Need service manual. Getting a dr messsags in display. Unit shuts off after 15 mins. This has been something in the past I haven’t been able to solve due to lack of information/ service info. You would think it’s a drain message but sump is not full of muck. I cleaned condenser myself today, they said after 15 minutes it stops with dr message. Any answers or service info appreciated.
