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.
No gas smell? Turn the water heater’s gas control knob to OFF if it’s gas, or switch off its breaker if it’s electric.
Take a photo of the tank, the floor and its label, without opening anything.
Everything else about this problem
Is it an emergency?
Is a Kenmore water heater that isn't working an emergency?
Rarely an emergency. Check power first: the plug, the breaker and any GFCI outlet. Stop and call a pro if it smells like burning, trips the breaker again, or runs on gas and you smell gas.
Symptoms & causes
When a Kenmore water heater is not working at all, common symptoms include a complete lack of hot water, no indicator lights, and no operational sounds from the unit. For electric models, this often points to an electrical issue such as a tripped circuit breaker, a failed upper thermostat, or a faulty heating element. Gas models might suffer from a pilot light outage, a malfunctioning thermocouple, or a problem with the gas control valve preventing ignition.
Tools & parts
You will need a multimeter to test for voltage and continuity in electrical components. A basic screwdriver set is essential for removing access panels. For potential replacements, a Kenmore-compatible upper thermostat and a lower thermostat may be needed.
Safety first
Always begin by shutting off the electrical power to the water heater at the main circuit breaker or turning off the gas supply valve for gas models. Use a multimeter to confirm that no voltage is present before touching any electrical components to prevent severe electrical shock. Be cautious of scalding hot water if draining the tank, and immediately address any gas odors by evacuating the area and contacting emergency services.
When to call a pro
If your Kenmore electric water heater repeatedly trips the main circuit breaker after being reset, this indicates a severe short in a heating element or wiring that requires professional testing. For gas models, if you smell gas but the pilot light won't stay lit after multiple attempts, or if the gas control valve appears faulty, a licensed technician is necessary. Any signs of water leaking from the tank itself, rather than connections, typically means the tank has failed internally and needs professional replacement.
Questions people ask
Why did my Kenmore electric water heater suddenly stop working?
It often indicates a tripped circuit breaker or a failed upper thermostat, which acts as a safety cutoff. Overheating or a short in a heating element can cause these components to fail.
Can I reset my Kenmore water heater myself?
Yes, for electric models, you can try resetting the red button on the upper thermostat after turning off the power. For gas models, you might need to relight the pilot light following instructions on the unit.
How do I know if a heating element is bad on my electric Kenmore?
You can test the heating elements for continuity with a multimeter after disconnecting power and wires. A reading of infinite resistance or a short to ground indicates a faulty element.
