Why Is There a Blinking Red Light on My Furnace?
Seeing a blinking red light on your furnace can be concerning. Understanding the possible causes of this problem will help you determine what steps you need to take to address it. Learn more about this issue with the help of a home heating repair expert.
Low Voltage
One of the most common reasons there is a blinking red light on furnaces is low voltage. This scenario can happen if there is a recent power outage or surge in your area. It could also occur when you’ve recently added new appliances to the circuit that powers your HVAC system. A voltmeter can measure the incoming electrical current at both ends of the power line. If the readings are lower than normal, you need an electrician to balance out the voltage levels of your home’s electrical system.
System Malfunction
A system malfunction can cause your furnace could be to blame for the blinking red light. HVAC maintenance companies can diagnose this issue and help you. At Stone Heating and Air, our experienced technicians will assess your unit to determine whether it needs repairs or replacement.
Dirty Filter
Another common cause of a blinking red light is a dirty filter. HVAC filters usually require replacement every three months, depending on the type. You may need to replace yours more frequently if someone in the family has allergies or asthma.
Moreover, clogged air filters can restrict airflow, which can cause the system to overheat. You can easily avoid this problem by keeping up with your filter replacement schedule. It also helps to schedule routine HVAC tune-ups.
Clogged Drain Line
The drain line may be clogged if the air filter is not the problem. Obstructed drain lines will cause condensation and water inside the unit, eventually causing a short circuit. Regular cleaning of the drain line can help prevent this problem.
