In the next five minutes
Safe first steps, before the call. Nothing here needs a tool.
If you smell gas, a carbon monoxide alarm sounds, or anyone feels dizzy or sick: don’t touch any switch or plug, leave and get everyone out, then call 911 or the gas company from outside.
No gas smell? Switch the furnace off at the thermostat and at its breaker.
Don’t use it again until it’s checked, and keep people away from it.
Everything else about this problem
Is it an emergency?
Is an Amana furnace that won't start an emergency?
Usually not, but it can be. Because this can be an emergency, leave it off and get it checked; don't reset it or turn it back on. Stop and call a pro if it keeps tripping the breaker, smells like burning, or you smell gas.
Symptoms & causes
When an Amana furnace won't start or turn on, common symptoms include no heat production, the fan not engaging, or the ignitor failing to glow. Root causes often stem from a tripped circuit breaker, a faulty thermostat, or a clogged air filter restricting airflow. Additionally, issues with the ignitor or flame sensor, which are critical for the ignition sequence, can prevent the furnace from firing up.
Tools & parts
For basic troubleshooting, a multimeter is essential for checking electrical continuity and voltage at various components. A screwdriver set will be needed to access panels and secure connections, while a wire brush is useful for cleaning the flame sensor. Specific replacement parts like a new hot surface ignitor and a flame sensor may be needed.
Safety first
Before attempting any repairs, always shut off the electrical power to the Amana furnace at the main circuit breaker to prevent electrical shock. Additionally, turn off the gas supply valve located near the furnace to eliminate the risk of a gas leak or explosion. Never bypass safety switches or operate the furnace if you smell gas, as this indicates a serious and immediate hazard.
When to call a pro
A professional technician is required if the Amana furnace's main control board is suspected to be faulty, as checking and replacing this complex component demands specialized knowledge. Issues involving the gas valve, such as it failing to open or close properly, should also be handled by a certified expert due to the inherent dangers of gas systems. Furthermore, if you suspect a cracked heat exchanger or persistent complex wiring problems, a professional is necessary to ensure safe and correct repair.
Questions people ask
Why is my Amana furnace not igniting?
Common causes for an Amana furnace not igniting include a faulty hot surface ignitor or a dirty flame sensor. These components are crucial for detecting the pilot light or hot surface ignition and allowing the gas valve to open safely.
What should I check if my Amana furnace has no power?
First, check the circuit breaker for the furnace in your home's electrical panel to ensure it hasn't tripped. Also, verify the furnace's service switch, usually a light switch on or near the furnace, is in the 'on' position.
Can a dirty filter prevent an Amana furnace from starting?
Yes, a severely clogged air filter can restrict airflow, causing the furnace to overheat and trip a safety limit switch. This safety mechanism prevents the furnace from operating until the airflow issue is resolved and the furnace cools down.
