GTWP1800DWW GE Washer Mode Shifter Energizing

[Mike Reece]

Model Number

GTWP1800D

I have a GE washer, model GTWP1800DWW.

products.geappliances.com/appliance/gea-specs/GTWP1800DWW

The mode shifter coil was bad in it, so I opened it up and replaced the thermal fuse inside.

I cleared the error code for the mode shifter (4 flashes) on the washer.

Now when I plug the washer in, I can hear the mode shifter clicking right away, meaning it is being energized, and it will stay on. It does it with the washer not running (knob pushed in, lid raised). I waited at least 30 seconds and it did not turn off. Is this normal?

Is the washer doing some kind of self test or is the computer board bad on it causing it to energize the mode shifter when not supposed to?

I am afraid it will burn up the coil again.

Thanks.

Hi Mike,

Your missing a digit between the D and the W.

Here's the results I get:
GTWP1800D0WW
GTWP1800D1WW
GTWP1800D2WW

You can't change the thermal fuse inside the shifter, you have to replace the entire shifter if its bad.

Here's the Mode Shifter assembly for your model you can order(Video Included):
GE WH38X10019 Shaft & Tube Asm


4 flashes - Mode shifter circuit failed. If this error code comes up the motor will still operate but if the mode shifter circuit has failed the washer will not agitate properly. To check the mode shifter, first start the washer. Then when the washer starts agitating, look at the tub from the outside. If the whole inside tub is turning back and forth while in agitate, the mode shifter is bad. If the mode shifter is not bad then clear the code as described below and if the code reoccurs replace the motor.

Let's make sure the shifter is bad first.

1. Disconnect power from the washer.

2. Remove the front off the washer.

3. Disconnect the shifter coil from the motor. It will be the only plug with only two terminals.

4. Then test for continuity across the two wires. You should get around 98 ohms, the important thing is if it is open or not. If it is open replace the shaft and tube and if it is around 98 ohms replace the motor.

Here's the motor for your model you can order if needed:
WH20X10093 Motor and Inverter Asm

Hi, Jake.

That is the model number on the receipt. I could not find the tag on the machine.

The coil was open circuit as tested with an ohmmeter. The problem was the thermal fuse inside which I have replaced. Now the coil operates properly.

My question is, is it normal for the mode shifter to click the moment you plug the washer into the wall, even with the lid open and the start/stop knob pushed in? I did not have this washer prior to it being broken, so I don't know if this is normal behaviour or not. My guess is this is not normal.

Thanks.

What's the part number of the thermal fuse? Post a picture of it too please, because I have no clue what you mean.

No, that's not normal.
