Amana Error Code 5R: Ignition Lockout

⚠️ The furnace has locked out due to repeated failed ignition attempts, which could indicate a gas leak or carbon monoxide risk. Shut down the furnace immediately and call for professional service.

How to Fix Amana Code 5R

  1. Step 1: Turn off the furnace: Locate the furnace power switch (usually on the side of the unit) and turn it to the 'off' position.
  2. Step 2: Check the gas supply: Ensure that the gas shut-off valve near the furnace is fully open. Also, check that other gas appliances in your home are working.
  3. Step 3: Call a qualified HVAC technician: Do not attempt to troubleshoot the furnace yourself, as this could be dangerous. Contact a licensed HVAC professional to diagnose and repair the problem.

What Does Amana Error Code 5R Mean?

The '5R' error code on your Amana furnace indicates an 'Ignition Lockout'. This means the furnace tried several times to light the burners but failed. After multiple failed attempts (typically 3-5), the furnace control board shuts down the gas valve and blower motor as a safety precaution to prevent a dangerous buildup of gas inside the unit and your home. This lockout requires a manual reset in some cases, but more importantly, it signals an underlying problem that needs to be diagnosed and fixed by a qualified technician. Ignoring this error could lead to a hazardous situation.

Common Causes of Amana Code 5R

  • Dirty or faulty flame sensor: The flame sensor doesn't detect the flame, even when one is present, causing the control board to shut off the gas.
  • Blocked or restricted gas supply: A closed gas valve, kinked gas line, or malfunctioning gas regulator can prevent gas from reaching the burners.
  • Failed igniter: The hot surface igniter (HSI) is not getting hot enough to ignite the gas, or it has failed completely.
  • Faulty gas valve: The gas valve is not opening to allow gas flow to the burners.
  • Defective control board: The control board is not sending the correct signals to the igniter or gas valve.
