Emerson Thermostat Blinking Flame Icon

If you’re feeling perplexed by the blinking flame icon on your Emerson thermostat, don’t worry – you’re not alone! In this guide, we explore the possible causes and fixes behind a flashing flame symbol.

The blinking flame symbol icon on an Emerson thermostat primarily indicates that auxiliary heat is operating. Other potential causes for this issue include the activation of the compressor lockout feature or having the thermostat set to Auto mode for both cooling and heating.

It’s worth noting that on Honeywell or other thermostat models, a blinking flame may mean that the delay mode is active. Different thermostat brands and models may use similar symbols to convey various features or statuses, so consulting the specific user manual is key for accurate interpretation. 🔍🔧

Emerson thermostat flame icon meanings


Understanding the meaning behind the flame icon on your Emerson thermostat is crucial for effective operation. Here’s a breakdown of the different flame icon displays:

Flame icon blinking (Aux or Emergency Heat is Operating)

The blinking flame icon on your Emerson thermostat typically indicates that the auxiliary or emergency heating system is currently in use. This occurs when the primary heating system is unable to meet the desired temperature, prompting the thermostat to activate the backup heating system to compensate. This behavior is normal, especially during colder weather conditions or when there’s an issue with the primary heating system. Understanding this indicator helps you recognize when the backup heating system is in operation to maintain a comfortable temperature in your space. 🔍🔥

Both snowflake and flame icon flashing (Compressor Lockout)

The compressor lockout feature on your thermostat serves to prevent the air conditioner’s compressor from starting immediately after turning off. This intentional delay is implemented to safeguard the compressor and extend its lifespan. If the thermostat detects the need for a compressor lockout for a specific duration, it may flash both the snowflake and flame symbols, signaling a temporary disablement of the cooling mode.

You have the option to manually set the compressor lockout to either on or off. Enabling compressor lockout to on means the thermostat will wait 5 minutes before activating the compressor if the heating or cooling system experiences a power loss. Additionally, it will impose a minimum 5-minute delay between cooling and heating cycles.

This feature is designed to protect the compressor from short cycling, although some compressors may already have a built-in time delay and may not require this specific feature. Checking with your compressor manufacturer can clarify whether the lockout feature is already incorporated into their system.

Both snowflake and flame Icon solid display

When your thermostat is configured to automatically heat and cool your space, a solid snowflake and flame icon will prominently display. This signifies that the thermostat is operating in the “Auto” mode. In this mode, the thermostat seamlessly transitions between heating and cooling as needed, responding to both the temperature settings you’ve defined and the ambient temperature conditions. This automated approach ensures optimal comfort within your space by dynamically adjusting between heating and cooling modes as required.❄️

Solid flame icon (System is in Heat Mode)

When your thermostat is set to the “Heat ” mode, a solid flame icon will prominently display, indicating that the heating system is actively engaged. In this mode, the thermostat exclusively triggers the heating system to generate warmth and sustain the desired temperature within your space. This clear visual cue assures you that the thermostat is dedicated to providing a comfortable and warm environment during colder periods. 🔥🌡️
