Are you feeling the heat, but your Honeywell thermostat is not cooling your home? Don’t sweat it – troubleshooting the problem could be simpler than you think.
In this guide, we’ll walk you through step-by-step instructions to help you troubleshoot and resolve the issue with your Honeywell thermostat not cooling.
To troubleshoot a Braeburn thermostat that’s not cooling;
- Check if it’s set to cool mode and if the system is in delay.
- Verify that the furnace power switch or circuit breakers are not off or tripped.
- Inspect the thermostat wiring for loose wires or broken connections
- Ensure that the thermostat is configured for the correct system type.
- If none of these steps work, your system is probably low on freon
- Still not cooling? Replace your thermostat.
# Before you go into any of the troubleshooting tips, make sure you have no Saver switch from your utility company. Otherwise it could be the reason your thermostat is not cooling.
Possible reasons a Braeburn thermostat is not cooling
|Thermostat not set to cool mode||Check if the thermostat is switched to cool mode|
|System in delay||Wait for the delay to finish|
|Furnace power switch off||Verify the furnace power switch is turned on|
|Circuit breaker tripped||Check circuit breakers and reset them|
|Thermostat wiring issues||Inspect wiring and connections|
|Incorrect system configuration||Ensure the thermostat is configured for your system type|
|Freon/Refrigerant leaked out||Call pro for recharge|
|Faulty thermostat||Replace the thermostat|
Check if the thermostat is switched to cool mode
Ensure that the thermostat is set to cool mode and not heating or off mode. It may seem obvious, but sometimes people overlook this simple step.
If your Braeburn thermostat is not set to cool, it will not activate the air conditioner even if you set the temperature at the lowest setting.
So make sure to switch it to cool mode.
Verify the system is not in delay
If the thermostat is set to cool, but the system is not turning on, check if there is a delay. Some systems have built-in delays to prevent short cycling.
Typically, when any HVAC system is undergoing system time off delay, there will be a snowflake icon blinking on the thermostat display. Sometimes it will just be the word ‘cool’ or the phrase ‘cool on blinking’
When you see those symbols blinking don’t be alarmed
Wait a few minutes to see if the thermostat starts cooling after the delay is over.
Verify the furnace power switch is turned on
Check if the furnace power switch is turned on. A furnace switch looks more light than a light switch and is located near the furnace.
The switch may have been mistakenly left off by previous maintenance works.
Turn the switch on if it is off.
Note that sometimes, it’s the furnace door that may have been left open. These days HVAC systems are equipped with safety door switches that cut power to your system when they open or not properly closed
So make sure your furnace door is properly closed.
Check circuit breakers
Go to the electrical circuit breaker box and verify that there are no circuit breakers tripped. The circuit breakers for your HVAC system are usually two, one for the outdoor unit and the other one for the air handler( furnace).
Make sure none of them is tripped. If a breaker is tripped, reset it and wait for a few minutes to see if the system turns on.
Inspect thermostat wiring
To inspect the wiring of the thermostat, remove the upper cover of your thermostat.( this can depend on your model).
Look at the wiring and ensure that the previous wiring matches the new one. Check that there are no loose connections.
Where you don’t have separate wires for the Rc and Rh wire, put a jumper in between.
Verify the thermostat is configured to your system type
If this is a new thermostat installation, you must ensure that the thermostat is configured to the type of system you have, such as a heat pump or air conditioner.
If the configuration is incorrect, it may cause the system to cool when it’s expected to heat or vice versa and many times, the system will not work at all.
Different systems have different configurations.
For example, configuring a 2-stage heating and 2-stage cooling will be different from the way you will configure a single stage or single stage heating. So make sure everything with the configuration is right.
Low/Leaked Out Freon
If you have checked with the five steps above and your thermostat is still not cooling there is a high chance that refrigerant (freon) has leaked out of your system and there is little or nothing left.
And If you believe that freon has leaked out of your system, I strongly advise that you call a local licensed technician to troubleshoot the problem considering that there may be laws restricting who can and can not work with refrigerants.
When you call a technician, he/she will pinpoint the source of the leaks and seal them off before recharging the system with more freon.
Replace the thermostat
If none of the above steps help, the thermostat may need to be replaced. A faulty thermostat can cause the system not to cool. Especially if your thermostat is 8 years old or more. It may have just saved its purpose in your home and could be the right time to have it replaced.
Why is my Braeburn thermostat not cooling even though the fan is running?
If your Braeburn thermostat is not cooling even though the fan is running, it could be due to an issue with the compressor or refrigerant levels
How often should I replace my Braeburn thermostat?
Braeburn thermostats are designed to last for many years. However, if your thermostat is over or over 8 years old and is not working correctly, you should consider replacing it.
Can a faulty Braeburn thermostat cause high energy bills?
Yes, a faulty Braeburn thermostat can cause high energy bills as it can prevent the HVAC system from running efficiently. Replacing a faulty thermostat can help you save money on your energy bills.
In conclusion, a Braeburn thermostat not cooling can be a frustrating issue to deal with, but fortunately, there are several steps you can take to troubleshoot and resolve the problem.
That said, we hope that after following the steps outlined in this guide you have got your thermostat back to working.
Remember to perform regular maintenance on your HVAC system and thermostat to prevent future issues from occurring.
