Error Code gAS

Gas supply or gas service turned off

Also displayed as: gAS

How to Fix

1. 1

   Confirm that the house gas shutoff valve is fully open.

2. 2

   Confirm that the dryer gas shutoff valve (installed within 6 ft of dryer) is fully open.

3. 3

   Check that gas supply line is connected and not kinked or damaged.

4. 4

   Turn off gas, disconnect supply hose, and verify no blockage in gas inlet.

5. 5

   Perform gas leak check at all connections using a non-corrosive leak detection fluid after restoring gas.

6. 6

   If gas supply is confirmed adequate and dryer still shows gAS, check gas valve coil resistances (Valve 1 and Valve 2: each 1.5 kΩ–2.5 kΩ) and replace gas valve if out of range.

7. 7

   Check igniter resistance (50–800 Ω); replace if open circuit.

8. 8

   Check flame detector (open at 370°F max, close at 320°F, closed resistance less than 1 Ω); replace if faulty.

9. 9

   Check hi-limit thermostat (open at 203±4°F, close at 158±4°F) and safety thermostat (open at 230±4°F, manual reset); replace faulty thermostats.
