- Blocked Vents: Make sure the vents are open and unblocked.
- Thermostat Malfunction: The thermostat might not be reading the temperature correctly.
Addressing these issues can often restore your furnace to proper working condition.
Furnace Won’t Turn On
Finding that your Concord furnace won’t turn on can be frustrating. It’s a common issue many homeowners face. Let’s dive into some possible reasons and how you can troubleshoot them effectively.
Thermostat Issues
One of the first places to check is your thermostat. If it’s not working properly, your furnace won’t turn on.
- Make sure the thermostat is set to “heat”.
- Check the temperature setting. It should be higher than the room temperature.
- Replace the batteries if needed.
- Ensure the thermostat is clean and free from dust.
Sometimes, the wiring can be a problem. Loose or corroded wires might prevent the thermostat from functioning correctly. Inspect the wires and ensure they are connected securely.
Power Supply Problems
If the thermostat is fine, the issue might be with the power supply.
- Check if the furnace switch is on.
- Verify the circuit breaker. It should not be tripped.
- Ensure the fuse is intact. Replace it if necessary.
Sometimes, the furnace might have a reset button. Press it to see if the furnace starts. If there is no power, your furnace won’t turn on.
By following these steps, you can identify why your Concord furnace won’t turn on. This will help you solve the problem quickly and efficiently.
Strange Noises
Strange noises coming from your Concord furnace can be alarming. These sounds often indicate underlying issues. Addressing them promptly can prevent bigger problems. In this section, we will explore two common types of noises: rattling and squealing.
Rattling Sounds
Rattling sounds may signal loose components. Check the furnace panels first. Loose screws can cause vibrations. Tighten any loose screws you find. The issue might also come from the blower motor. Inspect it for any signs of wear or damage. Replace worn-out parts if necessary. Don’t ignore these sounds. They can lead to more serious damage if left unchecked.
Squealing Noises
Squealing noises usually point to belt issues. The blower belt might be worn out or misaligned. Inspect the belt for any signs of fraying. Replace it if needed. Another cause could be the motor bearings. Lubricate the bearings to reduce the noise. Proper maintenance helps keep your furnace running smoothly. If the noise persists, consult a professional technician.
Cycling On And Off
Is your Concord furnace cycling on and off frequently? This issue can be frustrating and impact your home’s comfort. Let’s explore some common causes and troubleshooting tips.
Clogged Air Filters
One of the most common reasons for frequent cycling is clogged air filters. When filters are dirty, air cannot flow freely, causing your furnace to overheat and shut down.
To check your air filter:
- Turn off your furnace.
- Locate the air filter compartment.
- Remove the filter and inspect it.
If the filter looks dirty or clogged, replace it with a new one. This simple step can solve the cycling issue.
Thermostat Malfunctions
Another common issue is thermostat malfunctions. If the thermostat is not working correctly, it can cause your furnace to turn on and off unexpectedly.
To troubleshoot your thermostat:
- Check the thermostat settings. Ensure it is set to the correct mode.
- Replace the batteries if needed.
- Ensure the thermostat is clean and free from dust.
If the issue persists, you might need to replace the thermostat.
Pilot Light Problems
Your Concord furnace’s pilot light is crucial for proper operation. Pilot light problems can lead to heating issues. Two common issues are the pilot light that won’t stay lit and a yellow pilot light.
Pilot Light Won’t Stay Lit
If your pilot light won’t stay lit, it can be frustrating. This issue might be due to:
- A dirty or clogged pilot orifice
- A faulty thermocouple
- Insufficient gas supply
To troubleshoot, follow these steps:
- Turn off the gas and wait a few minutes.
- Clean the pilot orifice with a needle.
- Check the thermocouple connection and tighten if needed.
- Ensure the gas valve is fully open.
If the problem persists, consider calling a professional technician.
Yellow Pilot Light
A yellow pilot light indicates incomplete combustion. This can be dangerous. Common causes include:
- Dirty burner
- Insufficient air supply
- Improper gas pressure
Here’s how you can address it:
- Clean the burner to remove any dirt.
- Ensure the area around the furnace is clear for proper air flow.
- Check the gas pressure and adjust if necessary.
A blue pilot light is ideal. If your pilot light remains yellow, seek professional help.

Blower Issues
The blower in your Concord furnace plays a crucial role. It helps circulate air. If the blower has problems, the furnace won’t work well. There are two main issues: the blower running continuously or not working at all.
Blower Running Continuously
A blower running continuously can be frustrating. Here are common reasons for this issue:
- Thermostat Settings: Check if the fan setting is on “ON”. If so, the blower will run non-stop.
- Fan Limit Switch: A faulty fan limit switch can cause continuous running. Inspect and replace if necessary.
To fix, ensure the thermostat is set to “AUTO”. Replace the fan limit switch if it’s broken.
Blower Not Working
A blower not working means no air circulation. This could be due to:
- Blown Fuse: Check the furnace fuse. Replace if it is blown.
- Motor Problems: The motor might be burned out. Replace or repair if needed.
Ensure the fuse is intact. If the motor is damaged, contact a professional for repairs.
Thermostat Troubles
Is your Concord furnace not heating properly? The issue might be with the thermostat. This small device controls the temperature in your home. Problems with the thermostat can cause incorrect temperature readings or make it unresponsive. Let’s explore these common thermostat issues and how to fix them.
Incorrect Temperature Readings
Sometimes, the thermostat might show the wrong temperature. This can lead to your furnace not turning on or off as needed. Here are some reasons why this might happen:
- Location of the Thermostat: If the thermostat is near a heat source or in direct sunlight, it may give incorrect readings.
- Dirty Thermostat: Dust inside the thermostat can affect its sensors.
- Calibration Issues: Over time, thermostats can fall out of calibration.
To fix these issues, try the following:
- Move the thermostat to a central location away from direct heat or sunlight.
- Carefully clean the inside of the thermostat with a soft brush.
- Check the user manual to recalibrate the thermostat or call a professional.
Unresponsive Thermostat
An unresponsive thermostat can cause your furnace to stop working. If you press buttons and nothing happens, consider these potential causes:
| Cause | Solution |
|---|---|
| Dead Batteries: Batteries in the thermostat may need replacement. | Replace the batteries with new ones. |
| Loose Wiring: Wires can become loose or disconnected. | Check and secure all wiring connections. |
| Software Glitch: Sometimes, the thermostat software might need a reset. | Reset the thermostat according to the manual. |
If the thermostat is still unresponsive after these steps, it might need to be replaced.
