Initial Checks
When experiencing issues with your Coleman Evcon furnace, start with some initial checks. These simple steps might resolve common problems. Before calling a professional, go through these checks to potentially save time and money.
Thermostat Settings
The thermostat controls your furnace. Ensure it is set correctly. First, check if the thermostat is set to heat mode. If it is in cool mode, the furnace will not start.
Next, verify the temperature setting. Set it at least five degrees higher than the current room temperature. This ensures the furnace has a clear signal to turn on.
Look at the thermostat display. If it is blank, replace the batteries. A weak battery can cause the thermostat to malfunction.
Power Supply
Your furnace needs power to operate. Ensure the power switch is turned on. The switch is usually located near the furnace on the wall.
Check the circuit breaker or fuse box. A tripped breaker or blown fuse can cut off power. Reset the breaker or replace the fuse if necessary.
Inspect the power cord. Ensure it is plugged in securely. Look for any signs of damage or wear.
If your furnace has a power indicator light, ensure it is on. A lit indicator confirms power is reaching the furnace.
| Check | Action |
|---|---|
| Thermostat Mode | Set to Heat |
| Temperature Setting | Set Higher than Room Temperature |
| Thermostat Display | Replace Batteries if Blank |
| Power Switch | Ensure it is On |
| Circuit Breaker | Reset if Tripped |
| Power Cord | Check for Secure Connection |
| Power Indicator Light | Ensure it is Lit |
Furnace Not Igniting
When your Coleman Evcon furnace fails to ignite, it can disrupt your home’s comfort. Understanding the common issues can help you troubleshoot effectively. Below are some frequent causes and solutions.
Pilot Light Problems
The pilot light ignites the furnace burners. If it’s not working, your furnace won’t start.
- Check the Pilot Light: Ensure it’s lit. If not, relight it.
- Inspect for Obstructions: Dust or debris can block the pilot light.
- Thermocouple Issues: The thermocouple might be faulty. Replace it if needed.
Ignitor Faults
The ignitor creates the spark to ignite the gas. A faulty ignitor means no heat.
| Common Issues | Solutions |
|---|---|
| Dirty Ignitor | Clean the ignitor gently with a soft brush. |
| Cracked Ignitor | Replace the ignitor if it’s cracked or broken. |
| Electrical Issues | Check wiring connections. Ensure they are secure. |
Address these common issues to get your furnace igniting again. Regular maintenance can prevent these problems.
Blower Motor Problems
Experiencing issues with your Coleman Evcon furnace? A common problem is the blower motor. The blower motor is crucial for circulating warm air through your home. If it’s not working properly, your furnace can’t function efficiently.
Motor Not Running
If your blower motor is not running, start by checking the power source. Make sure the furnace is plugged in and the circuit breaker is not tripped. Inspect the thermostat to ensure it’s set to the correct temperature.
Follow these steps:
- Verify power supply to the furnace.
- Ensure thermostat settings are correct.
- Check for any blown fuses in the furnace.
- Look for any visible wiring issues.
If these steps don’t resolve the issue, the problem might be internal. In such cases, it’s best to call a professional technician.
Strange Noises
Strange noises from the blower motor can indicate various issues. Listen for any unusual sounds like grinding, squealing, or banging.
Common causes include:
- Loose parts: Check for any loose components and tighten them.
- Debris: Ensure there’s no debris obstructing the motor.
- Worn bearings: Bearings may need lubrication or replacement.
Addressing these noises early can prevent more serious damage. Regular maintenance helps keep your blower motor running smoothly.
Use this troubleshooting table to diagnose noises:
| Noise Type | Possible Cause | Solution |
|---|---|---|
| Grinding | Worn bearings | Lubricate or replace bearings |

Proper maintenance and timely repairs ensure your Coleman Evcon furnace operates efficiently.
Airflow Issues
Airflow issues can cause your Coleman Evcon Furnace to work poorly. These issues lead to uneven heating and higher energy bills. Let’s look at two common airflow problems: Clogged Filters and Blocked Vents.
Clogged Filters
Clogged filters block the airflow in your furnace. This makes your furnace work harder. It also reduces the lifespan of your furnace.
To check for clogged filters, follow these steps:
- Turn off your furnace.
- Locate the filter compartment.
- Remove the filter.
- Inspect the filter for dirt and debris.
- If dirty, replace the filter with a new one.
It’s best to check your filters every month. This helps to maintain good airflow.
Blocked Vents
Blocked vents can stop warm air from spreading in your home. This can make some rooms colder than others.
To fix blocked vents:
- Ensure furniture is not blocking the vents.
- Check for dust or debris inside the vents.
- Clean the vents using a vacuum cleaner.
Keeping vents clear allows for proper airflow. This helps your furnace work efficiently.
Here is a table summarizing the steps:
| Issue | Steps |
|---|---|
| Clogged Filters |
|
| Blocked Vents |

- Use a screwdriver to adjust the screw.
- Recheck the temperature readings.
If recalibration fails, replace the thermostat. An accurate thermostat ensures your furnace runs efficiently.
Wiring Problems
Wiring problems can disrupt the thermostat’s connection to the furnace. Inspect the thermostat wires for any signs of damage. Look for frayed or broken wires. Ensure all connections are tight and secure.
Here are common wiring issues:
- Loose connections
- Corroded wires
- Incorrect wiring setup
Use the furnace’s manual to verify the wiring layout. If unsure, contact a professional technician. Proper wiring is crucial for thermostat functionality.
Below is a table summarizing common thermostat wiring problems and their solutions:
| Problem | Solution |
|---|---|
| Loose connections | Tighten the wire connections |
| Corroded wires | Clean or replace the wires |
| Incorrect wiring setup | Refer to the manual for correct setup |
Gas Supply Concerns
Facing issues with your Coleman Evcon furnace? Gas supply problems might be the cause. Addressing these concerns ensures your furnace works efficiently. This section focuses on troubleshooting gas supply issues, including gas valve problems and supply line checks.
Gas Valve Issues
The gas valve controls the gas flow to the furnace. A malfunctioning valve can disrupt this flow. Ensure the valve is set to the “on” position. If the valve is open but there’s no gas flow, the valve might be faulty.
Here’s how to check the gas valve:
- Locate the gas valve near the furnace.
- Ensure the valve is not obstructed.
- Check for any unusual sounds.
- Test the valve with a multimeter for continuity.
If the valve shows no continuity, replace it immediately. This ensures a continuous gas supply to the furnace.
Supply Line Checks
The supply line delivers gas from the main supply to the furnace. Issues in this line can halt the gas flow. Inspect the supply line regularly for any visible damage.
Steps to inspect the supply line:
- Turn off the gas supply.
- Check the entire line for cracks or leaks.
- Use a soapy water solution to find leaks.
- Apply the solution to the line and watch for bubbles.
If bubbles appear, there’s a leak. Repair or replace the damaged section immediately. A secure supply line ensures uninterrupted gas flow.
Regular checks and timely repairs maintain your Coleman Evcon furnace’s efficiency. Address gas supply concerns promptly to enjoy a warm, comfortable home.
