ERV & HRV Fresh Air Systems User and Installer ManualCarrier E01 fault code

E01 | Supply damper range | STEP 1: Unplug unit, inspect the damper system, remove any undesirable obstacle or dirt (filters and core may
have to be removed to access the damper system). Plug in the unit.
If STEP 1 did not fix the problem, perform STEP 2: Open electrical compartment, check if connector J5 (white)
is well inserted, check for any loose wires.
If STEP 2 did not fix the problem, perform STEP 3: If the damper is not moving at all, unplug J7 (red) from the
electronic assembly, connect the white damper system connector into J7. If the damper moves (but the system
still shows an error), the electronic assembly must be replaced.
Otherwise, replace the damper system.
