Amana heater not working. If you’re looking for a guide on how to troubleshoot your Amana furnace heater, stop looking and keep reading.
We explain the most common issues you will face with your Amana furnace in our complete troubleshooting guide.
It also covers a handful of basics that are necessary to be aware of when your heater stops providing needed warmth.
Amana heater not working
This guide will offer tips and solutions to remedy the problems you may have with your Amana appliance that would not be heating.
Incoming Power issue
If there is no power to the furnace, check the furnace circuit breaker or fuse.
If the circuit breaker or fuse is damaged, contact an authorized technician from your local utility company to fix it.
Check Gas Supply
Inspect the gas turn, a shock to verify that it’s an on the state. If the furnace is fuelled by propane, you must ensure the natural gas crate is full.
Dirty Flame Sensor
By monitoring the flame sensor, the burner can tell if there is a flame. If the flame sensor detects a flame, it sends an electronic signal to the heating control board to activate the gas valve turning on and providing fuel.
However, if there’s no spark in the furnace’s burner, sometimes that means that the dome needs cleaning.
The fuel buildup in combination with dust from inside the flame sensor may prevent the sensor from detecting a flame.
So it can falsely cause a system safety failure shutting off voltage to turn off gas heating mid-cycle and quickly jeopardize your home environment but only temporarily.
Simply clean out the particles from inside of your flame sensor with an abrasive pad like sandpaper not too hard though! And if it still doesn’t work after cleaning then you need to get an upgraded part replaced ASAP.
The igniter heats up and glows orange so that it is hot enough to light the gas burner in your furnace. If the igniter isn’t working or cracks, your furnace won’t work and you’ll end up freezing during the cold nights.
To determine whether there’s a problem with the igniter, remove it from your furnace and inspect it for cracks or damage.
Test continuity with a multimeter if no damage is found. If the igniter doesn’t have continuity, replace it with a new one made by the same company that made your original one.
Faulty Draft Inducer Motor
The draft inducer motor pulls air from outside, passes it through the heat exchanger, and releases it out of the exhaust pipe.
By sensing changes in pressure as a result of this action, the pressure switch knows that sufficient air is flowing through the furnace.
In the case of a defective draft inducer, this pressure switch might not be able to close, leading users to believe there isn’t enough airflow.
The furnace’s control board detects this and eventually, the furnace shuts down after a few minutes if the ignition of fuel is stalled.
Failure of ignition
The control board is an essential device that regulates the power supply to all of a furnace’s components.
A failed control board might not send voltage to the ignition system, which would prevent the furnace from heating up. Poor wiring can also affect voltage and hence lead to failure of ignition.
Defective Flame Rollout Limit Switch
Do not attempt to inspect, service, or repair the flame rollout switch yourself. This can be dangerous as they contain a gas valve which when triggered releases gas into the air.
You should immediately turn off your furnace and contact a licensed technician if you notice that the flame rollout switch has been tripped.
A properly functioning flame rollout switch will depressurize the system and lock itself out of the ignition circuit enabling it to signal that your burner system is in need of inspection by signaling intent with its amber color.
A thermostat contact has failed
If your thermostat isn’t working, then it’s probably more than just a simple repair. More than likely you now have to consider replacing the thermostat.
This can be done so much quicker and more efficiently if you know what you’re doing, which we will show you how to do right now.
We asked Lyle Wells of Chadaire Heating & Cooling in Norwell Massachusetts, to give us some tips on diagnosing his most common HVAC issues.
He told us: “To check if it’s the thermostat or if there is something wrong with the furnace itself –
plug a fan into it for about five minutes and see if that changes anything wait about ten minutes after that and see where the temperature is then.
Problem with Pressure Switch
In the case of air pressure switches, if they are defective or are installed improperly, they can affect how a furnace ignites. Air pressure switches close when there’s enough airflow present.
If the switch is defective or improperly installed, it might not stay closed when adequate airflow is present and could cause a malfunction.
GFCI outlets: these also require some specific knowledge in order to determine if it needs to be repaired or replaced. The most effective way of testing for an open circuit lies in using a multimeter.
