  The free-piston Stirling engine is not maintaining a working temperature.  

This could arise from blocked filters, blocked air passages, unusually hot 
ambient temperatures (for example >45ºC), or a fan failure. Check air 
passages and clear any blockages for good air circulation. Remove from  
hot environments (car interiors, etc.).

  A component which monitors free-piston Stirling engine performance has 

failed. The free-piston Stirling engine cannot regulate itself. Please return  
for repair.
