Common Furnace Issues
Furnaces are crucial for keeping homes warm during the cold months. Sometimes, they face issues that require troubleshooting. Understanding common furnace problems can help in resolving them quickly. Below are some common issues with Comfortmaker furnaces and tips on how to fix them.
No Heat
If your Comfortmaker furnace is producing no heat, the problem can stem from several sources. Here are a few key areas to check:

Initial Checks
When your Comfortmaker furnace isn’t working, start with some initial checks. These checks can often solve simple issues without needing professional help. Below are some key areas to inspect.
Power Supply
First, ensure your furnace is getting power. A tripped breaker or a blown fuse can be the problem. Check the electrical panel and reset any tripped breakers. If a fuse is blown, replace it with a new one of the same rating.
- Check the furnace switch. This switch is usually on the side of the furnace. Make sure it’s in the “On” position.
- Inspect the power cord. Look for any visible damage. If the cord is damaged, it may need replacement.
Thermostat Settings
Next, check your thermostat settings. Sometimes, the issue is as simple as incorrect settings.
- Ensure the thermostat is set to “Heat”.
- Set the temperature at least 5 degrees higher than the current room temperature.
- Replace the batteries if the thermostat is battery-operated.
- Verify the thermostat is not in “Fan” or “Cool” mode.
If the thermostat is programmable, confirm the schedule settings. Incorrect settings can prevent your furnace from turning on.
Pilot Light Problems
The pilot light is a small flame that ignites the gas in your Comfortmaker furnace. If the pilot light goes out, your furnace won’t produce heat. Understanding common pilot light issues can help you troubleshoot and resolve them quickly.
Relighting The Pilot
If your pilot light is out, follow these steps to relight it:
- Turn off the gas valve and wait five minutes to clear any gas.
- Locate the pilot light assembly. This is usually near the furnace’s bottom.
- Turn the gas valve to the ‘pilot’ position and press the reset button.
- Use a long lighter to ignite the pilot while holding the reset button.
- Release the reset button after 30 seconds and turn the gas valve to ‘on’.
If the pilot light doesn’t stay lit, you may have other issues.
Pilot Light Won’t Stay Lit
If the pilot light won’t stay lit, several factors could be at play:
- Dirty Pilot Orifice: Dirt can clog the pilot orifice, preventing the flame. Clean it with a needle or compressed air.
- Thermocouple Issues: The thermocouple might be faulty. This device senses the pilot light and signals the gas valve. Replace it if necessary.
- Drafts: Strong drafts can blow out the pilot light. Ensure the area around the furnace is free from drafts.
- Gas Pressure: Low gas pressure can cause pilot light problems. Contact your gas supplier if you suspect this issue.
Addressing these issues can help keep your Comfortmaker furnace running smoothly.

Ignition Issues
Experiencing ignition issues with your Comfortmaker furnace can be frustrating. Understanding the specific type of ignition problem can help you diagnose and fix it. Ignition issues usually stem from problems with the electronic ignition or intermittent ignition systems.
Electronic Ignition
Electronic ignition systems are common in modern furnaces. They are more efficient than older pilot light systems. If your furnace isn’t igniting, the issue might be with the electronic ignition.
Here are some common causes and solutions:
- Power Supply: Ensure the furnace is plugged in and the circuit breaker is not tripped.
- Igniter: Check if the igniter is cracked or damaged. Replace if necessary.
- Control Board: Inspect the control board for any visible damage or burnt areas.
Perform these checks carefully. Always turn off the power before inspecting any components.
Intermittent Ignition
Intermittent ignition issues can be tricky. The furnace may ignite sometimes but fail other times. This inconsistency can be due to several factors.
Consider these potential problems:
- Flame Sensor: The flame sensor may be dirty. Clean it with a fine cloth.
- Gas Supply: Ensure that the gas valve is open and the supply is consistent.
- Wiring: Loose or damaged wires can cause intermittent ignition. Inspect and secure all connections.
By identifying these common issues, you can address the problem and restore your furnace to proper working order.
Airflow Problems
Dealing with airflow problems in your Comfortmaker furnace can be frustrating. Proper airflow is essential for efficient heating. It ensures your home stays warm and comfortable. Let’s explore common issues that might be affecting your furnace’s airflow.
Blocked Vents
Blocked vents can restrict airflow in your furnace. Furniture, rugs, or other objects can cover vents. Remove any obstructions to ensure proper air circulation. Dust and debris can also block vents. Regularly clean them to keep air flowing smoothly.
Blower Motor Issues
The blower motor is crucial for moving air through your furnace. If it fails, airflow problems occur. A faulty motor may need repair or replacement. Listen for unusual noises like rattling or humming. These can indicate motor issues. Regular maintenance can prevent blower motor problems.
Strange Noises
Strange noises from your Comfortmaker furnace can be troubling. They often signal issues that need attention. Ignoring these sounds can lead to bigger problems. Understanding these noises can help diagnose and fix the issue. Two common strange noises are rattling sounds and squealing noises.
Rattling Sounds
Rattling sounds often mean loose parts in your furnace. Check the access panels first. They may not be secured properly. Tighten any loose screws. If the rattling continues, inspect the blower motor. Loose bolts or screws can cause rattling here too. The heat exchanger can also cause rattling. Cracks or damage in the heat exchanger are serious. Call a professional if you suspect this issue.
Squealing Noises
Squealing noises usually mean a problem with the blower belt. The belt might be loose or worn out. Check the belt for any signs of damage. If the belt is loose, tighten it. Replace the belt if it shows wear. The blower motor bearings can also cause squealing. Lubricate the bearings to stop the noise. If the noise persists, the motor may need replacement. Professional help is advised in this case.
Filter Maintenance
Proper filter maintenance is essential for the efficient operation of your Comfortmaker furnace. Dirty or clogged filters can cause various issues, affecting your furnace’s performance and air quality. Regular filter maintenance ensures your furnace runs smoothly and efficiently, saving you money on energy bills and costly repairs.
Replacing Filters
Replacing filters regularly is crucial for maintaining your furnace’s efficiency. Check your furnace’s user manual to find the recommended replacement frequency. Typically, it’s every 1-3 months. Ensure you have the correct filter size before purchasing a new one. Turn off the furnace and remove the old filter. Insert the new filter, ensuring it is properly aligned with the airflow direction indicated on the filter. Turn the furnace back on and enjoy improved air quality and performance.
Cleaning Filters
Cleaning reusable filters can extend their lifespan and maintain furnace efficiency. First, turn off the furnace. Remove the filter and inspect it for dirt and debris. Use a vacuum cleaner or a brush to remove loose dirt. For a deeper clean, rinse the filter with water and mild soap. Allow the filter to dry completely before reinstalling it. Regular cleaning will help your furnace run smoothly and improve indoor air quality.
