If your electric water heater isn’t working properly, one of the first things you should check is the thermostat. The thermostat controls the temperature of the water in the heater, so if it’s not working right, the water won’t be heated to the proper temperature. Testing the thermostat is a relatively simple process that anyone can do.
- Unplug the water heater from the power source
- Test the thermostat with a multimeter to see if it is functioning properly
- If the thermostat is not working, replace it with a new one
- Plug the water heater back in and turn it on
- Adjust the thermostat to the desired temperature and let the water heater run for a few hours to test it out
Water Heater Not Heating? Thermostat Testing
How Do I Know If My Hot Water Heater Thermostat is Bad?
If your water heater isn’t heating water properly, it could be because the thermostat is bad. There are a few ways to test whether or not the thermostat is working properly.
One way is to check the temperature of the water coming out of the faucet.
If it’s not as hot as it should be, then the thermostat might be set too low and needs to be adjusted. Another way to test the thermostat is to use an infrared thermometer to measure the temperature of the water inside the tank. The ideal range for most water heaters is between 130°F and 140°F.
If you think your thermostat might be bad, you can also try bypassing it by connecting the two wires that go to it together. If this doesn’t solve the problem, then you’ll need to replace the thermostat.
How Do I Test My Electric Heater With a Multimeter?
If you’re unsure whether your electric heater is working properly, you can test it using a multimeter. First, make sure that the power is turned off to the heater. Then, set your multimeter to the Ohms setting and touch the probes to the two terminals on the heater.
If the reading is infinite, then the heater is working properly.
How Do You Test an Electric Water Heater With a Digital Multimeter?
If you’re like most people, you probably don’t think about your water heater very often. But when it stops working, it suddenly becomes the center of your attention. If your electric water heater isn’t heating water, there are a few things you can check before calling a professional.
One of them is testing the elements with a digital multimeter.
To test the elements, first make sure that the power is off to the water heater. Then remove the access panels and locate the two elements.
They will be screwed into threaded sockets in the tank.
Use your digital multimeter to test each element for continuity. To do this, touch one lead of the meter to each terminal of the element.
If there is continuity, the meter will beep or register a reading on its display. If there is no continuity, that means the element is defective and needs to be replaced.
Once you’ve determined which element is defective, replacing it is relatively easy.
Just unscrew the old element and screw in a new one in its place. Be sure to use caution when handling electrical components like these – always use gloves and take care not to drop anything into the tank!
How Do You Reset an Electric Water Heater Thermostat?
If your electric water heater is not working properly, it may be because the thermostat has gone bad. In this case, you will need to reset the thermostat. Here’s how:
First, turn off the power to the water heater at the breaker box. Then, remove the access panel from the side of the water heater. Locate the thermostat on the upper element.
It will have two wires going to it.
Carefully unscrew the wires from the terminals on the thermostat and remove it. Take the new thermostat and screw its wires onto the same terminals.
Be sure that they are tight so that they make good contact.
Put back on the access panel and turn on power to water heater at breaker box. Test for proper operation by turning on a hot water faucet in your home.

How to Test Water Heater Thermostat With Multimeter
If your water heater is having issues heating up water or if the water temperature is inconsistent, it may be a problem with the thermostat. You can test the thermostat with a multimeter to see if it’s working properly.
First, locate the thermostat on your water heater.
It will be a small knob or dial on the front or side of the unit. Once you’ve found it, turn off power to the water heater at your breaker box.
Next, use your multimeter to test for continuity between the two terminals on the thermostat.
If there is continuity, that means the thermostat is working properly and you don’t need to replace it. If there is no continuity, that means the thermostat needs to be replaced.
Once you’ve determined whether or not the thermostat needs to be replaced, you can follow these steps to do so:
1) Turn off power to the water heater at your breaker box.
2) Remove the old thermostat by unscrewing it from its housing. 3) Install the new thermostat by screwing it into place.
Conclusion
If your electric water heater isn’t working properly, one of the first things you should check is the thermostat. Testing a water heater thermostat is a relatively simple process that anyone can do.
To test your water heater’s thermostat, start by turning off the power to the unit at the breaker box.
Once the power is off, remove the access panel on the side of the unit so you can see the thermostats and heating elements. Locate the two wires that are connected to the top of the upper thermostat—these will be your “test” wires.
Next, use a multimeter to test for continuity between these two wires.
If there is continuity, this means that the upper thermostat is working properly and you can move on to testing the lower thermostat. If there is no continuity, however, this means thatthe upper thermostat needs to be replaced.
To testthe lower thermostat , simply followthe same steps as above but withthe two wires that are connectedto the bottom oftherather than those connectedto the top .
Again,if thereis continuity between these twowires thenyour lowerthermostatshouldbe finebut if not thenit needsto be replaced .
So there you have it—a quick and easy guide to testing your electric water heater’s thermostats!
