10 Signs That Water Heater Thermostat Isn’t Working

Have you ever anticipated a relaxing hot bath only to be met with icy cold water? Or, maybe you needed a cold shower on a hot day or after a demanding workout and all you got was lukewarm water coming out. These are frustrating and jarring experiences that can lay best laid plans to waste or even ruin your entire day. 

While several factors could be at play, the culprit is often a malfunctioning water heater and specifically the thermostat. Identifying the signs of a faulty thermostat can help you troubleshoot the issue and opt for a professional water heater installation in Riverside to get your hot or cold water flowing again.

Identifying the signs early on can help prevent a full-blown water heater breakdown. If you suspect that your water heater thermostat is not working, it’s wise to get in touch with specialists to diagnose and fix the problem. Attempting to repair it yourself without the necessary experience, equipment, and know-how could potentially lead to more significant issues, including damage to your water heater or serious personal injury. Stay safe, and let the experts handle the heavy lifting.

Be on the lookout for these ten signs that indicate your water heater thermostat may not be working as it should:

1. Inconsistent water temperature

If you experience fluctuations in the water temperature during use, your thermostat could be the culprit. A properly functioning thermostat will consistently maintain the set temperature.

2. Insufficient hot water

If your hot water runs out faster than it should or if it’s not as hot as usual, it might be a sign that your thermostat isn’t working correctly. This could be due to incorrect temperature settings or a broken thermostat.

3. No hot water at all

The most apparent sign of a malfunctioning thermostat is a complete lack of hot water. If you’re only getting cold water from your tap, most likely the thermostat is broken and can’t trigger the heating element.

4. Overheating

On the flip side, if your water is scalding hot and exceeds the temperature setting on your thermostat, it could be a sign that your thermostat is malfunctioning and not properly regulating the heat.

5. Frequent cycling

If your water heater turns on and off frequently, this could be a sign that your thermostat isn’t functioning correctly. This phenomenon, known as “short cycling,” can lead to excessive wear on your water heater and increased energy consumption.

6. High energy bills

If you’ve noticed a spike in your energy bills without a corresponding increase in water usage, your water heater thermostat might be at fault. It may be working inefficiently, causing your heater to use more energy to maintain water temperature.

7. Unusual noises

A faulty thermostat can cause your water heater to make unusual noises such as popping, cracking, or humming. These noises can be caused by overheating due to the thermostat not correctly controlling the temperature.

8. The age of your water heater

Although not a direct sign of a faulty thermostat, the age of your water heater could be an indicator of potential problems. Most water heaters last around 10-15 years. If yours is older, it may have a worn-out thermostat.

9. Failure to respond to adjustments

If your water heater does not respond to temperature adjustments on the thermostat, it could be a sign of a faulty thermostat. A functioning thermostat will trigger the heating element once the temperature is adjusted.

10. Physical damage

Visible damage to your thermostat such as corrosion, char marks, or discoloration is a clear sign of a faulty thermostat. If you observe any physical damage, it is recommended to replace the thermostat immediately.
