Problem 1: Wyze thermostat suddenly not turning on anymore

Usually, the reason why your Wyze thermostat is suddenly not turning on anymore is either an HVAC wiring issue or a blocked drainage pipe in the air conditioner.

HVAC System’s wiring

Loose wire connections can cause the thermostat to disconnect from the HVAC system. If there is no connection, the thermostat cannot turn on. By following the next steps you can determine whether the wiring is causing the thermostat not to turn on.

Check the wires at the thermostat

  • Turn off the HVAC/thermostat circuit breaker/s. Usually, it is only one circuit breaker servicing all the HVAC devices, but in some houses, you’ll find that more than one circuit breaker is used to service all the HVAC devices. Ensure that you switch off all the relevant breakers.
  • Take your Wyze thermostat from the wall and inspect the wiring at the back of the device. Look for any loose wires. If you detect loose wires, reconnect them to the thermostat terminals. Also, ensure that all the other connections are still secure. To test whether they are secure, you can lightly pull on the wire.
  • Place the thermostat back onto the wall and turn the circuit breaker/s on again. Remember, to put a circuit breaker on, you first have to move the switch completely to the “Off” position and then pressed it to the “On” position until it clicks into position. If the Wyze thermostat now turns on, you’ve fixed the problem.

Check the wires at the HVAC control panel

  • If the thermostat is still not turning on, you have to check the wiring at the HVAC control board.
  • Turn off all the relevant circuit breakers again and locate the control board on your HVAC system.
  • Ensure that all the wires are still securely connected to the board. If you find disconnected wires, re-attach them to the board.
  • Turn the circuit breakers on. If the Wyze thermostat now turns on, you’ve successfully fixed the problem.

Conduct a system test from your app

If your Wyze thermostat is still not turning on conduct a system test on your Wyze thermostat. How to do this:

  • Open the Wyse app on your mobile phone and tap the Wyze thermostat option.
  • Then click on the “Settings” icon to go to the “Setting” page.
  • Select “Advanced,” and then select “System Test.”

After the Wyze thermostat has completed the test, your thermostat should turn on. If the thermostat is still not turning on, you have to keep on troubleshooting.

Unclog the AC’s drainage pipe

If all the wiring is in place and securely connected and the Wyze thermostat is still not turning on, it might be a clogged AC drainage pipe that is causing the problem. The float switch inside the air conditioner turns off the system if the drain pipe is full. This is a built-in safety feature to prevent water from flooding your house.

Therefore, your next troubleshooting step is to check whether your air conditioner’s drainage pipe is dirty or clogged.

  • Locate the drain pipe outside your house.
  • Detach the float switch from the drain pipe and empty the pipe.
  • Sometimes you will need a vacuum or plumber’s snake to remove the clogging.
  • When the pipe is clean, attach the float again. Your Wyze thermostat should now turn on.

Contact an HVAC technician

If neither the corrected wiring nor a clean drain pipe enables your Wyze thermostat to turn on, it is recommended that you contact an HVAC expert. An HVAC technician will have the tools and know-how to find and fix the problem.    

Problem 2: Your Wyze Thermostat does not turn off.

This problem is quite the opposite of the previous problem. The previous problem was that the thermostat doesn’t turn on, but it might also happen that your thermostat doesn’t turn off when your home has reached the set temperature.

Power cycle

To troubleshoot, your first step is to power cycle your Wyze thermostat.

  • Turn off the circuit breaker that powers the HVAC system for about 30 seconds. Usually, it is only one circuit breaker servicing all the HVAC devices, but in some houses, you’ll find that more than one circuit breaker is used to service all the HVAC devices. Ensure that you switch off all the relevant breakers.
  • Ensure that your wiring is secured and connected.
  • Turn the breaker/s back on. Remember, to put a circuit breaker on, you first have to move the switch completely to the “Off” position and then pressed it to the “On” position until it clicks into position. If the Wyze thermostat now turns on, you’ve fixed the problem.

Factory reset

If the thermostat is still not turning off when the set temperature has been reached you have to perform a factory reset. To do a factory reset, you have to hold the control wheel for 10 seconds after you’ve pressed it.

All your previous settings and programming will now be erased and you have to set up the Wyze thermostat as if new. If you don’t have your owner’s Setup Guide anymore, check online for guidelines on how to set up your model Wyze thermostat.

Contact the HVAC technician

If the thermostat still keeps on running after you’ve taken all the steps described above, you’ll have to call an HVAC technician.

