Electronic damper won't close after heat is turned off, closes and open when...

my issue began around Thanksgiving and it was tied to a Nest thermostat running on my single pipe steam (Weil_Mclain EPG Boiler). Long and short of it the spark module was diagnosed as faulty not the thermostat or anything else and I replaced that. I do have a bit of an issue because I noticed that my automatic damper was not closing when the heat call was tuned off. It does close and open when heat call is generated but shuts off in the open position. It is a RVGP-PC-7BKF-CP I saw that they had a recall on them but not in my model number. A H&C contractor gave me a quote of 400 to fix it, wondering if it is a part or cable that needs to be replaced because it does work, thanks for your time.

You don't have the service switch in the " hold open " position, do you?
