Common Amana Furnace Troubleshooting and Repair

Here are all the details about Amana furnace troubleshooting and repair:

Amana furnace not igniting

The Amana furnace often does not ignite due to the poor or no power supply. 

Check your electrical system and try resetting the furnace’s circuit breaker.

Furnace is igniting but not heating 

Usually one or more blockages of dust or any solid object in air filters can stop your furnace from heating. 

Cleaning the filter furnace frequently helps extend the life of your furnace. 

If this doesn’t work, you can also replace the filter yourself by considering the steps below: 

  1. Turn off your Amana Furnace or the thermostat.
  2. Find the filter, commonly located in the air-intake grill area.
  3. Slide the old filter out by considering which side the arrows are facing.
  4. After taking out the old filter, slide the new one. 
  5. Now you are ready to turn on the device.

Irregular cycling happens 

This error often occurs when your Amana Furnace turns on and off without attaininging the adjusted temperature on the thermostat.

Air blowing issues

Air blowing issues in Amana furnace including either excessive hot air blowing or not blowing air.

Amana Furnace Troubleshooting

Water leakage

The Amana furnace shows leakage issues due to the holes and dripp in drain pipes and hose. 

Check and replace pump, drain line, or drain hose to avoid leakage issues. 

The Amana furnace keeps turning on and off frequently

The flame sensor monitors in your Amana Furnace detect the flame presence. If these sensors get damaged or have dirt on them, it can give false positives to the machine and turn on and off the furnace.

Check the sensor for dirt and clean it after completely turning off the furnace. If the sensor is damaged, you need to replace it.

Amana furnace noise

This glitch commonly occurs when the screws are not accurately screwed up, so their loose grip produces noise.  

Usually, the noise is caused by loose screws, shaking the blower wheel. Tighten the screws or replace the blower wheel if it is damaged.

Other errors in furnace that need more attention

Furnace Not Heating

If your furnace is not heating, it might be due to the shorted electrical system that provides power, or the power switch has been blown.

Check if you can reset the circuit breaker. If it is blown, you need to replace it. The other thing you want to check is the ignitor of the furnace. If there are any cracks in the ignitor, it needs to be replaced. Use a multimeter for the continuity test if no cracks are found.

Furnace Blowing Too Much Air

If your furnace is blowing too much air, check the control board. The control board determines the required voltage amount for each part. 

Replace the control board If there is any fault in the relay that controls the blower. If the relay fails, it will keep transferring excessive voltage to the motor.

It is also recommended to check the thermostat with a multimeter for continuity. If any issue is found in the thermostat, replace it.

Frequently Turning On And Off

The flame sensor monitors in your Amana Furnace detect the flame presence. If these sensors get damaged or have dirt on them, it can give false positives to the machine and turn on and off the furnace.

Check the sensor for dirt and clean it after completely turning off the furnace. If the sensor is damaged, you need to replace it.

Amana Furnace Blower Motor Replacement

The blower motor can also be a troublemaker. Here’s how you can replace it.

Turn Off the Device 

Turn off the furnace power, and close the gas valve before starting the replacement. 

Remove the Assembly

Remove the blower cover panel, and unscrew the mounted screws. Note how the wires are connected, as you will need to connect them later. Unplug the motor wire. Now slide out the blower assembly.

Remove The Old Blower Motor

If your blower motor has a capacitor, unplug the wires and remove them. Disconnect the motor from the assembly by unscrewing the mounted screws.

Replacing The Blower Motor

Place the new motor in the assembly and screw it. Plug the capacitor back, if there is any. Slide in the blower assembly and connect all the wires like before. Place the cover panel back to its black and ensure it is properly shut. 

Now turn on your Amana furnace. It should be working fine now.

Amana Furnace Pressure Switch Stuck On

Amana furnaces have a pressure switch built in them as a safety feature. Its function is to monitor whether there is any venting obstruction. There could be some reasons if your furnace pressure switch is stuck on. Here is how to troubleshoot it

Venting Issue

A blocked flue pipe makes combustion gasses elimination hard. Leafs, dirt, debris, dust, and snow can get stuck easily in the flue pipe of your furnace. 

Check if there is anything stuck in the flue pipe, and you can clean it easily. After cleaning it, the pressure switch will not get stuck again

Broken Switch

If your furnace pressure switch is stuck on, it might be due to a broken or malfunctioning switch. Test the switch with a multimeter, and if it is faulty, replace it

Disconnected Hose

A disconnected pressure switch hose can be the reason your furnace pressure switch is stuck on. Check if the hose is connected correctly, which can be found above the gas burners.

Amana Furnace 6 Flashes

If your Amana Furnaces is flashing six lights, it can be due to a faulty flame sensor. Check if there is any dirt on the flame sensors. If there is any dirt, clean them after switching off your furnace. 

If the flashes persist, try resetting the furnace by restarting it. If It keeps flashing, replace the flame sensors.

Amana Furnace Light and Error Codes

Amana Furnaces have built-in safety features that can communicate the error code. It’s a handy feature that can help the user know what is causing the issue in the furnace. 

Red light Blinking

If the red light is constantly blinking, it means there is line voltage polarity or an issue in the wiring 

Flashing 1 Time

If there is one flash, the issue could be related to blockage or interruption in gas supply, wiring, or flame rot not sensing flame. The solution is to find out the gas interruption and reset it by adjusting it to 20 seconds. The furnace will reset automatically once it is raised back.

Flashing 2 Times

2 Flashes indicate pressure switch shortage, interruption in vent, or the draft inducer might not be working. To resolve it, replace the draft inducer blower pressure switch or check for vent interruptions, such as dirt, debris, etc.

Flashing 3 Times

3 Flashes mean the issue is related to the pressure switch. Check if the switch is broken or not. Check if the switch hose is connected correctly.

Flashing 4 Times

4 Flashes refer to a blockage in the air filter. It can also mean that the drain tubes might be obstructed by dirt or moisture.

Flashing 5 Times

5 Flashes mean that the flame sensor is sensing heat without calling heat. It might be due to the valve closing slowly.

Flashing 6 Times

6 Flashes mean the flame sensor might be faulty or have some dirt on it.
