Tips to Troubleshoot Your Luxpro Thermostat

1. Restart Your Device

This is the first thing you want to do whenever you have any issue with your Luxpro thermostat. Restarting the device can help fix a variety of issues, and it’s also pretty easy to do. Even if you are a first-time thermostat user, you can restart your thermostat all by yourself.

Here is how to restart a Luxpro thermostat:

  • Switch the system mode to OFF.
  • Remove the thermostat from the wall.
  • Remove the battery cover and remove the batteries (if your thermostat is battery powered).
  • Wait for about 15 minutes before replacing the batteries and the cover.
  • Find the hardware reset button on the side of the thermostat (a round button labeled “H.W. Reset”). Use a pin/paper clip to press down the button for about 5 seconds. This should restart your thermostat and possibly fix the issues you’re having with it.

But if that doesn’t solve the problem, see the next step.

2. Reset the Thermostat (Software Reset)

If restarting the device couldn’t fix the problem, you may have to reset the thermostat. Regardless of the cause, resetting the device may fix wrong settings or any minor glitch in your device.

However, keep in mind that resetting your device will erase all previous settings and then restore factory settings. So you’ll have to go back to the initial setup procedure again—and it’s worth it as long as it’s going to fix the problem with your Thermostat.

Not sure how to reset your Luxpro thermostat? The process is simple! You only need to find the Reset button on your device. It is a small button labeled “R. Reset”. Long-press the button until the screen blinks.

This will reset the thermostat and possibly fix any glitch causing undesirable operation.

3. Check and Replace the Batteries

Low batteries can also cause performance issues (if the thermostat uses batteries). And if the batteries are completely dead, your thermostat won’t work at all.

The unit needs to get enough supply of power when using batteries, else it will affect its functionality. So check your batteries and replace them if they are low or completely drained.

Ensure you get the right batteries and do not mix new batteries with old ones to avoid battery leakage and other issues. Battery-powered Luxpro thermostats use only alkaline batteries—non-rechargeable. Energizer and Duracell are excellent brands to consider.

More so, if the thermostat is plugged into your home electrical system, make sure the electrical outlet works well. Also, check the fuse or circuit breaker if it is tripped off. If that is it, manually flip it back on. This should fix some problems related to performance or so.

4. Check for Any Wiring Issue

Wire issues can also cause your Luxpro thermostat to not function optimally. If one wire inside the unit is not well connected or damaged, the thermostat will not work. So, remove the thermostat from the wall and check for any wiring issue. If any of the wires are loose, put them back in, and also look out for any damaged wire so you can replace it.

If you are not sure how to check this, especially if your thermostat is connected to your home electrical system, call an experienced technician to help you check it.

The technician should be able to detect any other wiring issue that may cause your thermostat to malfunction.

5. Clean the Thermostat

If you have dust accumulated inside your thermostat, it can clog around the wires and mess up the working of the device. So get a soft brush or a dry air container to clean off any dust or particles inside the unit.

Did you fix your Luxpro thermostat after trying one or all of the above steps? If so, congratulations! But if not, you may have to contact Luxpro Technical Support for further help.

And if your Thermostat is too old, you may consider replacing it as its lifespan also determines its effectiveness.

Related Questions

Why does my Luxpro Thermostat say override?

Override is one feature of a Luxpro thermostat. When your thermostat is in Program RUN mode, “OVERRIDE” appears in the temperature area of the display.

During this time, you can easily change your set temperature by pressing the UP and DOWN buttons. And when it reaches the start of the next period, the set temperature will revert to the programmed value saved in memory.

To cancel OVERRIDE in your Luxpro thermostat, move the switch to the OFF position and return it to the COOL or HEAT position

Where is the reset button on Luxpro Thermostat?

Reset button location may differ based on the model, as Luxpro thermostats are of different models. However, for most Luxpro thermostats, you can find the reset button on the right and left side—labeled “H.W. Reset” and “R. Reset”.

Note: “H.W. Reset” is for hardware reset, while “R. Reset” is for software reset. So basically, there are two reset buttons on your Luxpro thermostat.

How do I reset a Luxpro Thermostat?

Here is how to reset a Luxpro thermostat:

  1. Locate the reset button on your device (it is small and has “H.W. Reset” or “R. Reset” written on it).
  2. Press and hold the button for a few seconds (about 5 seconds)
  3. The screen will blink, then the thermostat will automatically reset itself.

Note: You can either perform a hardware or software reset. The H.W Reset button is for hardware reset, while the R. Reset button is for software reset. If you’re looking to reset your device to fix issues, a software reset is recommended.

Why is my Luxpro Thermostat not cooling?

If your Luxpro thermostat isn’t turning on your cooling system, here are some reasons this might be happening:

  • The thermostat is not set to the COOL.
  • The thermostat is reading the wrong temperature.
  • Incorrect settings/glitches.

To fix this issue, first ensure that your thermostat is set to the COOL position. Then if the problem persists, reset the thermostat to fix incorrect temperature settings and glitches (see how to reset a Luxpro thermostat above).

More so, if your thermostat runs on battery power, replace the batteries for continuous, reliable operation.

Why is my Luxpro Thermostat display not working?

If your Luxpro thermostat display is not working; as in the screen is blank, here are the possible causes:

  • Low battery power.
  • Tripped circuit breaker.
  • Faulty wiring/blown fuses.

The first step to fixing this issue is to reboot the thermostat. If that doesn’t work, replace the batteries (if your thermostat is battery-powered).

If none of the above works, perform a software reset on the thermostat. Next, check the circuit breaker of your HVAC system to see if it has tripped. If so, flip it to the ON position.

If you have the expertise, you can proceed to check your thermostat wiring and fuses to see if there’s any fault. If you’re not sure how to do that, get an HVAC expert to check and fix wiring issues.

Your Luxpro thermostat display should work fine after trying all the fixes.

Final Note

As you may have read above, there’s no specific cause of this problem — “Luxpro thermostat not working”. Wiring issues, dead batteries, or dust accumulated in the unit can cause your thermostat to develop this problem.

But the good news is you can fix the issue by restarting and/or resetting your device. You may also consider replacing the batteries, removing dust, and check that there’s no wiring issue.

Your Luxpro thermostat should be up and running properly again after applying all the tips correctly. If not, contact an HVAC system expert or Luxpro Technical Support for help.
