Heater stopped blowing - quick troubleshooting tips?
Rennlist fam -
Raining and cold here in DC today. Started her up fine. Blower was working. Changed it from 3 to off. Tried to turn it back on - nothing.
I know it’s well documented - maybe too well. I can’t seem to find a thread to simply troubleshoot the issue. Any pointers or redirects would be kindly appreciated.

On a same subject, mine just started to be super hot and not able to bring the temperature down. This happened couple of days after i took the CCU unit out cleaned and grease the small fan that was making noise. It was great for couple of days and no noisier and super hot. Any suggestion is greatly appreciate it.
Thank you in advance,

Check you rear fan, does it run on low and high speed?

I just removed, cleaned and re-installed the servo control box that controls the heat. Sorry I can't remember which one it was.
Easy fix.
