Alarm sound but heat comes out
Posted: Sat Nov 20, 2010 7:19 pm
I have a Coleman DGAA077BDTA 77,000 BTU heater air conditioner. The Deluxe Blend Air II 7681-8171/b is sounding an alarm. The red light is flashing continuously.
I can switch off the alarm and the heater appears to work fine...BUT I don't know what is wrong.
The warning codes indicates that I have reversed polarity...Duh? Where ? What?
I have turned off all power to the unit. Turned it back on, and the error persists.
Is there an easy fix?
Thanks
Dave
