Common Causes
The Honeywell thermostat is a popular choice for many homeowners. Sometimes, the ‘Heat On’ light may start blinking. This can be a sign of various issues. Understanding the common causes can help you troubleshoot the problem.
Power Issues
One common cause is power issues. The thermostat may not be getting enough power. Check if the batteries are low. Replace them if needed. Also, check the circuit breaker. It might have tripped. Reset it if necessary.
Wiring Problems
Wiring problems can also cause the ‘Heat On’ light to blink. Loose or damaged wires may disrupt the connection. Inspect the wiring behind the thermostat. Ensure all wires are properly connected. If you find any damaged wires, replace them.
Resetting The Thermostat
Is your Honeywell Thermostat Heat On Blinking? Resetting it can often fix many common issues. Here, you will learn how to reset the thermostat manually and perform a factory reset.
Manual Reset
Performing a manual reset is simple and takes a few steps:
- Turn off the thermostat.
- Flip the circuit breaker to off.
- Wait for 30 seconds.
- Turn the circuit breaker back on.
- Turn on the thermostat.
This process will help reset the thermostat without losing any settings. It can resolve minor glitches and restore normal operation.
Factory Reset
A factory reset returns the thermostat to its original settings. Use this option if manual reset does not work:
- Press and hold the menu button.
- Select ‘Reset’ from the menu.
- Choose ‘Factory Reset.’
- Confirm your choice.
After a factory reset, you need to reconfigure all settings. This includes setting up your heating and cooling preferences again.
Both reset methods can resolve the blinking heat light issue. Choose the method that best suits your needs.
Checking The Wiring
When your Honeywell thermostat shows a blinking “Heat On” message, it can be frustrating. The issue may often be traced to wiring problems. Ensuring all connections are in place and secure is crucial. Let’s explore how to inspect and fix the wiring.
Inspect Connections
First, turn off the power to the thermostat. This ensures safety while working with electrical components. Remove the thermostat cover to access the wiring. Carefully examine each wire.
- Check for any loose wires.
- Look for wires that are not connected.
- Ensure wires are not damaged or frayed.
If you find any issues, it’s essential to address them before proceeding. Wires that are not properly connected can cause the thermostat to malfunction.
Tightening Loose Wires
If you discover any loose wires, tighten them carefully. Use a screwdriver to secure the connections. Ensure each wire is firmly connected to its terminal.
- Hold the wire close to the terminal.
- Insert the wire into the terminal slot.
- Use a screwdriver to tighten the screw.
Repeat these steps for each loose wire you find. Properly connected wires ensure the thermostat functions correctly.
By inspecting and tightening the wiring, you can resolve many issues that cause the “Heat On” light to blink. This simple check can save you time and prevent further problems.
Power Supply Problems
If your Honeywell thermostat displays a blinking “Heat On” message, power supply problems might be the cause. A steady power supply is crucial for the thermostat’s performance. Any disruption can lead to issues. In the case of a blinking “Heat On” message, check for common power supply problems first.
Tripped Circuit Breaker
A tripped circuit breaker can cause the thermostat to malfunction. Go to your electrical panel and look for any tripped breakers. If you find one, reset it. This simple step might solve the issue. Always ensure the breaker stays in the “On” position. If it trips again, there could be an underlying problem. In that case, consult a professional electrician.
Blown Fuse
A blown fuse can also cause power supply issues. Check the fuse box for any blown fuses. Replace any that appear damaged. Ensure you use a fuse with the correct rating. This helps maintain a steady power supply. If the fuse keeps blowing, it indicates a more serious issue. Seek help from a qualified technician to avoid further damage.
Furnace Issues
Dealing with a Honeywell thermostat’s “Heat On” blinking issue can be stressful. Often, this problem points to furnace issues. Understanding these furnace-related problems can help you troubleshoot and resolve them quickly.
Pilot Light
The pilot light in your furnace is crucial. It ignites the gas to produce heat. If your pilot light is out, your Honeywell thermostat may blink “Heat On.” Check if the pilot light is lit. If it is not, it could be due to a draft or a dirty pilot tube. You can try relighting it according to the manufacturer’s instructions.
Sometimes, the pilot light goes out frequently. This can indicate a more serious issue. For example, a faulty thermocouple might be the cause. The thermocouple ensures the pilot light stays lit. If it is defective, the pilot light will not stay on.
Gas Valve
The gas valve controls the flow of gas to your furnace. If the gas valve is off or malfunctioning, your thermostat may blink “Heat On.” First, ensure the gas valve is open. You can usually find it near the gas line leading to your furnace.
If the gas valve is open and the issue persists, the valve might be faulty. In this case, you should contact a professional. A defective gas valve can cause serious safety concerns. It is essential to address it promptly.

Thermostat Settings
Understanding your Honeywell thermostat settings can help solve many issues. One common problem is the Heat On light blinking. Adjusting the settings correctly can fix this. Let’s dive into the essential thermostat settings.
Correct Mode
First, ensure your thermostat is in the correct mode. For heating, it should be set to Heat. Check the display panel. If it shows Cool or Off, adjust it to Heat.
| Mode | Function |
|---|---|
| Heat | Activates heating system |
| Cool | Activates cooling system |
| Off | System is off |
Temperature Calibration
Next, check the temperature calibration. Sometimes, the thermostat may show the wrong temperature. This can cause the Heat On light to blink. Use a separate thermometer to check the room temperature. Compare it with the thermostat reading.
- If they match, the calibration is correct.
- If they differ, follow the user manual to recalibrate.
Proper calibration ensures your Honeywell thermostat works efficiently. This small step can make a big difference in your comfort.
Software Updates
Software updates are crucial for your Honeywell thermostat’s performance. They ensure the device runs smoothly and efficiently. Regular updates can fix bugs and improve functionality. This section focuses on important aspects of software updates for Honeywell thermostats.
Firmware Upgrade
Firmware upgrades can enhance your thermostat’s capabilities. These upgrades often include new features. They also address any existing issues. To check for updates, access the settings menu on your thermostat. Follow the on-screen instructions for the upgrade process.
Compatibility Check
Ensure your thermostat is compatible with the latest firmware. Older models might not support new updates. Check the user manual or Honeywell’s website for compatibility details. This step can prevent potential issues during the update process.
Professional Help
Sometimes, the blinking heat on your Honeywell thermostat means something serious. If you’ve tried troubleshooting and nothing works, it might be time to call a professional. Expert help can save you time and ensure the problem is fixed correctly.
When To Call A Technician
There are certain situations when calling a technician is necessary. Here are some signs:
- Constant Blinking: If the thermostat keeps blinking for hours.
- No Heat: If your home doesn’t warm up despite the heat setting.
- Strange Noises: If you hear unusual sounds from your heating system.

These issues might indicate a deeper problem. A technician can diagnose and fix these problems efficiently.
Choosing The Right Service
Finding the right service is crucial. Here are some tips:
- Check Reviews: Look for services with positive customer feedback.
- Ask for Certification: Ensure the technician is certified to handle Honeywell thermostats.
- Get Quotes: Compare prices from different services to find a fair deal.
