Expected Operation
The fault is displayed when too much or too little current is detected on the inducer circuit.
Cause
1. Power outage.
2. Bad wiring to the inducer.
3. Bad inducer.
4. Bad furnace control.
Solution
1. Reset power to unit and clear fault.
2. Check wiring and connections between IFC and Inducer. Correct/replace as necessary.
3. Replace inducer
