Amana furnace is not turning on
Most furnaces have a power switch nearby that looks like a regular light switch. Make sure someone hasn’t accidentally turned it off. Additionally, check your electrical box to ensure you don’t have a tripped circuit breaker. If you do, reset it.
Check your thermostat. Is it working properly? It may not be communicating to the furnace. If yours takes batteries, change them. Dust inside and around the thermostat. Check that the screws and wires aren’t loose.
Set the thermostat to “heat” and “on.” Raise the temperature to its max setting. Wait a few minutes and feel if warm air is coming from your registers. If this works, lower the temperature to your ideal setting and switch “on” to “auto.”
Check the air filters in your home and your furnace. You should change these regularly. If they’re too dusty, they block airflow. You can buy new ones on Amazon or at stores like Lowe’s. Make sure you purchase the correct size and type for your system.
If you have a gas furnace, examine the gas valve. It should look like a knob inside your furnace cabinet. It will likely be labeled “on” and “off.” Ensure it’s in the on position. Check your owner’s manual for help if you can’t find it.
If your gas furnace is more than 20 years old, your pilot light might be out. Follow the instructions in your owner’s manual to re-light it.
Finally, check your burners. If they’re dirty, they may be preventing proper ignition. With the furnace off, unscrew them and clean them with a wire brush. Return them to their place and try to start the furnace again.
Call a pro if these Amana furnace troubleshooting recommendations don’t get your furnace back up and running. They can help find and solve the problem.
Amana furnace is not properly heating
First, check your thermostat. Set it to “heat” and “auto.” If the thermostat says “on,” it will blow air even when it’s not actively heating.
Next, check the air filters in your home and your furnace. You should change these regularly. If they’re dusty, they restrict airflow. Follow our furnace filter replacement guide for help.
Make sure all air vents in your home are clear of obstructions like furniture, drapes, and clutter. Check that the vent louvers are open.
If you can access your ductwork, check for blockages or air leaks. You may be able to see inside by removing the registers and looking in with a flashlight. Remove blockages and seal visible leaks with duct sealant or tape. If you can’t access your ducts, consider hiring a duct cleaning company for service.
If you have a gas furnace, check the gas valve inside your furnace. It’s a knob that likely has “on” and “off” markings. It should be in the “on” position.
If your Amana furnace is more than 20 years old, check that the pilot light is on. If it’s gone out, refer to your owner’s manual for instructions on how to relight it.
Any other potential issues are more complex and require the help of an experienced HVAC expert.
Amana furnace is making unusual noises
If you hear a rattling or clinking noise coming from your furnace, it may be a DIY fix. Open the cabinet and look inside for debris or bolts and screws that have come loose inside. With the power off, remove debris and tighten any loose fasteners.
If you hear a scraping, metal-on-metal sound, you likely have an issue with your blower. Look inside your furnace cabinet for a metal wheel. If you see any visible obstructions around the blower, remove them. Otherwise, you’ll have to call a professional for repair.
Any other noises, like screeching, banging, or popping, signify serious issues. Call an HVAC expert for help.
Amana furnace is irregularly cycling
Check your thermostat. Set it to “heat” and “auto.” Dust in and around your thermostat to ensure its sensors can read the indoor temperature accurately.
Check your air filters. Dusty filters may cause short cycling because of restricted airflow. You should change the filters in your home and in your furnace regularly.
Next, check around your home for air leaks. The Department of Energy has tips on how to do this. If you detect a leak, seal it with weatherstripping.
Check your ductwork for leaks and blockages. You can see into your ductwork partially by removing the registers and looking inside with a flashlight. Remove any visible blockages and seal any leaks you see. Also, consider hiring a duct maintenance company to give your ductwork a thorough checkup.
Make sure nothing is blocking your furnace flue. This is the metal tube that leads from your furnace outside your home (either through a wall or the roof). Check for and remove obstructions like animal nests or snowdrifts.
If these Amana furnace troubleshooting tips don’t fix your issue, call a pro for help. You may have a more complex problem, like a faulty flame sensor or heat exchanger.
