Modern furnaces, such as the Amana Air Command 80, do not have conventional pilot lights that burn continuously. An electronic ignition device controls the furnace ignition from the initial call for heat from your thermostat to main burner ignition. A failure anywhere in the ignition sequence will prevent the furnace from igniting and heating your home. Momentarily turn off the electricity to your furnace after a failed ignition attempt to reset any electronic controls before you try again to light an Amana Air Command 80 Upflow GUI.

Turn off the electricity to your Amana air command furnace at the fuse or circuit breaker panel.
Set your thermostat to the lowest setting.
Turn the knob on the gas valve to "OFF." Do not force or use tools to turn the knob.
Smell for natural gas around the inside of the furnace and the controls area. Also smell by the floor, because some natural gas is heavier than air. If you smell gas, do not attempt to light the appliance. Do not use any electric switches or telephones in your home. Call the gas company from a neighbor's house. If you cannot reach your gas company, call the fire department. If you smell no gas, proceed to the next step.
Turn the knob on the gas valve to "ON."
Turn the electricity back on to your Amana GUI furnace.
Set your thermostat to your desired setting. If your Amana Air Command 80 furnace does not automatically start, call your service technician or gas company.
