Air Compressor: Open Amp Sensor error in GD compressor

Tue, 31 Mar 2026 20:45:10 -0700

Hi

I am working on Gardner Denver Compressor model Electra Saver.
I recently came across an error message Shutdown 'Open Amp Sensor'

This error message popped up within few minutes upon turning on. There is a light on the Compressor motor as seen in above pic, don't know what it means. The motor doesn't get hot.

After pressing Reset & then Constant run, the compressor runs, in most of the cases - all day. But sometimes it stops after running for few hours with above error message.

I tried to look thru the manual but couldn't find above Error message.
Any thoughts what this error is for & how to fix it?

Thanks

My compressor sat in garage for 3 years when I was sick.

If I stay carb cleaner in carb it barely starts and runs for 30s- 1 min. I changed gas in tank and released comp air. Looks like new. Won’t keep running!

Thanks Tom

My compressor won’t build air. I think it’s leaking where the gauges and the pressure regulator connect to the compressor itself. What tool do I need to take the housing apart?

MiTM Air Compressors AM1HE0205HD 2014: Why does my compressor keep triping reset button

Wed, 05 Nov 2025 10:23:25 -0700

Compressor starts up and blows reset button after building about 20 to 40 pounds of pressure, if I flip the on off switch a couple of times it will let me reset the button , then it runs again and does the same thing, it will keep building up pressure to 120psi.

MiTM Air Compressors AM1HE0205HD 2014: Tough to get going. Blows fuse a couple seconds after turning on

Tue, 04 Nov 2025 10:22:04 -0700

Takes multiple ( 15-20) tries to fully Start and build pressure. With tank at 0 psi flip switch to run and it starts turning over slowly then pops the fuse. Wait for fuse to reset and turn on and same thing slowly turns over then blows fuse. This continues over and over till it warms up???? And finally stays on and builds pressure. What do you think it could be? Capacitors??? Head gasket?? Any suggestions would be appreciated. After it gets going it runs and restarts fine

Craftsman Air Compressor 9191672 2016: Compressor motor restart problem

Wed, 22 Oct 2025 17:51:54 -0700

Craftsman 5 HP air compressor, model 919.167200

Compressor runs ok and switches off when set point is reached. Motor trips breaker when attempting a restart at lower pressure point. Evaluated check valve, unloader valve, and pressure switch, and all are functioning properly. Both the run and start caps are fine. Since the motor starts with no tank pressure the centrifugal switch for the caps appears to be working.

Any other possible issues to consider?
