Issue with Kwikee Steps not extending 351 DS

[jvish33]

For some reason out of the blue Steps to my 351 DS stopped extending.
This happen when I turned on the engine. They came up... But now when I open the door they will not come out. Checked fuses in line with battery and in small black box above the Deep cycle Batts. All were good. Am I missing another fuse? Lockout button next to step lights and I do understand how that works.
Steps I took before it happen.
I shut the gen set off. door was open...
turned ignition key (steps came up)
Closed the door
Opened the door and steps never came back out and have not since.

Any suggestions?

Does the lockout button light? Make sure that the door magnet is still there and makes pretty close contact with the coil at the bottom of the door. Check the connectors between the motor ( 2 pole) and the 4 pole connector between the RV and the step controller. Both are under the steps and easily visible.

Thanks Scott..
Yes the lock out lights.. Pulled and reconnected 4 way connector and 2 way to motor. Magnets are still there and seem to be fine. this is a 3 step replacement for the lipert disaster bolt issue. Had them for 1 year...!!!
