If you have a furnace that is not blowing air, you might want to consider taking some steps to fix the problem. You should start by checking the thermostat. Make sure that it is set to “heat” and has a temperature of at least five degrees above the room’s air temperature. It may also be worth changing your air filter.
A dirty air filter will restrict air flow. This can lead to your furnace turning on and off too quickly. Your filter should be changed every three months on most residential heating systems. Changing the filter will help to prevent the buildup of contaminants. However, if this does not fix your problem, you should contact a technician.
Another common cause of your furnace not working is a broken thermostat. You can check your thermostat for loose wires and breaks. Also, make sure that the thermostat is level and firmly attached to the wall. If it is not, you should consider rewiring it.
Your furnace might have a faulty ignitor or sensor. These can be replaced with a new part. Be careful not to damage anything while you are replacing the parts. You can read your user’s manual for a step-by-step procedure.
Another common cause of your furnace not blowing air is an obstruction. You should clear the intake vents and the fresh-air ducts to ensure that there is no blockage. Other problems can include a bad gas control valve or a malfunctioning blower motor. The blower motor can be a symptom of more serious problems. Typically, a professional is the best choice for fixing your furnace.
If your thermostat is still displaying the “low battery” warning, you should replace the batteries. Most programmable thermostats will display a low-battery icon. Some will even have an error code. Check your thermostat to see what the error code is.
A circuit breaker will need to be reset before you can begin any repair. Check the breaker panel in your home to find the circuit breaker for your furnace. Once the breaker is reset, turn it back on.
If your furnace is still not blowing air, try cleaning the ignitor or sensor. You can clean these with furnace not working medium-grain sandpaper. When you’re finished, you can test the system to make sure that everything is working properly.
A fuse on your furnace might be blackened or blown. You can remove it with a screwdriver. While it’s easy to fix, it may be indicative of a larger electrical system problem. Replace the fuse with a new one.
In addition to the above, you should check your gas controls and switch. A tripped breaker could be a sign of a short in the wiring. Depending on your furnace’s make and model, you may need to consult with a professional.
Whether you’re repairing your furnace yourself or hiring a pro, it’s important to remember that your furnace is an important piece of equipment. Having a clear understanding of the mechanics of your HVAC system can keep you comfortable and save you money on your heating and cooling bills.
