1. Check B+ supply of actuator
2. Check triggering wire for continuity
3. Replace actuator

Hopefully the tech went through steps 1 & 2 before doing 3.]]> Boxsterra Main ForumWed, 06 Mar 2019 19:23:29 -0500 https://pedrosboard.com/read.php?7,51197,51197#msg-51197 Forever CELhttps://pedrosboard.com/read.php?7,51197,51197#msg-51197 vza Main ForumTue, 05 Mar 2019 18:28:13 -0500
