Why Is My Heater Not Working?

January 31, 2023 | Blog

Most of today’s air systems are reliable and modernized, but they all deal with problems, eventually. If a failing heater has your family bundled in blankets, it’s important to repair the unit quickly.

Foulks Southern Air Heating & Cooling is here to help you and your family stay warm this winter. We help Hammond homeowners keep their air systems working all year round! To figure out what issues may cause your heater to fail, read on to learn more.

Thermostats Can Cause Heating System Problems

Your heater relies on the thermostat to regulate how much heat it needs to produce. If you haven’t set your thermostat properly, or turned it on at all, your home won’t receive heat. It’s simple, but make sure that you’ve programmed your thermostat properly for the new season.

Today’s thermostats are quite hardy, but all thermostats eventually have issues that emerge. If this is the case, it will probably need repairs or a full replacement. Reach out to our team to schedule your service today!

Forgetting Furnace Tune-Ups

Just like changing your car’s oil every few thousand miles, you have to service your heater, too! Your heater needs to be serviced annually to make sure that the system is clean and problem-free.

It’s extremely common for heaters to stop turning on if they haven’t been serviced in a long time. If your furnace hasn’t been tuned and it won’t turn on, the system is probably dirty. There are many elements within the unit that can cause issues, so it can be difficult for a DIY-er to pinpoint the part that’s causing the system to fail.

For most of these fixes, it’s safest to schedule a professional furnace repair. Our team is ready to maintain your home’s heater, so don’t delay – contact us to schedule your tune-up!

The Blower

A dirty blower can easily cause equipment failure. The system’s heat exchanger relies on the blower to keep it from overheating. If the blower is grimy and impeding the airflow, it can cause the system to fail.

Cleaning the blower usually isn’t a do-it-yourself task. The piece will need to be thoroughly cleaned, because a light dusting won’t fix the issue. Plus, a professional technician will need to check that the dirt has not damaged the blower motor. It’s best to call your trusted heating and cooling company for this one!

The Air Filters

The heating system’s filter protects the unit from debris, dust and other pollutants in your air. Filters work to keep the air entering your unit, and your home, clean. If the filters are dirty, they restrict essential airflow, causing the heat exchanger to overheat and your system to shut down.

Changing your filters every 3 months can help prevent system failures. Although you’ll still need to get a professional heater tune-up annually, changing your filters will help get your system running again.

The Flame Sensor And Burners

This piece makes it possible for your unit to light the burners and heat the air. If grime is covering the sensor, your unit won’t be able to sense a flame, so it shuts down to prevent gas emissions. Similarly, the burners may be too dirty to operate safely. In this instance, the burners will shut themselves off and your furnace won’t be able to produce heat.

An HVAC technician can help with both issues and check that the rest of your unit is operating as it should.

A Dead Capacitor

Your unit’s blower capacitor looks like a huge battery attached to the furnace. It works like a battery, too, because it starts the system once your thermostat gives it a signal. If this part is failing, then your blower won’t function properly and your system will shut down.

If your capacitor is failing, it needs to be replaced. However, only a heater repair company or electrician should replace this part.

Low Refrigerant Levels For Heat Pumps

Heat pumps rely on refrigerant to complete their air cycle, and these levels can get too low. When the refrigerant level is too low for too long, the compressor can overheat and fail.

The easiest solution is to recharge your refrigerant, but this isn’t a task for handy homeowners. You’ll need a certified HVAC technician to recharge your system to restore the refrigerant to proper levels. Refrigerant is extremely dangerous – do not attempt to work with this product yourself. Let our trained team repair refrigerant line damage and recharge your system.
