GE Dryer Error Code 12

Error code 12 on a GE dryer signals a Redundant Flood Condition, meaning the dryer's backup processor has received an extended period of elevated pressure readings from the pressure sensing system. The code indicates the sensor output voltage is not matching expected conditions inside the drum basket. The dryer halts operation as a safety precaution until the underlying issue is resolved.

A reset may temporarily clear the code, but if the underlying cause such as a blocked pressure tube, faulty valve, or incorrect sensor voltage is not corrected, the error will return. It is best to diagnose and fix the root cause before relying on a reset to resume normal operation.

If the issue is only a blocked or water-filled pressure tube, the repair may cost little to nothing beyond your time. If a valve needs replacement, expect to spend roughly $20 to $75 in parts depending on the specific valve. A pressure sensor replacement typically falls in the $30 to $100 range for parts, with additional labor costs if a technician is involved.

Start by checking the pressure tube for any trapped water and clearing it if found. Next, test each valve to confirm it is operating correctly. Then measure the voltage output from the pressure sensor to verify it accurately corresponds to the water level in the basket. If the tube and valves are fine but the sensor voltage is stuck or incorrect, the pressure sensor may need to be replaced.

Yes, this code is generated by a backup safety processor specifically designed to catch flood-related conditions that the primary control may not fully address. The dryer stops itself to prevent potential damage. You should not bypass or ignore this code without identifying and resolving the cause first.
