It’s the greatest fear of many Elkhart homeowners: Arctic blasts drop temperatures to subzero and your furnace won’t turn on. This isn’t just an issue of discomfort. A heating breakdown in extreme weather can lead to everything from burst pipes to potential carbon monoxide exposure.
In this article, the HVAC experts at Church Plumbing discuss why your furnace might fail, along with signs to watch for and how to respond to protect your health and safety this winter.
Why Furnaces Fail
Furnaces fail for a variety of reasons that range from dirty components to dangerous gas line issues. While problems are bound to occur as your system ages due to normal wear and tear, homeowners can avoid emergency breakdowns with maintenance and early repairs. In the following sections, we cover common causes of furnace failures, along with what you can do to restore your heat quickly.
Thermostat Problem
If your thermostat can’t properly communicate to your furnace or isn’t reading your home temperature correctly, your furnace won’t turn on. A blank screen or a thermostat that is unresponsive may simply require new batteries. Once you’ve done this, ensure the system is set to “heat” and the desired temperature is higher than the current room temperature. If this doesn’t solve the problem, call for emergency thermostat repairs.
Frozen Intake Vents
In the cold Elkhart winters, it’s common for your furnace’s intake vents to freeze and may cause your system to make loud whooshing sounds. Homeowners can check the outdoor pipes for snow, ice, or blockages and attempt to clear them by hand or with warm water. If clearing the ice doesn’t restore your heat, you may need professional repairs.
Ignition Issues
When your furnace won’t ignite or makes a clicking sound without ignition, you’ll need urgent help. Improper combustion or other ignition issues can put you at risk for carbon monoxide hazards. Attempt to get the system on by replacing dirty air filters and resetting the system. If this doesn’t work or if you smell a gas scent, leave immediately and call for emergency help.
Gas Supply Issue
Weak heat or clicking sounds can also signal a gas supply issue. Check if other gas appliances like stoves or dryers are working. If they aren’t, the problem may be bigger. These types of utility issues should be handled urgently. If you smell gas or suspect a leak, leave your home and call 911.Â
Disconnected Power Supply
A furnace that is completely unresponsive may have a power issue. Check the furnace power switch and for a tripped breaker. If you reset the breaker and it trips again, there could be a dangerous electrical fault. Call a professional for repairs, especially if you see scorch marks, experience burning smells, or if the furnace remains dead even after you’ve verified it has proper power.
