Air Conditioner Troubleshooting

Coleman makes some of the toughest air conditioners on the market as they make them for homes, RV’s and more! But no matter what kind of AC you have, you’ll eventually run into some problems with it. The good news is that most of the common problems with Coleman air conditioners require only a simple fix. 

The first things you should do also fall under the category of air conditioner maintenance. Even if you’re not having problems with your AC unit, you should do these things regularly anyway. The first thing is to change your filter about once a month. If your filter gets too dirty it can clog the system and affect things like the airflow and efficiency of your system. 

The second thing is making sure the outdoor component of your AC unit is free of debris. Trim all plants nearby and clear leaves and branches, especially during the rainy spring and autumn as the leaves fall. This will ensure that there are no clogs and that the fan isn’t being slowed down. 

Next, if your unit isn’t turning on, then make sure it’s getting power. Usually, this has to do with a circuit breaker issue. If it’s getting power but it isn’t blowing or cooling the way you expect it to, then check the thermostat. Make sure it’s set to “Cool” and that the fan is on. If there’s still a problem, then it could be an issue with the capacitors. If you’re familiar with how to check these then go for it, but if not then now is the time to call your HVAC repair company!

Furnace Troubleshooting

Not heating?  
Either the circuit breaker has shorted or the unit's fuse has blown. Reset the circuit breaker associated with your Coleman furnace. If it's still not heating correctly, you'll want to replace the fuse. 
The igniter has cracked or become defective. Locate the igniter within your Coleman furnace and inspect the part for cracks. If it's damaged then you'll have to replace the part. Otherwise, test it with a multimeter for continuity to see if it's defective. 

Cycling irregularly?  
Your thermostat might be calibrated improperly and as a result, is adjusting incorrectly. Check to see if your thermostat has an adjustable calibration scale, if so then use this to adjust the heat anticipator. If this doesn't appear to work or you don't have a scale, replace the thermostat completely. 

Not blowing hot air?  
The blower motor in your Coleman furnace is either burnt out or it's connecting belt has broken. You'll have to inspect the motor to see if power is reaching it. If it does but the motor continues to function incorrectly, then the blower motor has failed. However, if the motor continues to run, but the air still isn't moving, then the connecting belt has broken. Depending on the situation, you'll have to replace the motor or the belt. 

Blowing too much air?  
The control board is experiencing difficulty. The board's relay that regulates how much voltage is sent to the blower motor is defective. You will have to replace the control board. 
The contact on your thermostat responsible for controlling the blower motor is defective. Use a multimeter to check for continuity, if the thermostat isn't working properly then replace it. 

Starting and then stopping shortly after? 
The flame sensor used to detect whether or not a flame is present requires attention. The sensor has become either dirty or defective. Use a fine abrasive pad to clean the sensor if it appears to be dirty. If it's defective then replace the sensor altogether.

Heat Pump Troubleshooting

Here are some general troubleshooting tips for a Coleman heat pump:

Check the power supply: Ensure that the heat pump is receiving power by checking the circuit breaker or fuse box. If a breaker has tripped or a fuse has blown, reset or replace it accordingly.

Check the thermostat settings: Make sure the thermostat is set to the desired temperature and mode (heat or cool). Verify that the fan setting is appropriate (auto or on) and that the system is not in a temporary hold or vacation mode.

Inspect the air filter: A dirty or clogged air filter can restrict airflow and impact the heat pump's performance. Check the air filter and clean or replace it if necessary. It's generally recommended to clean or replace the filter every 1-3 months.

Check the outdoor unit: Ensure that the outdoor unit is clear of debris, such as leaves, grass, or dirt. Remove any obstructions that may obstruct airflow. Additionally, check if the outdoor coil is clean and free from dirt buildup.

Verify the indoor registers and vents: Ensure that the supply registers and return vents are not blocked or obstructed by furniture, curtains, or other objects. Clear any obstructions to allow proper airflow throughout the system.

Check the condensate drain: If the heat pump has a condensate drain, inspect it for clogs or blockages. A clogged drain can cause water to back up and potentially shut down the system. Clear any obstructions or consult a professional for assistance.

Check for error codes: If the heat pump displays an error code, consult the owner's manual or contact the manufacturer's customer support for guidance on troubleshooting the specific error.

Schedule professional maintenance: Regular professional maintenance is essential for optimal performance and to identify any underlying issues. Consider scheduling annual maintenance with a qualified HVAC technician to ensure your Coleman heat pump operates efficiently.

If you've followed these troubleshooting tips and the issue persists, it's recommended to contact a qualified HVAC technician for further diagnosis and repair. They have the expertise and tools to identify and resolve more complex issues with your Coleman heat pump.
