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 isn't working 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 smells like burning, trips the breaker again, or runs on gas and you smell gas.
Symptoms & causes
When an Amana furnace is not working at all, common symptoms include no fan operation, no heat output, and a complete lack of any sounds or indicator lights from the unit. The root causes often stem from a lack of electrical power, a malfunctioning thermostat, or a critical failure of the main control board. Less common but possible causes include a tripped safety switch or a completely failed ignitor preventing any startup sequence.
Tools & parts
A reliable multimeter is essential for checking electrical issues and testing components like the ignitor or control board. A basic screwdriver set will be needed to access the furnace's internal components and panels. Potential replacement parts include an Amana ignitor, an Amana control board, or a new thermostat depending on the cause.
Safety first
Before any inspection or repair, always shut off the electrical power to the Amana furnace at both the main circuit breaker and the dedicated service switch located near the unit. Additionally, turn off the gas supply to the furnace using the manual shut-off valve on the gas line. Failure to follow these steps can lead to severe electrical shock, gas leaks, potential explosions, or burns from hot components.
When to call a pro
A professional HVAC technician should be called immediately if you suspect a gas leak, indicated by a distinct sulfur smell, as this poses a serious health and explosion hazard. Any testing pointing to a cracked heat exchanger, which can release deadly carbon monoxide, absolutely requires expert intervention and replacement. Complex control board failures or issues with the gas valve assembly often demand specialized testing tools and training that only a certified technician possesses.
Questions people ask
Why is my Amana furnace completely dead?
The most common reason for a completely dead Amana furnace is a lack of electrical power. Check the circuit breaker for the furnace in your home's electrical panel and ensure the service switch near the unit is in the 'ON' position.
How do I check if my Amana thermostat is working?
First, replace the batteries in your thermostat if it's a digital model, as low power can cause it to malfunction. Then, set the thermostat to 'HEAT' and raise the temperature significantly above the current room temperature to demand heat from the furnace.
What if I smell gas near my Amana furnace?
If you smell gas, immediately shut off the gas supply to the furnace using the manual valve and evacuate your home. Do not attempt to troubleshoot or restart the furnace; contact your gas company and a professional HVAC technician from a licensed Amana dealer immediately.
