Gibson Dryer steam function not working

If your Gibson dryer steam function is not working, start with the most likely culprit: a failed control board that is not sending power to the water inlet valve or the steam generator. Inspect the board for burn marks or obvious shorts, since the control board is hard to bench-test but often the root cause. If the board is supplying power to the steam generator but you still get no steam, the steam generator itself is likely defective and needs replacement. Less likely causes include a disconnected water supply hose, a clogged or damaged nozzle that prevents mist from reaching the drum, or a bad water inlet valve that fails continuity testing with a multimeter. Whether you’re troubleshooting a dryer steam not working problem on steam fresh or steam sanitize cycles, these checks will narrow the fault quickly. Enter your dryer model number on RepairClinic.com to find the exact Gibson control board, steam generator, water inlet valve, or nozzle replacement part you need, and follow the parts diagrams and instructions to complete the repair.

01 - Gibson Dryer Control Board

If no power is getting to either the dryer's water inlet valve during the steam cycle or the steam generator, then it's likely the dryer's control board is defective and the cause of the steam function problem. The control board cannot be easily tested, but you can try to inspect it for signs of burning or a shorted-out component to help determine if the part should be replaced.

04 - Water supply not connected.

The water supply hose needs to be connected from the home's water supply to the water inlet valve on the dryer. The water line is usually connected to a “Y” connector and shares the same cold-water supply as the washer. Refer to the owner's manual for water hookup instructions.
Common

05 - Gibson Dryer Nozzle

The nozzle, normally located at the rear interior of the dryer, may be damaged or clogged with debris and unable to allow the steam to enter the drum area. Inspect the nozzle or any damage or obstruction and replace if necessary.
Less Common

06 - Gibson Dryer Water Inlet Valve

The dryer's water inlet valve provides the water necessary for the steam function to work. If there is no mist coming from the nozzle when the valve is energized, it's likely the inlet valve is defective. You can use a multimeter to test the valve for electrical continuity. If the valve tests negative for continuity, you'll know the part has failed and will need to be replaced.
Less Common

07 - Water Supply Valves are Closed

The water supply valve needs to be turned on to supply water to the dryer. The water line is usually connected to a “Y” connector and shares the same cold-water supply as the washer. Refer to the owner's manual for water hookup instructions.
