Cause Action
1. Are Cold and Hot sensors (thermistors) in the correct position? 1. Check wiring diagram, remove, and reinsert. CAUTION - unplug
ION before any contact with Control Board.
2. On Models produced after September 1 … can you hear
a single initialization beep when ION is first plugged in?
2. If YES, then double check sensor wires and replace sensors
as needed.
If NO, then replace Control Board – programming error or defect
on Control Board (perhaps, shipping damage) is preventing
Control Board from initialization.
Problem: Steady Orange lights (never goes to blinking Orange lights)
IMPORTANT – on software rev level prior to L (Sept. 2007), a hot or cold sensor unplugged (or not completely
connected) will cause this condition. During shipping, the sensor connections can become unstable and may require
careful removal (straight back) and reinsertion onto the Control Board (see wiring diagram). CAUTION – unplug ION
before any contact with Control Board.
