We had a person on here not to long ago with the 6 dashes. When he posted photos of the circuit board one leg of the heater was burnt. Think he had some other issues as well and ended up getting a new board...but were not there yet.
Please post photos of the circuit board and the schematic on the inside cover of the pack.
Several things. Post some pics of the equipment area and circuit board so we can see what you have in there.
Is it just installed or been running for a while?
