Heater Control - Trouble Code ?
Hi Guys

Have a 3750FL about a year old & love it - my Dometic Digital heater control just stsrted displaying a code of A9UA instead of the regular FURN when on heating. Seems to be working fine, keeping us toasty here in Wyoming -15F at night +20F during the day.

Anybody know what this code means, nothing in the owners manual.

You may wish to consider removing power to the t'stat for a few secs and then back on...
Good luck....
