Why Is My Honeywell Thermostat On Cool But Not Working

Honeywell thermostat battery replacement if thermostat doesn’t work AC won’t turn on

Honeywell thermostats are some of the best thermostat systems on the market. They are world-renowned for quality and their effectiveness, but they are not immune from problems. A commonly experienced problem is the thermostat not cooling the house or room, even if the thermostat is on cool.

The most common reasons for a thermostat not cooling include:

  • Problems with airflow.
  • Problems with the furnace or heating system.
  • An issue with the thermostat device.

Of these problems, a blank control panel screen is experienced the most by Honeywell users. This problem is usually not difficult to fix.

A blank thermostat device screen is usually due to dead batteries, or the system has encountered a minor fault and requires a reset.

If your thermostat screen is blank, the first step is to check the batteries in the device. Replace the batteries, reinstall the thermostat faceplate, and check if it is now working.

If not, locate the circuit breaker switch for the thermostat system and turn it off for a few seconds. Restore power to the system, and check if it is working. If this does not solve the issue, it may be time to contact a technician to assess and assist with repairs.

S To Find The Model Number On The Back Of The Model

  • The first and foremost thing that you should keep in mind is to remove it from the electric socket. Keeping it connected to a source of electricity increases the chances of you being exposed to live wire which can give you a fatal shock.
  • The second step is to slide over the device off the base cover. Once it has been separated, you will find the model number written on the back of the device.
  • Once you are done noting the number, slide it back into the base cover and put it back in its original place. Your work here is done.
  • In case you cannot find the model number of your thermostat in any of these three places then there is only one option left. Check out the box or the user-manual that came with it for the model number. You will surely find it there.

    How To Reset The Thermostat

    After changing the battery of your honeywell thermostat, you may consider resetting the whole system.

    While this is not always necessary, there are various situations and scenarios that may motivate you to do the reset. They include

    -Inaccurate regulation by the thermostat.: If the thermostat is not able to regulate the temperature correctly, you may want to reset it so that it can regulate it correctly.

    -Inaccurate temperature display on the thermostat: If the thermostats display is not accurate, you may want to reset it so that it displays an accurate temperature.

    -Corrupted data and time: If your date and time on your thermostat are incorrect, you may want to reset it so that you can have the correct date and time on your thermostat.

    -Improper function of some of its functions: If some of your Honeywell thermostats functions are malfunctioning, you may want to reset them so that they will work properly again.

    How Do I Know If My Thermostat Needs A New Battery

    All Honeywell thermostats that use batteries will have an indicator on the control panel. If the system has a screen, a warning such as Low Batt indicates that you must replace the batteries soon. Some models do not have an indicator but will instead flash the snowflake icon.

    If the Honeywell thermostat system that you have installed has a screen or a control panel, it will most likely require batteries to power that control panel. Every thermostat model like this must have some form of indication for when the batteries are running low.

    Fortunately, Honeywell thermostat systems only require a battery change of about once a year. The extended battery life indicates that these systems do not use batteries very quickly. Even when the low battery indicator does come on the screen, you will still have about two months before the control panel stops functioning.

    Some Honeywell systems have a final warning feature if the batteries become too low on power. If the batteries get too low, the screen will not turn on until fresh batteries are installed. This is the final indication of low batteries.

    Some non-programmable thermostats made by Honeywell are so simple that they do not require batteries to function. The control units are do not require a power source, as they are essentially just a switch, and if they do need power, they can be wired into the thermostat power source because they require such little power.

    Thermostats such as the Honeywell T87N1000 Tradeline Thermostat do not require batteries. This system has a control unit without a screen or even any buttons. It is simply a dial that sets the temperature of the thermostat.

    This system and others like it do not require batteries whatsoever. The downside is that these systems are straightforward and do not have many features. Systems like this have limited capabilities and can not be programmed other than raising or lowing the temperature.

    Honeywell manufactures a range of these non-programmable systems. A significant advantage to using these systems is that they are straightforward to use there is not much to go wrong with them they are reliable, easy to install, and far less expensive than more sophisticated thermostat systems.

    How Do I Get My Honeywell Thermostat To Work After Changing The Battery

    Replace Batteries On A Honeywell Thermostat / Heat, AC Or Back Light Not Working?

    Suppose the thermostat is not working after replacing the batteries. In that case, the batteries are in the wrong orientation, the faceplate may be incorrectly seated, the batteries may be faulty, or the system may require a reset.

    The first thing to check if the thermostat system is not turning on after a battery change is if the control panel faceplate or the battery compartment lid or tray has been reinstalled correctly. If the pins in the control panel are not making proper contact with the baseplate, the control panel will not turn on.

    Check the control panel to make sure that it is seated securely. If not, carefully remove the panel as not to damage any connections, and replace it securely onto the base plate.

    If this does not solve the problem, follow the steps to access the thermostat battery compartment. Inspect the batteries to ensure they are installed in the correct orientation according to the diagram on the thermostat.

    If the batteries are not installed with the correct polarity orientation, the thermostat will not function. If the batteries are installed incorrectly, rectifying this should solve the problem.

    If the problem persists, place the batteries into another device to check that they are discharging properly.

    If all is well with the batteries and the control panel, the system may need to reset. Since the control panel is not working, you must reset the system by turning off the electrical supply at the circuit breaker.
