How To Fix When Wyze Thermostat Not Turning On?

Now when the possibilities are on the table, it’s time to start excluding one by one until the true cause is revealed.

Just keep in mind to follow the order of our solutions for the best results in your troubleshooting attempts.

Here’s how to get your Wyze thermostat working again in easy steps:

Solution #1 Secure Wyze Thermostat Wires

The first thing you should review is the cable situation with your Wyze thermostat.

There are high chances that one or more of the wires got disconnected or were originally plugged into an incorrect terminal, to begin with.

The main wire you want to care about is the RC wire of your thermostat, which connects the unit to the HVAC system.

As for the other wires, it’s enough to verify that they are not damaged anywhere on their body.

Here’s how to secure the wires of your Wyze thermostat:

1. Open the Wyze app.
2. Tap on Mounting.
3. View all of the available terminals that are displayed on the screen.
4. Tap on “Next” and check where the RC wire must be connected.
5. Once identified, take the front panel of your Wyze thermostat off.
6. Grab the red RC wire and connect it to the terminal, displayed on your phone.
7. Close the Wyze thermostat.
8. Test its functionality.

Note: Check for any visual body damage inflicted on the wires.

Solution #2 Take Out The Float Switch

One of the reasons that caused your Wyze thermostat to stop working is inserted float switch.

When that plug is inserted into your setup, your thermostat, ACs, and entire HVAC system will be temporarily suspended from running.

For this solution, you should take out the float switch from the HVAC compartment.

The float switch is situated on the pipe coming out of the HVAC furnace, which is the only single pipe you will notice.

The float switch looks a little like a crank and can also be undone and removed from the pipe. Once the float switch is taken out, test your thermostat.

Note: It may take a little force to undo the float switch, due to its anti-children mechanism.

Solution #3 Clean The AC Drain Line

When most HVAC system AC drain lines get clogged, the entire configuration will temporarily stop functioning.

That is to preserve the current state of the drain line and prevent it from getting any worse.

In that regard, here’s how to clean the AC drain line of your system:

1. Turn your air conditioner off.
2. Locate the access point of the drain line.
3. Pour distilled vinegar into the pipe.
4. Let the solution eat the debris away for 30 minutes.
5. Test your thermostat.

Note: Once the AC drain line is unclogged, you should notice that your system will start working properly again.

Solution #4 Reset Thermostat With Control Wheel

Users report that by holding the button of their Wyze thermostat, they manage to reset the device and unfreeze it.

Yes, your Wyze thermostat could have frozen at a stage where nothing is displayed, deceiving you into thinking that no power is reaching the device.

In that regard, what you should do in this solution is hold the control wheel of the thermostat for 30 seconds.

A prompt should appear on the screen, asking you whether you want to erase all settings or not. On that, tap “Yes” and wait for the reset to go through.

Note: Remember to re-add the thermostat through the Wyze app once the reset is complete.

Solution #5 Reset HVAC Circuit Breaker

If you couldn’t reset the thermostat through its hardware, chances are that no power is reaching your HVAC system at all.

If that’s the case, you can reset the thermostat along with the HVAC compartment through the circuit breaker box in your household.

Here’s how to reset the Wyze thermostat through the circuit breaker:

1. Go next to the circuit breaker box.
2. Open the compartment.
3. Search for the HVAC switch, that should have an independent power valve there.
4. Press the valve and slowly turn it towards its OFF side (also has written ON and OFF).
5. Once disabled, wait for 30 seconds.
6. Spin the breaker back to its ON position and check if the Wyze thermostat is going to boot.

Note: Remember to slowly turn the circuit breaker to lessen the chance of electrical damage to your HVAC system and thermostat.

If these solutions didn’t help solve your Wyze thermostat problem, consider reaching out to professional HVAC assistance to take care of the problem for you!

Thus to fix when the Wyze thermostat won’t start, reconnect each wire to its correct terminal and take out the float switch if it’s plugged. Reset your thermostat using the control wheel and clean the AC drain line. Finally, reboot your entire HVAC system, using the circuit breaker switch.