Problem 3: The Wyze thermostat is not displaying the correct temperature

When a thermostat is not displaying the correct temperature, the result is that it is warmer or cooler in your home than the temperature displayed on the thermostat.

To troubleshoot, you have to follow the following steps:  

Power cycle

To try and fix the problem, your first step is to power cycle your Wyze thermostat.

  • Turn off the circuit breaker that powers the HVAC system for about 30 seconds. Usually, it is only one circuit breaker servicing all the HVAC devices, but in some houses, you’ll find that more than one circuit breaker is used to service all the HVAC devices. Ensure that you switch off all the relevant breakers.
  • Ensure that your wiring is secured and connected.
  • Turn the breaker/s back on. Remember, to put a circuit breaker on, you first have to move the switch completely to the “Off” position and then pressed it to the “On” position until it clicks into position. If the Wyze thermostat now turns on, you’ve fixed the problem.
  • Set your thermostat to the desired temperature and wait for about 24 hours to verify whether the Wyze thermostat is now always displaying the correct temperature. If so, you’ve resolved the issue.

 Factory reset

If the thermostat is still displaying the incorrect temperature the next step is to perform a factory reset. To do a factory reset, you have to hold the control wheel for 10 seconds after you’ve pressed it.

All your previous settings and programming will now be erased and you have to set up the Wyze thermostat as if new. If you don’t have your owner’s Setup Guide anymore, check online for guidelines on how to set up your model Wyze thermostat.

Contact the HVAC technician

If the thermostat still keeps on displaying the incorrect temperature you’ll have to call an HVAC technician. The technician will be able to uninstall your Wyze thermostat and re-do the wiring if all other troubleshooting efforts have failed.

Problem 4: The air being blown into your home is the opposite of what you’ve selected

The issue here is that although you have turned on the heat, cool air is blowing out, and vice versa.

If your system is equipped with a heat pump

To troubleshoot this problem if you have a heat pump system, you have to navigate to the Wyze thermostat settings and enable “Swap Heat and Cool.”

If your system doesn’t have a heat pump – check the firmware

If the previous step has not fixed the problem, or you don’t have a heat pump system, you have to ensure that your Wyze thermostat’s firmware is up to date. To find out whether your Wyze thermostat has received the latest updates, go to the “Account” tab and select “Firmware Update.”

If your thermostat gives you the message that an update is needed, do the update immediately.  

Factory reset

When your thermostat has been updated and the issue still persists, the next step will be to perform a factory reset by pressing and holding the control wheel for 10 seconds. Then you have to set up the thermostat like new.

Remember, all your previous settings and programming will now be erased and you have to set up the Wyze thermostat as if new. If you don’t have your owner’s Setup Guide anymore, check online for guidelines on how to set up your model Wyze thermostat.

Uninstall and reinstall the wiring

If the issue is still not resolved, use your Wyze app and uninstall your thermostat wiring. Then wait 30 seconds and reinstall the wiring.

Call an HVAC expert

If none of these actions has resolved the problem, you’ll have to contact your HVAC technician.

Problem 5: Your Wyze thermostat doesn’t connect to your Wi-Fi network or you get the message “Connection failed”

When your Wyze thermostat cannot connect to the Wi-Fi network, you will receive the message “Connection failed.”

Update the app 

Your first troubleshooting step is to ensure that your app is up to date. To do that, navigate to the “Account” tab and tap on “About.” The current app version will be listed under the Wyze logo. Compare the version on your app with the newest available version in your app store. Update the app and then try to connect to the network again.

Remember, Wyze devices are not compatible with 5 GHz Wi0Fi networks. Thus ensure that your phone or tablet is connected to a 2.4 GHz Wi-Fi network.

Power cycle

If you still get the same message, force closes your app and power cycle the thermostat. By turning off the circuit breaker that powers the HVAC system for about 30 seconds. If the thermostat is now connecting to the Wi-Fi network you’ve solved the problem

Reboot the router and do a factory reset on your Wyze thermostat

If your Wyze thermostat still doesn’t connect to the network, reboot your router and do a factory reset by pressing and holding the control wheel for 10 seconds. Turn your phone off and turn it back on. 

Remember, all your previous settings and programming will now be erased and you have to set up the Wyze thermostat as if new. If you don’t have your owner’s Setup Guide anymore, check online for guidelines on how to set up your model Wyze thermostat.

If the problem persists, you can also try to move the router closer to the thermostat.
