You replaced the handle with a what? Rebuilt? Raymond rebuilt ?
From the frying pan into the fire. Hard to find decent rebuilt's. I change them 3 0r 4 times in a row until you get a decent one.
But is this one bad too? push and pull the handle forward while twisting it sideways. If defective, it will code out. While on the lift pot, pull the handle back and put side force on it, like a driver may do. You may still have a bad handle. Stress it like the drivers do, the failure may occur
