Error Code GAS

Gas supply error — gas not supplied to the dryer

Also displayed as: GAS

How to Fix

1. 1

   Confirm the house gas shutoff valve is fully open.

2. 2

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

3. 3

   Inspect the gas supply line for proper connection at the dryer's 3/8-inch NPT connection.

4. 4

   Check for gas leaks using a non-corrosive leak detection fluid on all pipe connections.

5. 5

   If gas is confirmed flowing but GAS error persists, enter diagnostic mode and check Valve 1 voltage — should be 90 Vdc or higher when igniting.

6. 6

   If valve voltage is present, test gas valve resistance: Valve 1 and Valve 2 each should read 1.5 kΩ–2.5 kΩ; replace valve if out of range.

7. 7

   Check igniter resistance (part 5318EL3001): should be 50–800 Ω.

8. 8

   Check flame detector: open above 370°F, closed below 320°F with resistance less than 1 Ω when closed.

9. 9

   If all components test good and error persists, replace the main PCB.
