Do you recently notice that there’s a blinking snowflake on the thermostat of your house? If so, then it’s likely that your thermostat is entering ‘Delay Mode’, which usually happens if the thermostat system is short-cycling. This condition may damage the device if it’s not resolved as soon as possible.

So what does the snowflake symbol on the thermostat mean? It is a condition that may be prompted by a short-cycling, which is when the cycle system of the thermostat goes faster than it’s supposed to.

The air conditioner or furnace is switching on and off much quicker than it should, which may harm the system because it’s working harder.

Now, the short-cycling condition may be caused by one of several possible reasons, as listed below:

  • The thermostat is not suitable size-wise with your space: If the HVAC professional that you’ve hired used and installed a thermostat device with bigger capacity than your space needs, then the cooling or heating cycle may proceed to quickly for the space. While this may seem harmless, this can cause short-cycling on the system.
  • The thermostat needs repairs: Short-cycling may be caused by anything that causes power outage. Other possible issue that may cause the condition is corroded flame sensor, breaker issue, condensate switch issue, or if there’s an item that accidentally falls into the vent.
  • Outdated maintenance: Some seemingly insignificant issue such as dirty air filters may cause short-cycling condition because it restricts the airflow. You need to examine and perform standard maintenance regularly.
  • Thermostat issues: It is possible that your thermostat device doesn’t function properly or need to be replaced. In case of this, try to place the device under direct sunlight or near an appliance that can generate cold or heat to prompt it turning on and off normally.

Delay mode is an attempt to protect the thermostat system from conditions that may permanently damage it, as listed above. Notice that the device is going under short-cycling conditions. The temperature at your home may not work correctly for a while, so try to take a brief break to see if the issue will resolve – in approximately five minutes. If it won’t, you may need to fix the reason behind the short cycling.

Now that you understand what the White Rodgers thermostat blinking snowflake means, you may take the correct steps to make it function properly again. Do not rush and wait as instructed for the system to start as it should again.

Also, note another flash warning that may indicate another problem on your system. If another issue appears, you may need to contact an HVAC professional soon to see if the system will need repair.
