Type
digital display
Estimated repair cost: $200 — $500 (parts + labor)
Warning: This error indicates the furnace is detecting a flame when it shouldn't be, which could mean a dangerous gas leak or carbon monoxide risk. Shut the furnace down immediately and call for professional service.

How to Fix Amana Code 1R

  1. Step 1: Turn off the furnace immediately at the breaker. This will stop the flow of gas and prevent further issues.
  2. Step 2: Open windows and doors to ventilate your home, in case of gas or carbon monoxide buildup.
  3. Step 3: Evacuate your home and call your local gas company or a qualified HVAC technician right away. Do not attempt to restart the furnace yourself.

How to Reset Amana Code 1R

  1. Turn off the furnace power switch, usually located on or near the unit.
  2. Turn off the circuit breaker for the furnace. Wait 30 seconds.
  3. Restore power at the breaker and flip the furnace switch back on.
  4. Set the thermostat to call for heat. If the error code returns after 2-3 ignition attempts, the fault requires repair.

Resetting clears the code from the display but does not fix the underlying fault. If the code returns after reset, proceed to the diagnostic steps above.

What Does Amana Error Code 1R Mean?

The '1R' error code on your Amana furnace, labeled 'Flame Without Call,' means the furnace's flame sensor is detecting a flame even when there's no active call for heat. In other words, the burner is firing up at the wrong time, or not shutting off when it should. This is a serious issue because it suggests that gas is being supplied to the burner even when the system isn't calling for heat. This can lead to wasted fuel, overheating, and, most importantly, a dangerous buildup of carbon monoxide inside your home. It's important to address this issue immediately to ensure the safety of your home and family. The problem could stem from a faulty gas valve, a problem with the control board, or even a short in the flame sensor circuit.

Common Causes

  • Faulty gas valve leaking gas into the burner chamber
  • Sticking or shorted gas valve relay on the control board
  • Short circuit in the flame sensor wiring or the sensor itself
  • Defective control board sending voltage to the gas valve at the wrong time

Diagnostic Steps

If... Check Expected
Furnace is off, but gas valve is passing gas Measure voltage at the gas valve terminals with no call for heat 0 VAC. Any voltage indicates a faulty control board or wiring.
Gas valve voltage is correct (0 VAC) with no call for heat Check gas valve for mechanical failure Valve should be closed and not passing gas. If passing gas, valve is faulty.
Gas valve is not passing gas, but flame is present Inspect flame sensor wiring for shorts to ground Wiring should be properly insulated with no exposed conductors.
Wiring is good, but error persists Check the flame sensor microamp signal with no call for heat 0 uA. Any reading above 0 indicates a faulty sensor or control board.
