An overheating Argenta, IL furnace deserves immediate attention. Not only can it cause damage to your entire HVAC system, but it’s also a fire hazard. Check out these four things that can cause your furnace to overheat.
1. The Air Filter Is Dirty
The air filter helps prevent dust and debris from entering the furnace. But if the filter is too dirty, it can become clogged, restricting airflow.
When the furnace doesn’t have adequate airflow, it works harder to heat your home. Even this little bit of extra effort can cause the furnace to overheat. It’s a good idea to check your filter every month and clean or replace it when necessary (or as the manufacturer recommends).
2. Something Is Blocking the Vents
The vents allow hot air to circulate throughout your home. It’s possible to inadvertently block these vents with items such as furniture or carpets. This means the air cannot flow freely, and the furnace will likely run longer and could overheat.
3. The Thermostat Is Faulty
A faulty thermostat can send the wrong signals to the furnace and cause it to overheat. For example, a thermostat that thinks your home is too cold could cause the furnace to run continuously. In that case, it won’t shut off even when you can feel that the home is warm enough, meaning you need a maintenance appointment.
4. The Limit Switch Is Faulty
Your furnace has a limit switch that should stop the furnace from overheating. The switch monitors the temperature inside the furnace and shuts it off if it gets too hot. But if the limit switch is faulty, it might not turn the furnace off before it overheats.
No matter the cause of the problem, it’s always a cause for concern when a furnace overheats. Contact Tica, Inc. Heating and Cooling today to get your overheating furnace performing right again.
