The Trane thermostat is reliable and can be programmed to work exactly how you want. There are times when it displays a “waiting” message. When this happens, you cannot use the thermostat. So, why does the Trane thermostat say wait?

The “Wait” message displayed by your Trane thermostat means your device is waiting to turn on the compressor of your HVAC system. This is necessary to prevent damage to the compressor system. The warning should not last more than 5 minutes if your system is working correctly.

Ideally, the thermostat cannot be used when it is in the “waiting” mode. It is a sign the compressor of your HVAC system is not ready. Maybe it is protecting the compressor or it is a sign of an underlying problem, read more to find out why does Trane thermostat say wait.

Reasons Why Trane Thermostat Says Wait?

There are a few reasons why the Trane thermostat says to wait. These are the common ones:

Safety Feature

When your thermostat displays a “wait” message, it is a sign that the compressor is not ready. Thus, it is a safety precaution to protect your system. However, if your HVAC system is fine, this message will disappear in less than 5 minutes. If the message persists, it is a sign of other serious problems.

Ideally, the HVAC system needs time to adjust after you power it on. If the compressor is activated early, it can get damaged. This is known as short cycling. When it takes a few minutes for the compressor to adjust, you can prevent short cycling.

Improper Voltage

If the “wait” message persists for more than 5 minutes, then it might be a sign your thermostat is not getting the required voltage. In this case, troubleshooting is needed to find out the problem. You can use a voltmeter to check whether the voltage applied is within the recommended range. Also, you should ensure there are no faulty or shorted wires.

Electrical Problems

There are times when wires can be exposed or slip out of place. Trane thermostats with faulty wires can display a “Waiting” message. Other thermostats with similar problems can display “Heat On” or “Cool On.” They all imply the same thing as they want to protect the compressor in your HVAC system.

When this message pops up, it can be a sign of an underlying electrical problem. In such a case, you should contact a professional to help you.

AC Problem

Sometimes the “Wait” message can be a sign of a worst-case scenario, such as the heater or AC going out. When there is an issue with the furnace or compressor, the “wait” message will show up. Although this is not good news for you, it is something that can happen.

How To Fix Trane Thermostat Wait Message?

There are different ways you can use to fix the Trane thermostat that displays the “Wait” message. The method you choose should be based on the cause of the warning. Sometimes you may need to try different methods. These are the common methods:

Wait for the problem to resolve itself

To fix your Trane thermostat wait message, you might have to wait up to 10 minutes. Remember Trane thermostats take 5 minutes or less to get the compressor ready to prevent short cycling. Just relax and enjoy your cup of coffee. After a few minutes, your HVAC system will start working fine.

Replace the Batteries

After waiting for 10 minutes and your Trane thermostat keeps displaying a wait message, it might be a sign of weak batteries. That is because if the thermostat does not have adequate power, you might find it challenging to activate the HVAC system.

Since your HVAC system will not start, the wait message will not disappear. Look for the low battery indicator on your Trane thermostat. Remove the old batteries and install new ones.

Reset the Breakers

Sometimes resetting the HVAC system from the circuit breaker can solve this problem. Try this method if the system does not work even after changing the batteries. Make sure you turn off your thermostat and HVAC system.

Look for the controls of your HVAC equipment and then power them off. Switch them on after 20 to 30 seconds. You should note that problems with your system’s circuits and connections can stop your HVAC system from working. This might result in the thermostat’s waiting signal.

Check the Voltage

There are times when you need to reset your HVAC circuits and wait for the previous trick to solve the problem. However, if it does not, then it is a sign this is a short circuit problem. Thus, you should check the voltage. You will need a voltmeter or multimeter. Make sure you only try this if you are good at electronics. If not, leave it to professionals.

Reset the Thermostat

If all the above troubleshooting ideas fail, the is something wrong with your thermostat. You should consider restarting it. By restarting it, you can reset processes that are lagging the thermostat. In this case, you need to detach it from the equipment and reattach it after a few minutes. Always consult the user manual when restarting your thermostat.


Waiting for the HVAC system to start working can be quite frustrating. Nevertheless, the Trane thermostat wait feature is useful in protecting your equipment from undue damage. Although it is somehow an inconvenience, it ensures the HVAC system is safe against short cycling and other problems. If your Trane thermostat displays the wait warning, you should follow the above steps to resolve the error. After this, you can continue enjoying the remote access and energy-efficiency features of a Trane thermostat.
