I can't speak to your specific situation. The best function for this heater is to set the temp on the switch to 104± but don't mix any cold, that just screws it up. I f to haven't already, go to thormotorcoach.com and register at the owner's portal. You'll need your VIN. You always need the last 8 digits to communicate with customer service. In the owner's section you'll see Vehicle Documents. There you can d/l the manuals for all the appliances. You find troubleshooting guides in most. Keep digging and you'll find helpful videos (±). Hopefully you'll come up with some help.

Also use the Seach feature of the forum, someone may have dealt with this before.
Good luck.
