GE Washer Error Code 4 blinks

Four blinks on a GE washer indicate a mode shifter error. The LED blinks 4 times at a 1/4-second on/off rate during a 6-second period to signal this fault. The mode shifter is the component that transitions the washer between agitation and spin cycles. Notably, the motor continues to operate while this error is active, but the machine may not spin correctly.

The washer's motor does continue running during this fault, so the machine is not immediately dangerous to operate. However, without reliable mode shifting, clothes may not spin out properly, and continued use can accelerate wear on drivetrain components. It is best to diagnose and resolve the fault before running additional cycles.

Resetting the washer by unplugging it for a few minutes may temporarily clear the error display, but the fault will return if the underlying issue with the mode shifter or its wiring is not corrected. A reset is useful for confirming whether the problem is intermittent, but it is not a fix. Proper diagnosis of the coil resistance and C7 connector is needed to resolve the error permanently.

A knowledgeable DIYer can start by inspecting and reseating the C7 connector, which requires no special tools and no parts. If the connector looks clean and secure, the next step is measuring the mode shifter coil resistance with a multimeter; a correct reading is approximately 98 ohms at 77 degrees Fahrenheit. Replacing the mode shifter or wiring harness is a moderate-difficulty repair that requires some disassembly of the machine.

If the fix is simply reseating or cleaning the C7 connector, there may be no parts cost at all. A replacement mode shifter assembly typically costs in the range of $40 to $120 for the part. If professional labor is needed, total repair costs including diagnosis and installation generally range from $150 to $300 depending on your location and the service provider.
