(Updated for 2019)
A complete Amana furnace repair guide, from how to replace your air filter, to troubleshooting and error codes, model numbers and more!
Please note, the following is for informational purposes only. Any servicing you attempt is at your own risk.
Amana is regularly recognized as the maker of some of the most energy-efficient furnaces on the market, with many of their units receiving ENERGY STAR® certification.
This guide will provide you with some answers and potential fixes should your own Amana furnace run into any need for repair.
How to Replace Your Air Filter
An important but often overlooked maintenance task is remembering to change the air filter on your furnace regularly. When your filter is working properly, your furnace is able to function at peak performance.
An efficient filter also lengthens the life of your blower motor, and keeps the compressor coils from getting clogged.
- Open or slide the door panel to get access to your Amana furnace.
- You will usually find the filter near where the cold air enters the unit, either in the cold air return duct or the entrance to the blower chamber (sometimes in both locations).
- Slide out the old air filter and replace it with a new one.
- Make certain that the “air flow” signifiers on the filter are facing the correct direction, towards the blower and away from the cold air.
- Replace the panel or door to your furnace.
Additionally, it’s also important to regularly vacuum vents and check registers to make sure that they aren’t blocked. And it’s never a bad idea to clean inside your furnace, vacuum both in and around the unit’s blower to remove extra dust and debris that may have accumulated.
What’s Wrong With Your Amana Furnace?
Remember to always turn your furnace completely off before opening it up to look around or attempt any fix.
|Is your furnace...||The problem might be your...||What's wrong?||How you can fix it:|
|Not heating?||Circuit Breaker/Fuse||Most likely, either the electrical system providing your furnace’s power has shorted or the power switch has blown.||Try resetting your furnace’s circuit breaker. If it has blown, you will need to replace it.|
|Igniter||The furnace’s igniter might either be cracked or faulty.||Check the part for cracks, if it is then replace the igniter. If it isn’t cracked, use a multimeter to test for continuity.|
|Cycling irregularly?||Thermostat||Your thermostat might be adjusting incorrectly, causing the furnace to cycle on and off too often.||If your thermostat has an adjustable calibration scale, adjust the heat anticipator. If this does not stabilize the unit, you may have to replace the thermostat.|
|Not blowing hot air?||Blower Motor||Your blower motor may have completely burnt out. If this doesn’t seem to be the case, then the connecting belt may have simply broken.||Test to see if power is reaching the motor. If it does, but isn’t running, the motor has likely failed. If the motor runs but air doesn’t move, the connecting belt has probably broken. You’ll have to replace the belt.|
|Blowing too much air?||Control Board||The control board regulates the amount of voltage that reaches each functioning part. If the relay that controls the blower motor has failed, it will continually send voltage to the motor.||Replace the control board.|
|Thermostat||The contact that controls the blower motor on your thermostat may be stuck closed, causing the blower motor to run continuously.||Use a multimeter to check for continuity. If it appears the thermostat is the issue, replace it.|
|Leaking water?||Drain Pipe|
|Starting and then stopping shortly after?||Flame Sensor||Your furnace’s flame sensor monitors the burner, detecting whether a flame is present. If it is either defective or dirty, it will not be able to detect a flame.||If dirty, clean the sensor using a fine abrasive pad. If faulty, replace the flame sensor.|
Amana Furnace Error Codes
|Amana Error Code||What this means||Action required|
|One LED flash that stays on continuously||No signal from the thermostat.||Turn off the unit’s power and check connections.|
|Single LED flash||Furnace lockout due to an excessive number of ignition retries (3).||Locate and correct gas interruption. Reset by lowering it for 20 seconds and then raise it back, furnace will reset itself after one hour.|
|Two LED flashes||Draft inducer is not operating or the pressure switch circuit has closed.||Replace the induced draft blower pressure switch, or repair the short.|
|Three LED flashes||The pressure switch is open.||Pressure switch may need to be replaced.|
|Four LED flashes||Pressure issue. High limit cut-off due to faulty wiring or bad filters.||Replace or clean the air filter; clean drain tubes of moisture or debris; may have an open limit switch that requires a jump, ensure not to run it with the main switch bypassed.|
|Five LED flashes||The unit is sensing a flame without a call for heat.||Might be the result of a slowly closing valve. Turn off the gas until the valve is fixed.|
|Seven LED flashes||Faulty flame sensor.||Flame sensor might be dirty or placed too far from flame. Clean if dirty, replace if defective.|
|Continuous LED flashing||Polarity of volt power is reversed.||Review wiring diagram to correct polarity.|
When Should You Call A Professional?
While you can troubleshoot a number of issues on your own, you may want to contact a trained furnace technician should you be experiencing certain issues with your Amana unit.
If after your troubleshooting your furnace still isn’t producing any heat, is leaking or dripping, or is making strange noises (gurgling, banging, whistling, etc.), there might be some broken internal components within your unit. In this case, you will want to contact a trained technician to service your Amana furnace.
Also, if you notice that your furnace is continuously switching itself off and on, you may want to call a technician. This may be a sign that something is not circulating properly within your furnace, possibly tripping up the sensors.
Who Should You Call?
Once you’ve begun experiencing issues with your Amana furnace, it can be difficult to know who to call.
It’s always a good idea to consult online consumer reviews to initially narrow down your local business options, but it’s important to understand that these can’t be used as de facto resources for making your final decision.
