Whether your geyser is electric or gas, a malfunctioning thermostat can cause your water to be too hot or too cold. Fortunately, there are a few simple ways to check your thermostat and ensure it is working as it should.
The thermostat can be accessed by opening up the front of your water tank. Usually, this requires the use of a small screwdriver, but some models are held in place by a special bracket. If your thermostat is too damaged to be repaired, you may need to replace it. Using a screwdriver or a pair of needle-nose pliers, you can remove the wires.
Luckily, most thermostats are interchangeable, so you should be able to find a replacement that fits your model. For best results, it helps to find a replacement that is the same type as your old one. This will ensure that you get the most out of your new unit.
The thermostat is the brains of your water heater, so you may want to test its abilities by making it do a few things. First, it should be able to tell you when it is time to turn off your element. It should also be able to tell you when the water is hot enough to turn on your element. You may also want to test its capabilities by resetting it. If you do, you may find that your problem is solved.
In fact, most thermostats are capable of doing many more tasks than just turning off your element. Using a multimeter to test for continuity is one way to make sure your thermostat is working properly. When you are testing, you should look for the following: a) a high temperature cutoff that has been tripped; b) a circuit breaker that has been tripped; c) a multi-function button; and d) a red button that has been tripped.
To test the multi-function button, look for the red button on the side of the thermostat. If you cannot find it, you may need to purchase a replacement. A video explains the functionality of the multi-function button.
The high-temperature cutoff is usually located just above the thermostat, and is a good indicator of how the thermostat is doing. If it is tripped, you may want to consider replacing the upper thermostat. If the thermostat is faulty, it will not be able to supply enough voltage to the lower thermostat. It may also be tripped by a faulty wiring connection.
Using a multimeter to test the functions of a thermostat is not for the faint of heart. However, it is the most cost-effective way to fix your water heater. By doing so, you will be able to see what is wrong with it and have an idea of what you need to do to fix it.
For instance, the multi-function button may be the only way to get the temperature of your water hot enough to turn on your heating element. It is a small gadget that is not easily overlooked, and it is probably the easiest to replace.
