Initial Checks
Before diving deep into complex troubleshooting, start with initial checks. These simple steps can save time and effort. They often resolve common issues with your Ducane furnace.
Thermostat Settings
Ensure the thermostat settings are correct. Set the thermostat to “heat” mode. Verify the temperature setting is higher than the room temperature.
- Check the display for any error messages.
- Replace the batteries if the display is blank.
- Make sure the thermostat is clean and free from dust.
Power Supply
Confirm the power supply to your furnace. Check the circuit breaker panel. Ensure the breaker for the furnace is not tripped.
If the breaker is tripped:
- Turn the breaker to the “off” position.
- Wait for a few seconds.
- Turn it back to the “on” position.
If the furnace still does not power on, check the fuse near the furnace unit. Replace it if necessary.
Also, inspect the power switch on the furnace. Ensure it is in the “on” position.
| Check | Action |
|---|---|
| Thermostat | Set to heat, adjust temperature, replace batteries. |
| Breaker | Reset breaker, check and replace fuse. |
| Power Switch | Ensure it is turned on. |
Filter Problems
Experiencing issues with your Ducane furnace? Filter problems could be the cause. Filters play a crucial role in maintaining your furnace’s efficiency. They trap dust, debris, and other particles, ensuring clean air circulates through your home. Understanding common filter issues can help you troubleshoot and maintain your furnace.
Clogged Filters
Clogged filters restrict airflow, reducing your furnace’s efficiency. This can cause the furnace to overheat and shut down. Regularly checking and cleaning filters is essential to prevent this issue.
- Inspect filters every month.
- Clean or replace dirty filters immediately.
- Ensure proper airflow to avoid overheating.
A dirty filter can also increase your energy bills. Your furnace works harder, consuming more power. Keeping filters clean helps maintain optimal performance and efficiency.
Filter Replacement
Replacing filters at regular intervals is crucial. It ensures your furnace operates smoothly. Follow the manufacturer’s guidelines for filter replacement.
- Turn off the furnace before replacing the filter.
- Locate the filter compartment.
- Remove the old filter carefully.
- Insert a new filter of the correct size.
- Secure the filter compartment and turn the furnace back on.
Using the correct filter size and type is vital. An incorrect filter can lead to improper airflow and furnace issues.
Regular filter maintenance is key to a well-functioning furnace. Keep an eye on filter conditions and replace them when necessary. This simple task can save you from bigger problems and costly repairs.

Ignition Issues
Ignition issues in Ducane furnaces can cause a lot of headaches. When your furnace fails to ignite, it can leave you in the cold. To help you troubleshoot these problems, we will discuss two common issues: Pilot Light Problems and Electronic Ignition Failures.
Pilot Light Problems
Pilot light problems are a common issue in older furnaces. If the pilot light goes out, the furnace will not ignite. Here are some common causes and solutions:
- Dirty Pilot Orifice: Use a needle to clear out the orifice.
- Thermocouple Issues: Check if the thermocouple is in position. Replace if damaged.
- Gas Supply: Ensure the gas valve is open. Check for gas supply issues.
Electronic Ignition Failures
Modern furnaces use electronic ignition systems. These systems are more reliable but can still fail. Here are some common electronic ignition issues:
- Ignitor Malfunction: Inspect the ignitor for cracks. Replace if necessary.
- Flame Sensor Issues: Clean the flame sensor with a fine cloth. Replace if it’s faulty.
- Control Board Problems: Check for error codes. Consult the manual for troubleshooting steps.
Blower Motor Troubles
The blower motor in your Ducane furnace plays a crucial role. It circulates warm air throughout your home. However, it can sometimes run into problems. This guide will help you with common blower motor troubles.
Noisy Motor
A noisy blower motor can be annoying. It can also indicate a serious issue. Here are some common causes and solutions:
| Cause | Solution |
|---|---|
| Loose components | Tighten screws and bolts |
| Worn bearings | Lubricate or replace bearings |
| Debris in the motor | Clean the motor area |
If the motor is still noisy, it might need replacement. Always consult a professional for this.
Motor Not Running
If the blower motor is not running, it can cause major issues. Here are some steps to troubleshoot:
- Check the power supply: Ensure the furnace is plugged in and the breaker is on.
- Inspect the thermostat: Make sure it is set to “Heat” and the temperature is high enough.
- Examine the blower door switch: This safety switch must be engaged for the motor to run.
- Test the motor: Use a multimeter to check for power reaching the motor.
If these steps do not fix the issue, the motor might be faulty. Contact a professional for further inspection.
Flame Sensor Cleaning
Flame sensors are crucial components in Ducane furnaces. They detect the flame and ensure the furnace functions safely. Over time, flame sensors can get dirty, causing the furnace to malfunction. Cleaning the flame sensor can restore proper functionality.
Identifying Flame Sensor
First, turn off the furnace power. Locate the furnace panel and remove it. The flame sensor is a thin, metallic rod situated near the burner.
The sensor usually has a single wire attached to it. Ensure the furnace is completely off before proceeding.
Cleaning Steps
- Turn off power: Ensure the furnace is off to avoid electric shock.
- Locate the sensor: Find the sensor near the burner. It looks like a small, thin rod.
- Remove the sensor: Unscrew the flame sensor carefully. Disconnect the wire attached to it.
