Amana furnaces are reliable HVAC systems that can keep your house warm all winter. With many models to choose from, Amana, a household appliance company, provides everything from central heating units to portable wall units.
Amana HVAC systems are durable, but as every homeowner knows, it is natural for furnaces to break down over time. If you have an Amana furnace, you probably want to know how to troubleshoot any problems with your machine.
In this manual, we identified the most common problems with Amana furnaces (Read also: Amana Furnace Problems: Fix it Here!). We also break down potential solutions so that you can ensure your heat works properly.
Amana Furnace Troubleshooting: Main Problems and Solutions
To troubleshoot issues with your Amana furnace, we have identified the main problems that consistently come up – this ranges from your furnace not heating properly, your vents blowing too much air, to a faulty circuit breaker. We have also provided solutions to common problems so that you learn how to repair your furnace.
If you discover your Amana furnace is turned on but not heating, there could be several causes. The most common reason why it may not be heating is the air filters in your furnace and around vents are not clean. If you notice a lot of dirt or debris on your filters, your furnace might be working normally, but the filters are not allowing hot air to circulate.
To fix this problem (Read also: Amana Furnace Problems: Fix it Here! ), clean the air filters in your furnace and vents regularly. You should replace your filters every three to four months, depending on how often you use your furnace.
Another reason your Amana furnace is not heating is that the circuit breaker detected a problem. When the circuit breaker trips, your furnace system will immediately shut down and stop producing heat because it is not receiving power. To fix this problem, try resetting your circuit breaker marked “furnace” in your fuse box.
Cycle on and Off Regularly
If your Amana furnace constantly turns on and off, there is a problem with the system’s flame sensor. A flame sensor regulates the gas or electricity in a furnace, ensuring that heat is released only when the system is on. If your flame sensor is faulty, the furnace burner will cycle on and off, and it can cause safety issues.
To ensure that your furnace stays on, clean the flame sensor regularly. Over time, a flame sensor can gather dust, debris, and particles. Your or a technician should clean the flame sensor every six months. If the furnace does not work after cleaning, replace the part.
You should also check your furnace’s thermostat and ensure it is calibrated correctly. If the thermostat is not working, it can cause your furnace to cycle on and off. To fix this problem, replace the batteries in your thermostat. If it continues to malfunction, an HVAC technician should inspect the wiring from the furnace to the thermostat.
Not Blowing Hot Air
The most common cause for Amana furnaces not blowing hot air is a problem with your air filters. After installing air filters, they will collect dirt and debris and prevent them from circulating in your home. Over time, these particles will build up and reduce airflow. If you have not cleaned or replaced your filters regularly, they could be blocking hot air from blowing.
To ensure that hot air blows, check your Amana furnace’s filters. Depending on your model, there could be an in-unit filter. If you have recently replaced the filter, remove it and vacuum any debris or dust. You can also rinse the filter with water, but ensure it is completely dried before you place it back in your furnace.
If you have not replaced your filter within the past three months, you should exchange the filter for a new one. Repeat this process with all of the vents in your house. Moving forward, regularly replace your filters every three to four months, depending on how dirty they get.
Blowing Too Much Air
If your Amana furnace blows too much air, it is likely because of a problem with your blower motor. A blower motor is an important part of your HVAC system because it transfers air from the furnace to the vents in your home. Over time, the blower motor will become dirty from debris and air particles. This process is natural, but an unclean blower motor will release too much air.
To fix the problem, perform regular maintenance on the furnace’s blower motor. If the blower motor is dirty, you will need to remove the part and replace it with a new one. If you have experience with performing repairs on HVAC systems, you can do this work yourself, but a technician can also complete the repairs.
Blower Motor Runs Constantly
If your Amana furnace blower motor runs constantly, it could be because of your thermostat settings. If your thermostat fan is set “on,” your Amana furnace (Read also: Amana Thermostat Troubleshooting: What to Do) will constantly blow air through your vents. This setting will also produce high energy bills because your furnace will always be working, even if it is not releasing heat.
To fix this problem, program the fan settings on your thermostat to “auto”. With “auto,” your Amana furnace will regulate itself, producing heat only when needed.
When you see water leaking from your Amana furnace, there is a problem with its drainage system. Most furnaces have a drain hose that removes condensation or water that naturally appears while the system is running. If the drain hose becomes dirty or clogged, the condensation will cause water leakage.
To check this problem, turn your Amana furnace off. Locate the drain hose and if you notice a clog, clean it out. If the drain hose is leaking or has not been replaced in several years, you should exchange the part for a new one.
For Amana furnace water leakage, you should also inspect the condensate pump. Like the drain hose, over time, the pump can become clogged or dirty. When the pump becomes clogged, excess water or moisture will leak out of your furnace. If you are experiencing problems with your condensate pump, you should have the part replaced by an HVAC technician. Pumps can last two to six years, depending on the brand.
If your Amana furnace is not turning on or heating, there could be problems with your circuit breaker. When this happens, your circuit breaker will trip, causing your furnace to shut down. Circuit breaker tripping is caused by a variety of reasons. If there is bad weather, your local power grid is malfunctioning, or a sudden surge in electrical use in your house or neighborhood, it can cause your circuit breaker to trip.
If your Amana furnace suddenly stops working, find your circuit breaker or fuse box and reset it by flipping the switch. Your system should produce heat again within minutes.
If the furnace does not turn on again after resetting the circuit breaker, you may need to replace your circuit breaker. Your house may have an electrical problem, and you will need to call a specialist.

Here are the most frequently asked questions about troubleshooting the Amana furnace.
To replace your Amana furnace flame sensor, match the part with your existing brand and model. A local distributor or supplier will match the exact flame sensor if you have your furnace’s serial number.
To begin the installation, shut the power off of your furnace. Disconnect the wire from the flame sensor and remove the flame sensor. Place the new flame sensor in the same location, screw it in, and reconnect the wire. To test whether the new flame sensor works, turn your furnace on and let it heat up. You should hear the flame sensor ignite and remain on.
Clean your furnace flame sensor at least once a year. To clean the flame sensor, turn your HVAC system off. Remove the flame sensor and refer to the furnace’s manual to determine how the product should be cleaned. Most technicians recommend using a steel wool cloth
Every Amana furnace has a reset button. Most reset buttons are located next to the blower motor inside the access panel. Remove the access panel and look inside the stove to find the button. You will see a button that is red or yellow. Check your Amana manual for your furnace model’s specific location of the reset button.
To reset your furnace, hold the button down for at least 10 seconds. Your furnace will begin to reset after you release the button. After pressing the button, you may have an electrical problem in your house or building if the furnace is not reset within several minutes.
There are several reasons why your Amana furnace is not heating. A common cause is the air filters in your furnace and vents are dirty and clogged. Clogged filters reduce airflow from the furnace, causing the system not to heat. Replace your air filters every three to four months to ensure proper air circulation.
You should also check your circuit breaker if your furnace is not heating. If you have blown a fuse or your circuit breaker tripped, it will cause your furnace to shut down. By resetting your circuit breaker, the furnace will turn back on and begin to heat.
When your Amana furnace turns off and on regularly, there is a problem with its flame sensor or thermostat. Ensure that your flame sensor is cleaned so that dust and debris do not clog the part and that heat can be released.
You should also make sure the thermostat is correctly calibrated and functioning so that the furnace releases heat at the correct temperature and timing. If the system is cycling on and off, replace your thermostat’s batteries. If you still experience problems, a technician will need to replace the flame sensor or rewire your thermostat.
