Troubleshooting Guide: Propane Furnace Blowing Cold Air

Recent Posts


Dear homeowners, if you find yourself in a situation where your propane furnace is blowing only cold air, worry not! MS Propane is here to guide you through a step-by-step troubleshooting process to help restore warmth to your home.

Check Thermostat Settings

Begin by checking your thermostat settings. Ensure that the thermostat is set to the desired temperature and is in heating mode. If the thermostat batteries are replaceable, consider replacing them.

Inspect the Pilot Light

For furnaces with a pilot light, check to see if it is lit. If it’s out, follow the manufacturer’s instructions to relight it. If you’re unsure or uncomfortable doing this, contact a qualified technician.

Examine the Air Filter

A clogged or dirty air filter can impede proper airflow, causing the furnace to blow cold air. Check the air filter and replace it if it’s dirty. Regularly changing the filter is essential for optimal furnace performance.

Verify Propane Supply

Ensure that there is an adequate supply of propane to your furnace. Check the propane tank gauge and verify that the gas valve is open. If the tank is low, consider refilling it. If the tank is empty, contact your propane supplier to arrange a refill.

Inspect the Thermostat Wiring

Examine the thermostat wiring for any loose or disconnected wires. If you notice any issues, turn off the furnace and consult your thermostat’s manual or seek professional assistance.

Reset the Furnace

Some furnaces have a reset button. If your furnace has one, try resetting it. Refer to the manufacturer’s instructions on how to properly reset your specific furnace model.

Professional Inspection

If the troubleshooting steps do not resolve the issue, it’s time to enlist the expertise of a qualified HVAC technician. They can diagnose and address more complex problems, ensuring your propane furnace operates efficiently.

Remember, safety is paramount. If you encounter a situation that seems beyond your capability or involves potential hazards, contact a professional immediately. Your comfort and safety are our top priorities at MS Propane.
