Severity
Critical
Type
digital display
Estimated repair cost: $200 — $500 (parts + labor)
Warning: This error indicates a potential problem with the gas valve relay, which could lead to a dangerous gas leak or explosion. Shut down the furnace immediately and call for professional service.

How to Fix Amana Code 6R

  1. Step 1: Immediately turn off the furnace at the breaker to stop gas flow.
  2. Step 2: Ensure you and your family evacuate the house.
  3. Step 3: Contact a qualified HVAC technician or your gas company for immediate inspection and repair.

How to Reset Amana Code 6R

  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 6R Mean?

The '6R' error code on your Amana furnace indicates a problem with the gas valve relay. This relay is an electrical switch that controls the flow of gas to the burners. When the furnace control board calls for heat, it energizes the relay, which opens the gas valve. If the relay malfunctions, it can prevent the gas valve from opening or, more dangerously, cause it to open at the wrong time or stay open when it shouldn't. This can lead to a buildup of unburned gas, creating a significant safety hazard. Because this involves gas flow, it's important to address this issue immediately to prevent potential fire or explosion.

Common Causes

  • Faulty gas valve relay on the control board.
  • Wiring issues between the control board and the gas valve.
  • Defective gas valve itself not responding to the relay.
  • Failed control board not sending the correct signal to the relay.

Diagnostic Steps

If... Check Expected
Furnace displays 6R error Measure voltage at the gas valve terminals when the furnace should be firing. 24VAC
No voltage at gas valve with 24VAC at the gas valve relay on the board Check wiring continuity between the control board and the gas valve. Continuity present
Wiring is good, but gas valve doesn't open with 24VAC applied Measure the resistance of the gas valve solenoid. Typically between 20-70 ohms (refer to manufacturer's specs)
Gas valve solenoid resistance is out of range Inspect the gas valve for physical damage or blockage. Valve is free of obstructions and damage
