Previous service company told owners to just recycle power, but we want to get to the real source. Unit just completely shuts down, and has the potential of trapping passengers. Hitting reset on 188E Board brings unit back online. Sometimes will run for 2weeks, sometimes only 2hours. Really appreciate any help.

It is only a 2stop, but seems to throw the 1087 Fault on the downward trip, as soon as it lands on 1. 1087 - Valve Contact OFF Error Possible causes: Stuck Valve Pilot Relay Stuck Motor Contactor Auxiliary Contact Defective MCD Input Bad CPU Card Magnets at Top are Bad or in the Wrong Sequence Help!
