Why Is My Shower Thermostat Not Working?
Taking a cold shower when you’re expecting a warm and relaxing one is frustrating and uncomfortable. A shower thermostat regulates the water temperature and ensures you can enjoy your showers fully.
The problem is when it stops working. Shower thermostats can fail for several reasons, and we’ll discuss some of the most common ones first.
Blocked filter
The first thing to check if your shower thermostat is not working is the filter. A blocked filter can prevent water from reaching the thermostat and thus prevent it from regulating the water temperature.
You can easily remove mineral buildup by unscrewing the filter and washing it under running water.
Faulty thermostat cartridge
A malfunctioning thermostat cartridge can also be the reason behind your shower thermostat not working correctly. Shower water might be lukewarm or cold if the thermostat cartridge doesn’t work correctly. Replacing your thermostat cartridge will fix the problem if it is faulty.
Airlocks
Airlocks in the water system can also lead to problems with your shower thermostat. You may experience lukewarm or cold water with an airlock in your pipes. To fix a faulty thermostat cartridge, you need to replace it.

Electrical issues
Another possible reason your shower thermostat is not working could be an electrical issue. Check the wiring connections to ensure that they’re secure and not loose.
Loose wires can cause short circuits, preventing the thermostat from functioning correctly. If you need more clarification about handling electrical issues, it’s best to seek a professional’s help.
Old or worn-out shower valve
Over time the shower valve can become worn out, leading to problems with the thermostat. When the valve doesn’t work correctly, it can also affect the water’s temperature. Fixing a worn-out valve might require replacing the entire valve, and it’s best to seek professional help.

Step 1: Turn off the Water Supply
Before starting any repairs, it’s essential to turn off the water supply to your shower spa to avoid accidents. Locate the water shutoff valve close to the shower’s plumbing system.
Then, turn the handle so it’s perpendicular to the pipe. This step ensures no water runs through the pipes as you work on your shower spa.
Step 2: Take the Temperature Controller Apart
Take apart the temperature controller by removing the screws holding it. Set aside all screws by unscrewing them with a screwdriver.
Carefully remove the plastic casing to expose the temperature controller, thermostat, and other electrical components. Remember to keep track of all the parts and screws.
Step 3: Inspect the Temperature Controller
Carefully inspect the temperature controller, looking for any visible signs of damage, such as burnt wires, corroded parts, or loose connections. You’ll need to replace the faulty parts if you notice any damage.
If there’s no visible damage, use a multimeter to test the temperature controller’s voltage and resistance. The multimeter will help identify which parts are faulty.
Step 4: Replace the Faulty Parts
Once you’ve identified the faulty parts, you need to replace them. You can quickly get replacement parts from your local hardware store or online. Before installing the new parts, remove any corroded or damaged components and unscrew any wire connections.
Then, install the new parts by following the manufacturer’s instructions. After installing the parts, reconnect any wires that you had previously disconnected.
Step 5: Reassemble the Temperature Controller
Once you’ve finished installing the new parts, it’s time to reassemble the temperature controller. Carefully assemble the plastic casing and screw everything back in place.
Make sure you securely fasten all the screws and parts. Finally, turn the water supply back on and test the temperature controller to ensure it works correctly.
