damage if ignored.
Can sediment cause a burning smell in my Frigidaire water heater?
Yes, sediment buildup at the bottom of the tank can cause heating elements to work harder and overheat. This excessive heat can scorch the sediment or surrounding components, leading to a burning odor.
