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 left a live chat message on their website that my air conditioning was not working. Within 1hr a representative called me to discuss my options.
The next day he came to the house to review my needs and give me a price for a new system. Price quoted was less than I expected and the installation was completed the following day. I found their salesman and the installers very knowledgeable and easy to deal with. All my questions were answered. Everything was properly explained in regards to what unit was needed and why, along with instruction where needed for use.
The installers made sure everything was working properly before they left.

Our furnace was rattling, as soon as we put our air conditioner on this past week. We had researched looking for a company that was Registered with Better Business Bureau, and this company TwinTech, had A+ Rating. Scott, was immediately helpful via text/phone and sent his technician as soon as he was able...Mitchell/technician provided great professional service. Thank you TwinTech.

I contacted various companies when looking to install a new furnace and I found Twintech to be transparent with their communication and approach. They had options to suit my various requirements and the price vs quality was very good. The after installation communication was also very good and they answered all queries I had.
