If your water heater isn’t providing enough hot water, it may be because the heating elements need to be replaced. You can test the heating elements to see if they are functioning properly. First, locate the two screws that hold the element in place.
Then, using a multimeter set to ohms, touch one lead of the multimeter to each screw. If the reading is infinite, then the element is working correctly. If you get a low reading or no reading at all, then the element needs to be replaced.
- Unplug the hot water heater from the wall outlet
- Remove the access panel on the side of the hot water heater
- Locate the two elements inside the tank and test each one with a multimeter set to ohms mode
- If an element is not functioning properly, it will show a high resistance reading on the multimeter
- Replace any elements that are not working properly and reassemble the hot water heater
How To Test A Water Heater Element
How Do I Know If My Hot Water Heater Element is Bad?
If your water heater isn’t heating up as well as it used to, or if it’s taking longer for the water to get hot, it’s possible that the heating element is beginning to fail. There are a few ways to test whether or not this is the case.
One way is to simply feel the outside of the tank.
If it’s warm to the touch, that means that heat is escaping and the element may be failing. Another way is to check the circuit breaker or fuse box; if there’s no power going to the water heater, that could be an indication that the element needs replacing.
If you have an electric water heater, you can also test the element itself with a multimeter.
First, make sure that there is no power going to the unit by flipping off the switch at your breaker box. Then remove one of the wires (or unscrew a terminal nut) from each end of the element and touch one lead of your multimeter to each exposed end of wire. If you see a reading on your meter, then congratulations – your element is still good!
How Do You Tell If Both Elements are Working in Hot Water Heater?
If your home has a hot water heater, it’s important to know how to tell if both elements are working. Otherwise, you may not be getting enough hot water, or worse, your unit could overheat and become a fire hazard.
Here are a few things to look for:
1. Check the thermostat. If it’s set too low, the element won’t heat the water sufficiently. Conversely, if it’s set too high, the element could overheat and start a fire.
The ideal setting is usually between 120-140 degrees Fahrenheit.
2. Listen for strange noises coming from the unit. If you hear sizzling or popping sounds, that could indicate that one of the elements is failing and needs to be replaced immediately.
3. Feel the outside of the unit. If it’s unusually hot to the touch, that means both elements are probably working overtime to try and heat the water inside (this is often caused by a faulty thermostat). This situation isn’t safe and should be addressed as soon as possible.
4. Check your hot water supply lines leading into and out of the unit.
How Do You Test a Water Heater Element?
If your water heater is having trouble heating up water, or if it’s taking longer than usual for the water to get hot, you may need to test the element. Here’s how:
First, make sure that the power is turned off to the water heater.
Then, remove the access panel so that you can see the elements. There will be two screws holding it in place; remove these and set the panel aside.
Now, use a multimeter to test each element for continuity.
To do this, touch one lead of the multimeter to one terminal of the element, and then touch the other lead of the multimeter to the other terminal of the element. If there is continuity, then you’ll see a reading on the multimeter; if there isn’t continuity, then there will be no reading.
Once you’ve tested both elements and determined which one is not functioning properly, you can replace it with a new one.
Be sure to turn off the power before removing and replacing any elements!
How Do You Test a Heating Element With a Multimeter?
If you’re troubleshooting a dryer that isn’t heating, one of the first places you should check is the heating element. With a multimeter, you can test whether the element is working and determine if it’s the source of the problem.
To test the heating element, start by disconnecting the dryer from power.
Then remove the back panel so you can access the element. Once you have access, use your multimeter to test for continuity across the terminals of the heating element. If there is continuity, then the element is working and not likely to be the source of your problem.
If there is no continuity, then chances are good that your heating element needs to be replaced.

How to Test Water Heater Element Without Multimeter
If your water heater is taking longer than usual to heat up, or if the water isn’t as hot as it used to be, then it’s possible that the heating element needs to be replaced. But how can you test the element without a multimeter?
fortunately, there is a way.
First, make sure that the power to the water heater is turned off. Then, remove one of the screws that hold the element in place and carefully pull it out. Be careful not to touch any of the wires with your bare hands.
Once you have removed the element, use a continuity tester or a multimeter set to ohms mode to test it. The resistance should be between 10 and 20 ohms. If it’s outside of this range, then the element needs to be replaced.
Conclusion
If your hot water heater is not working as efficiently as it used to, you may need to test the elements. Follow these steps to test hot water heater elements:
1. Shut off power to the unit and remove the access panel.
2. Use a multimeter to test continuity between the element terminals. If there is no continuity, then the element needs to be replaced.
3. If there is continuity, then use a voltage tester to check for voltage at the element terminals.
If there is no voltage, then check for a tripped circuit breaker or blown fuse.
4. If there is voltage at the element terminals, then use an ohmmeter to measure resistance across the element. The resistance should be within 10% of the manufacturer’s specifications for that particular element.
If it is not, then the element needs to be replaced.
