Why Has My Amana Furnace Shut Off?
Posted On: November 27, 2023
If your furnace has shut off unexpectedly, there could be several reasons behind it.
Here are some common issues that might cause a furnace to shut off, and it's important to note that for safety reasons, it's recommended to consult a professional HVAC technician to diagnose and address these problems.
Here are some potential reasons for your furnace shutting off:
Thermostat Issues: Incorrect thermostat settings or a malfunctioning thermostat could be causing the furnace to shut off.
Check the thermostat settings to ensure they are configured correctly, and replace the batteries if applicable.
Clogged Air Filters: Dirty or clogged air filters can restrict airflow, causing the furnace to overheat and shut off as a safety measure.
Regularly check and replace the air filters to ensure proper airflow.
Flame Sensor Issues: The flame sensor is a safety device that detects the presence of a flame.
If it's dirty or malfunctioning, the furnace may shut off.
Cleaning or replacing the flame sensor can resolve this issue.
Limit Switch Tripped: Furnaces have a limit switch that shuts off the furnace if it detects overheating.
This can happen due to restricted airflow, a malfunctioning blower motor, or other issues.
A professional technician can inspect and address these issues.
Gas Supply Issues: Check to ensure that there is a steady supply of natural gas or propane to the furnace.
If there are issues with the gas supply, the furnace may shut off.
Pilot Light or Ignition Problems: If your furnace has a pilot light, ensure that it is lit.
For newer models with electronic ignition, problems with the ignition system can cause the furnace to shut off.
Faulty Blower Motor: A malfunctioning blower motor may prevent the proper circulation of air, leading to overheating and automatic shutdown.
A technician can inspect and repair the blower motor if necessary.
Issues with the Control Board: The control board is a critical component that manages the furnace's operation.
If there are issues with the control board, it can lead to unexpected shutdowns.
Professional diagnosis and replacement may be required.
Pressure Switch Problems: Modern furnaces often have a pressure switch that ensures proper ventilation.
If there are issues with the venting system, the pressure switch may be triggered, causing the furnace to shut off.
Safety Features Activated: Furnaces have safety features that automatically shut down the system in case of overheating, gas leaks, or other potentially dangerous conditions.
Because furnaces involve gas and electrical components, it's crucial to prioritize safety and consult with a qualified HVAC technician for a thorough inspection and proper resolution of the issue.
Regular professional maintenance is also recommended to prevent unexpected shutdowns and ensure the efficient operation of your furnace.

I had them replace my furnace last year. When it came time for the air conditioner this year, I did not hesitate to call Twintech again. I will also have them perform regular maintenance on them.

We required a new HVAC replacement after running the old
system for 18 years.

covered all the necessary items.
Installation was fast and very tidy. Everything works as
it should. Our thanks to Greg, Mitch and others for their
excellent work. Recommend this family owned business to
anyone else, considering HVAC or other work.

I needed a new furnace and A/C to replace my 21 yr. old units, and went to the internet to view potential companies in May, I received 3 quotes,
and chose Twintech based on their salesman Dave who was very detailed and covered off everything on what Twintech was all about,
an extremely dedicated company with so many years of experience, and after reading the on line reviews I was sold on Twintech, who did not disappoint as the installation team were top notch with Greg leading,
I would highly recommend this company without any doubts, in my books they are first class all the way. Our new Amana furnace and A/C are working perfectly !

This review is late coming so my apologies to the amazing Twin Tech team! I contacted Dave at Twin Tech for a quote this past Feb (as I was collecting a few) and his recommendation was excellent. From the first meeting with Dave to the team installing the new furnace, not once did i feel uncomfortable . The team were extremely professional yet personable and clean and tidy. Decent companies still exist!
The new furnace just purrs and its just amazing the difference it has made!
(PS my sibling ended up getting a furnace from them as well)
