Delayed ignition in a furnace is one of the most common troubleshooting problems for homeowners. The symptoms can vary from a faint gas smell to an unplugged unit to no heat. With these and other symptoms, homeowners may be uncertain why their furnace failed to ignite until it is too late to turn it on. As such, delayed ignition can result in fires if the issue is not dealt with quickly. Here are some of the top reasons why your ignition could be delayed.
1. Mold/Moisture Buildup
One of the most common causes of delayed ignition in a furnace is moisture buildup in the furnace. If the stove is not properly maintained and cleaned regularly, mold can propagate and cause a blockage. The blockage can keep gas from traveling through the ducts to provide heating to your home. The backup will need to be cleaned for the delayed ignition in the furnace to be fixed.
2. Dirt and Debris in the Gas Line
If a furnace is not properly maintained and cleaned, it can accumulate dirt, dust, and debris around the gas line. These materials can quickly build up to block the gas line of your furnace. It will, of course, cause a significant issue with your furnace. The obstructions in the line need to be cleaned or removed as soon as possible to prevent severe damage to your furnace.
3. Duct Dampers
A duct damper is a piece of equipment often left over from installing a furnace to help ensure good airflow through your home. Duct dampers are quickly becoming obsolete as energy-efficient furnaces are installed. However, duct dampers still exist, and many owners fail to maintain them properly or fail to clean or lubricate them at all. These damper valves can cause delayed ignition in a furnace if not maintained.
4. Burned-Out Coils
As furnaces heat and relax, the internal parts can come into contact with gases, dust, and other materials from the air in your home. Over time, these can damage your coils, causing them to break down. It can cause burning, blackening, and, eventually, a complete failure of the furnace.
