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, and if it’s not working correctly, the water may not be heated to the proper temperature. Testing the thermostat is a relatively simple process that can be done with a multimeter.
- Unplug the water heater from the power source
- Remove the access panel to the thermostat(s)
- Use a multimeter to test for continuity through the thermostat(s)
- If there is no continuity, then the thermostat is faulty and needs to be replaced
- If there is continuity, then test for resistance across the terminals of the thermostat(s)
- The resistance should be within a certain range depending on the temperature setting of the thermostat(s)
- If it is not within that range, then the thermostat is faulty and needs to be replaced
Water Heater Not Heating? Thermostat Testing
How Do I Know If the Thermostat is Bad on My Water Heater?
If your water heater is not working as efficiently as it used to, or if it isn’t providing enough hot water, it could be due to a faulty thermostat. There are a few ways you can test your thermostat to see if it is the cause of the problem.
One way to test your thermostat is to use an infrared thermometer.
Aim the thermometer at the water heater’s thermostat and check the reading. If the reading is lower than what it should be, then the thermostat may be defective and needs to be replaced.
Another way to test your thermostat is by feeling the outside of the water heater tank.
The tank should feel warm to the touch if the thermostat is working properly. If the tank feels cool, then that is an indication that the thermostat might be defective.
If you suspect that your water heater’s thermostat might be defective, it’s best to call a professional for help.
They will be able to properly diagnose the problem and make any necessary repairs.
How Do I Test My Electric Heater With a Multimeter?
If you’re troubleshooting your electric heater and want to test it with a multimeter, here’s what you need to do. First, make sure the heater is unplugged from the power source. Then, using your multimeter set to the ohms setting, touch one lead of the multimeter to each of the heater’s terminals.
If the reading on the multimeter is infinite, that means there’s no continuity and the heater is most likely defective.
How Do You Test an Electric Water Heater With a Digital Multimeter?
An electric water heater is a very useful appliance in many homes. They provide a constant supply of hot water, and are relatively low maintenance. However, like any other appliance, they can sometimes have problems.
One way to test an electric water heater is with a digital multimeter.
To test your electric water heater with a digital multimeter, you will need to:
1. Turn off the power to your water heater at the breaker box.
2. Unplug the unit from the wall outlet if it is plugged in.
3. Remove the access panel on the side of the unit so that you can access the wiring inside.
4. Set your multimeter to the Ohms setting, and touch one probe to each of the wires coming from the heating element (usually two black wires).
If there is continuity between these wires, then the heating element is likely fine. However, if there is no continuity, then the heating element needs to be replaced.
How Does an Electric Water Heater Thermostat Work?
An electric water heater thermostat is a device that helps to regulate the temperature of water in an electric water heater. There are two types of electric water heater thermostats: those with one element and those with two elements. One-element thermostats control only the top element in an electric water heater, while two-element thermostats control both the top and bottom elements.
How does a one-element thermostat work?
A one-element thermostat regulates the temperature of water by controlling the power to the top heating element. The heating element is turned on when the thermostat senses that the water in the tank has cooled below the setpoint temperature and turns off when it reaches that temperature.
This cycling of power to the heating element helps to maintain a consistentwater temperature.
How does a two-element thermostat work?
A two-element thermostat also regulates the temperature of water by controlling power to both heating elements—the top and bottom elements in an electric water heater.

How to Test Water Heater Thermostat With Multimeter
If your water heater isn’t working as efficiently as it used to, or if it’s not heating up at all, it might be time to test the thermostat. The thermostat is responsible for regulating the temperature of the water in the heater, so if it’s not working properly, your water heater won’t function correctly.
Luckily, testing the thermostat is a relatively simple process that you can do yourself with a multimeter.
All you need is a basic understanding of how to use a multimeter and some patience. With a little bit of time and effort, you can easily test your water heater thermostat and get it back up and running like new!
Conclusion
If your electric water heater isn’t working properly, it could be because the thermostat is faulty. You can test the thermostat to see if it’s the problem by following these steps:
1. First, turn off the power to the water heater at the breaker box.
2. Next, remove the access panel from the water heater so you can access the thermostat.
3. Use a multimeter to test for continuity through the thermostat. If there is no continuity, then the thermostat needs to be replaced.
4. If you find that the thermostat is working properly, then check other possible causes for why your water heater isn’t working, such as a tripped circuit breaker or a faulty heating element.
