My Amana Home Furnace Is Not Blowing Heat

Burner Problems

• Amana burners are designed to channel natural gas and ignite it. If you are not receiving hot air, the burner in your furnace might have stopped working correctly while the rest of the system still operates. In this case, the burner might have become clogged and will need to be cleaned. Your sensors or thermostat might also have malfunctioned, leading to a permanently low temperature setting.

Vent Problems

• Gas burners need fresh air to ignite a steady supply of natural gas. Your Amana furnace should have an air supply vent that is attached to an outer wall or roof. These vents can sometimes become blocked over time, which in turn leads to to a lack of air and poor ignition. Clearing the vents of dust, debris or snow might help solve the problem.

Ignitor Problems

• Burners depend on an ignition system; in Amana furnaces, an electrical ignition system creates a spark to ignite the natural gas. If the system is misaligned, it will not be able to ignite the gas properly, and the burner will not turn on. Your ignitor may need to be cleaned, adjusted or replaced entirely, based on the severity of the problem. Your Amana manual should give instructions on how to care for the ignitor.

Fan Problems

• If your furnace is not blowing heat but is producing heat properly, the problem is your fan system. The blower uses a simple motor and fan blades. The motor might have burnt out, the fan belt might have slipped, or the blades might be jammed. Cleaning the fan system and replacing any broken parts can often solve this problem.
