Honeywell Thermostat Snowflake Blinking [Solved]

Are you facing the frustration of a blinking snowflake on your Honeywell thermostat? Don’t worry, we’ve got you covered! In this blog article, we’ll walk you through the common causes behind this issue and provide step-by-step solutions to help you troubleshoot and resolve it.

A blinking snowflake on a Honeywell thermostat is mostly caused by activated delay mode or an activated saver switch (if you are subscribed to one). This issue can be fixed by simply waiting for the delay time to elapse which is typically about 5 minutes or switching the saver switch off, respectively.

Activated Delay Mode

When the snowflake symbol blinks on a Honeywell thermostat, it most probably  indicates that the thermostat is in “Delay Mode.” Delay mode is a feature that prevents the AC compressor from turning on immediately after being turned off.

It introduces a delay to protect the compressor from damage due to frequent cycling.

 To fix this, simply wait for the delay time to end. The duration of the delay mode varies depending on the specific thermostat model but is usually between five and ten minutes.

But if your thermostat continues to blink the snowflake of ‘cool on’, there could be something else wrong with your  HVAC  system.  Let’s look at some of these possible issues in the next section.

What does it mean when your Honeywell continuously blinks Snowflake

Activated Saver Switch

Another reason you may have a blinking snowflake symbol on your Honeywell thermostat is that you have  the  “Saver Switch” activated. 

If you’re signed up for a Saver’s Switch through your utility company or a Demand Response program, your Air Conditioning compressor may be cycling off for longer intervals. This occurs during peak demand hours.

You might want to bypass the saver switch, in that case, here is a video on how to check if the saver switch is closed and how you can by-pass it.

Voltage Problem

A blinking snowflake on a Honeywell thermostat may also indicate a voltage problem. Insufficient voltage can disrupt the functioning of the thermostat, leading to intermittent blinking or other issues. 

By using a multimeter, measure the AC voltage between your Rc wire (or R wire if no RC wire is present) and your Y wire. Your thermostat operates between 20-30VAC,

 If it is out of range there could be  an issue with the power source or wiring, consult a local  HVAC technician to troubleshoot  the voltage problem.

Thermostat Wiring

Incorrect or faulty wiring can cause the snowflake symbol to blink on a Honeywell thermostat. Check if the thermostat wires are properly connected to their corresponding terminals on both the thermostat and the HVAC system. Specifically, ensure that the Rc terminal is connected with a wire.

If there is no wire connected to the Rc wire but connected to the R terminal, put a jumper between the two Terminals. The Rc wire/ terminal is one that is responsible for controlling cooling.

Bad Thermostat

If all the above possibilities have been ruled out and the snowflake symbol continues to blink, it could indicate a faulty thermostat. Malfunctioning internal components or a defective thermostat may cause the blinking snowflake. 

In such cases, replacing the thermostat might be necessary. However before you consider replacing your thermostat, you might want to get a second opinion from honeywell customer support.
