If your White Rodgers thermostat is blinking a flame icon, it’s likely that your auxiliary or emergency heat is activated and providing secondary heating. AUX and Emergency heat usually kick in when your primary heating source  is  unable to heat adequately.

Flame icon blinking

A flame icon blinking means your secondary stage heating is energized and is heating.

However this blinking symbol  should not be confused with  one that comes up on other thermostat such as Nest and Honeywell. 

On a nest or  honeywell thermostat a flashing flame  icon means that delay mode is active.

Auxiliary or emergency heat will turn on automatically on systems with heat pumps when the outdoor temperatures fall too low for the heat pump to adequately cool your cool.

Emergency heat should not run too long  as it consumes energy way too much.

Solid flame icon

A solid flame icon means that your system has been set to heat mode and  heating is in progress. If you can’t feel heat blowing out of vents, try raising the temperature setting above ambient.

Solid Snowflake icon

A solid snow flame icon on a white rodgers thermostat means the system is set to cooland is cooling

Both snowflake and flame icon flashing

 This  means compressor time delay is active. This should typically last for about 5 mines

What is Compressor Time Delay 

Time delay is a very useful feature on HVAC systems as it protects the compressor from damage. System time delay protects the equipment  from short cycling. 

When there is power outage or when the system is turned off and on quickly, the compressor wont turn on until at least 5 minutes.

Some newer compressors already have a time delay built in and do not require this feature.

On a white Rodgers thermostat, compressor time delay is indicated by a  flashing the Snowflake and Flame Icons for about five minutes

Why does the flame icon keep flashing on  white Rodgers thermostat?

When you experience a flame icon that keeps flashing on your white Rodgers, that could be because it’s too cold outdoors. Heat pumps are designed to heat  your home by  transferring heat from outside to inside. 

They are mostly efficient when outdoor temperatures are  above 35 F. That means when temperatures drop below that, aux heat will kick in to assist the heat pump in cooling your home.
