Dont mean to hijack this thread but I have a code 44 and 2U popping up at the same time. The contactor is not welded together and is working as it should in the start up test but still kicks a 44 code. The 2U code shows a current draw from somewhere but again everything looks normal. I have replaced the relay board and checked all fuses..............I am this close to rolling it out to the trash! Can anyone give me a hint as to where I can check next? Thank you very much for your time.
