Recently a friend of mine called me to have a look at their Luxpro Thermostat thinking that because I had a fancy Smart Home Thermostat I would be able to fix this one. This lead me to learn quite a bit about the Luxpro Thermostat and how to fix common issues after traipsing forums, Reddit posts and trying things out for myself. As such, this is my conclusive guide on how to fix the Luxpro Thermostat.

Why is my Luxpro Thermostat not working?

Unfortunately, there’s a particularly wide range of potential issues that can arise with varying models of the Luxpro Thermostat, however, some of the most common ones are the following:

  • Luxpro Thermostat Frozen (How to Reset)
  • Forgotten Keypad Lock Code
  • Blank Thermostat Screen

How to reset a Luxpro Thermostat

There are two methods of resetting a Luxpro Thermostat, one of these will wipe any custom program settings (Software Reset) and the other will keep all your settings (Hardware Reset). We recommend trying to do the Hardware Reset first, this will allow you to keep all your settings.

Hardware Reset Luxpro Thermostat (Recommended)

  1. Take off the front panel of the LuxPro Thermostat, be careful not to touch any wires. On the right hand side, you will see a white round button with a label “H.W Reset”.
  2. Hold the “H.W Reset” button for 5 seconds
  3. The screen will go off and come back on within 30 seconds

Software Reset Luxpro Thermostat

This method will erase all prior settings and set the device back to factory defaults, so if you have custom programs or plans keep a note of these.

  1. On the left hand side of the Thermostat you should see a white round button labelled “S. Reset”
  2. Hold the “S. Reset” button for 5 seconds
  3. The screen will temporarily shut off and come back on within 30 seconds
  4. The Date & Time should be correct, but this varies with model to model.

Forgotten Lock Code

If you haven’t set your own code for your Luxpro Thermostat it should be “0000” by default. However, if you have a custom lock code set, you will need to perform a Hardware Reset using the steps above which will bring the keypad code back to the default “0000”.

Your Keypad may still show as locked with a padlock icon but the default should work fine.

Blank Thermostat Screen

This one is a little more complex, if you’ve tried doing a hardware reset and there’s still no display, you will need to take the front panel off to expose the wires, You should turn off the power to your Thermostat via your fuse box first. Make sure the C / G wire is connected properly otherwise the display won’t come on, whilst your power is off, try removing all cables and re-putting them back in to make sure the contacts are correct.

If you’re not familiar with this, it’s highly recommended to contact an Electrician.
