On an electric water heater, only one heating element is on at a time.However, when a thermostat goes bad, it can create a problem where both heating elements run at the same time. This draws more electricity than the circuit can handle, causing the circuit breaker to trip.
Why would a hot water heater keep tripping the breaker?
Breaker Breaker
There are three possible explanations for a breaker being tripped by a hot water heater: water dripping on the electrical lines, a problem with the unit’s thermostat or a problem with the breaker. A malfunctioning thermostat is the most common cause. In this case, the thermostat should be replaced.
How can you tell if a heating element is bad in a water heater?
Touch a probe on the multitester to each screw on the element. If you get no reading, or a maximum reading, the element is bad. Elements do have some resistance, so a reading of 10-16 ohms is normal, with higher ohm readings for 3,500 watt elements and lower readings for 5,500 watt elements.
Can water cause a breaker to trip?
When extension cords are left outside over time, they can become frayed or cracked. Water from a sprinkler or rainstorm can make its way in, causing a short and making the circuit breaker trip.
How do you know when a breaker goes bad?
Key Indicators to Tell if You Have a Bad Circuit Breaker
- Breaker Doesn’t Stay in Reset Mode. It is possible the breaker is short-circuiting, but call an electrical professional to check it out.
- Burning smell.
- Hot to the touch.
- Visible damage to the box or outlets.
- Breaker trips frequently.
- Old Age.
Is there a breaker on a hot water heater?
You can cut off power to your hot water heater in either one of two ways: Locate your water tank and turn the power to it OFF by pulling the electrical plug out of the wall socket. Another way to turn the power off is to flip the circuit breaker (the breaker that’s labeled water heater) to the OFF position.
Can a thermostat trip a breaker?
The thermostat or furnace control is turning on a component or causing a load on the breaker that is causing the breaker to trip. There is actually a separation of the thermostat power circuit and the electrical circuit that powers the furnace.But is probably the instigator of the breaker tripping.
What happens when a heating element fails?
When an element fails it will usually “open” the electrical circuit and no further heating will take place. When this happens, the element simply appears to have stopped working.In some rare instances the element will “short-out” against the sheath which is the outer visible part of the surface unit.
How can you tell if a heating element is bad?
Inspect the metal wire coil for any breaks in the wire. If the wire is solid and has no breaks in it, the heating element should be good. If the wire has a break in it, the heating element is defective.
Why would a breaker randomly trip?
Generally, a circuit breaker will trip due to either a circuit shorted to ground or an overloaded circuit. If the circuit breaker trips as soon as the breaker is reset or when the system is turned on, the likely cause is a grounded circuit.
What can cause a breaker to trip?
A circuit breaker will usually trip when there is an electrical fault that could cause damage to the circuit. This is usually an excess of current, a power surge or a faulty component.
Why does my trip switch keep tripping?
Old, damaged, or faulty electrical appliances can leak extra current, and safety switches will trip when they detect the excess flow. With heavily used appliances, wear and tear is the main reason for performance issues, so you need to maintain them properly. If a switch goes off, first try resetting it.
How much does it cost to replace a water heater element?
Heating Element
If you have a problem with your element, it will probably cost between $200 and $300 to fix it. Most electric water heaters come with two heating elements.
Are upper and lower water heater elements the same?
Upper and lower heating elements are identical, and the temperature is regulated by the upper and lower thermostat and high limit device. Electric water heater elements can be different in size, but the most common is 12″ (300 mm).
Can a breaker be bad but not tripped?
Can a circuit breaker be bad without tripping? Yes, a circuit breaker can be bad without tripping. Failure can occur with the breaker set to “on”.
How do I test a circuit breaker that keeps tripping?
To test for circuit overload, the next time the breaker trips, go to the electrical panel and turn off all the switches in the affected area and unplug all appliances, lamps, and other devices. Flip the breaker back on and then turn on the switches and plug in/turn on devices one at a time.
Can you reset water heater with power on?
Somewhere on your electric water heater, you’ll find a reset button. It’s usually red and often located near the thermostat. It may also be hidden behind a removable metal panel on the unitand then behind some insulation.If your water heater now has power, you’re all set.
Can a bad capacitor trip a breaker?
Bad Capacitor
A weak or defective capacitor could trigger a tripped breaker if the compressor doesn’t receive adequate starting power. A failing start capacitor is a component that can be easily diagnosed and replaced by contacting your local HVAC contractor.
Will a water heater work with one element?
Yes, a water heater can still run if the bottom element quits.In most water heaters, the top heating element controls the thermostat and will still work even if the bottom element fails. So provided the top heating element is working, it can still produce some hot water even if the bottom heating element fails.
What causes a heating element to burn out?
If the coil gets too hot, it burns out. Among the conditions that can cause elevated temperatures are insufficient airflow in the element compartment, failure of safety devices and a power surge.
How long should a hot water cylinder element last?
Life expectancy of modern copper or stainless steel cylinders is 2040 years, but mains pressure glass-lined steel is shorter at 1220 years.
