Garage Mechanic for Model Number gcg1580L0ss

The compactor stopped working and only hummed when I started the compaction cycle. I replaced the motor and now the unit starts. But the compactor ram only moves about two inches and then stops. I hear the motor click when the ram stops. I reset the ram to the start position and can restart but only after the motor clicks again after a few minutes. When I restart, the ram still only goes 2 inches. I noticed that the drawer trip switch was flashing blue inside, so I think it might be a short in it. So I think I should order a new switch. Given the problem with the travel of the ram, should I also get the directional and limit switches? I can't figure out why the ram won't complete the cycle once started. Thanks.

Hello Garage mechanic. Yes, if it is flashing, you will need to replace the switch as well.

Tim for Model Number GCG1580

When pedal is lifted compactor makes a humming sound but nothing moves. Took apart and replaced a clip on the gear that was off. Worked fine for several days; now doing the same thing. Read several forums with others having same problem. Some said replacing the directional switch solved their problem. In the diagram, it appears there are 2 directional switches (part # 102)? Also the top limit/directional switch (part # 138)... same thing? Is there a way to test the switches? Which switch should I replace and how many of each do I need?

1 Answer

Hello Tim, It sounds like the door tilt switch WC21X20109 is the issue but it is normally caused by the drawer being out of whack. You should check the rollers and tracks to determine if they are contributing to the issue or if the switch is just failing.

Hi. The top switch is a ON/Off switch part # WC21X20129. If the start switch contacts are fused then this will occur. Next to it is a top limit (Directional) switch part # WC21X20249. If it is stuck on (ohms closed) then it will create this action. Thank You.
