Amp-research power steps only works sometimes

AMP Research Power Steps may only work sometimes due to several possible reasons:

1. Temperature Sensitivity – Cold temperatures can affect the step’s ability to retract fully, causing it to stop before reaching the closed position.
2. Motor or Control Unit Issues – The motor or the "brain" unit may be failing after years of use, leading to intermittent operation.
3. Electrical Problems – Issues with ground wires or electrical connections can cause inconsistent performance.
4. Mechanical Play in Linkage – If there is excessive play in the step linkage, it may not fully extend or retract properly.
5. Installation or Wear Over Time – If the motor or linkage was not installed correctly or has experienced wear over time, it could lead to operational issues.

Cleaning electrical connections, checking for physical obstructions, and inspecting the motor and control unit for heat or damage may help diagnose and fix the problem.
