I recently moved and had to remove the helix probe from my rack during the move - I'm in the new house and I can't seem to get the flex watt heat tape to heat the rack like it used to. The unit has backbeat, the room is at 77 degrees but in order to attain a 89/90 hot side I have to run the helix at 100. I never had to do that in the other house.

What do you all think is the problem - what should I do to adjust it or is this fine

Thanks
