GE Dryer Error Code Moisture Sensor

This fault means the GE dryer control board has detected a short circuit condition across the moisture sensor rods inside the drum. The sensor rods are supposed to measure the dampness of your clothes, but a short reading prevents that from working correctly. As a result, the dryer switches to timed drying for all cycles until the underlying problem is fixed. The most common causes are wiring faults between the sensor and the inverter board or buildup on the sensor rods.

The dryer will continue to operate using timed drying cycles, so it is generally safe to use in the short term. However, without working moisture sensing, the dryer cannot stop automatically when clothes reach the correct dryness level. This can lead to over-drying, which increases energy use and can cause excess wear on fabrics. It is best to address the fault as soon as practical.

Repair costs depend on the root cause. Cleaning the sensor rods costs nothing beyond a small amount of rubbing alcohol. If wiring repairs are needed, parts are typically inexpensive, though a technician's labor may add to the cost. A replacement moisture sensor assembly generally runs in the range of $15 to $50 for parts. If the inverter board is at fault, board replacements tend to cost significantly more, often in the range of $100 to $250 or higher for parts alone.

Many cases of this fault can be addressed without professional help. Start by cleaning the sensor rods inside the drum with rubbing alcohol to remove any lint or fabric softener residue. Next, inspect the wiring harness running from the sensor rods to the inverter board for pinched or damaged wires. If cleaning and wiring repairs do not resolve the fault, the sensor assembly or inverter board may need replacement, which requires more advanced disassembly.

A simple power reset is unlikely to permanently clear this fault because the control board detects the short condition based on live sensor readings each time the dryer operates. If the underlying short in the wiring or sensor rods is still present, the fault condition will return. The fault will only clear reliably once the shorted wiring or faulty sensor component has been repaired or replaced.
