The damper system 
does not work 
(ERV100SP unit only)
(

AMBER error code

).

At power up, no RED LED

.

At power up, LED lights RED and 
there is a clicking sound coming 
from electrical compartment, but 
damper does not move

:

• Ice or other things hindering the 
 damper 

movement.

•  J12 unconnected or bad contact.
•  Wrong connection of J8.
• The transformer may be defective 
  (no 24 VAC between J8-1 and J8-2).

•  The damper actuator 
  may be defective.

Damper moves but does not stop 
when supposed to

:

•  Bad connection of J12 connector.
• Damper PCB defective or damper 

motor stripped gear.

•  The main PCB is defective.

•  See point 5.

•  Remove ice or hindering elements.

•  Check J12 connection (both harness side and board side).
•  Check J8 connection.
•  With unit powered and J9 connected, check if there is about 

20-24 VAC between transformer connector J8-1 and J8-2 
(ORANGE wires). If no, change the transformer.

•  Replace the damper system.

•  Check J12 connection (both harness side and board side).
•  Replace the damper system.

•  Replace the main PCB.

A. The supply motor does 

not work, but exhaust 
motor works.

B. The LED flashes RED.

•  The supply motor may be defective.

• The supply motor capacitor or the 

PCB may be defective.

•  The exhaust motor may be defective.

•  The exhaust motor capacitor may be 

defective.

•  Tranformer wire(s) bad connection.

•  The transformer or the PCB may be 

defective.

• Plug supply motor to J5 connector and exhaust motor to 

J4 connector. If the LED flashes RED, the supply motor is 
defective. If exhaust motor works, plug back supply motor 
to J4 connector and exhaust motor to J5 connector, then 
check for supply motor capacitor validity.

• Plug supply motor capacitor to J7 connector and exhaust 

motor capacitor to J6 connector. If the LED flashes RED, the 
supply motor capacitor is defective. If there is no change, 
the PCB is defective.

• Plug exhaust motor to J4 connector and supply motor to 

J5 connector. If supply motor works but exhaust motor does 
not, exhaust motor is defective. If exhaust motor works, plug 
back supply motor to J4 connector and exhaust motor to J5 
connector, then check for exhaust motor capacitor validity.

•  Plug exhaust motor capacitor to J6 connector and exhaust 

motor capacitor to J7 connector. If exhaust motor works 
but supply motor does not, the exhaust motor capacitor is 
defective. If there is no change, check validity of transformer 
or PCB.

• Check J8 and J9 connectors, as well as BLUE and RED 

wire connections from J9.

•  Move JU1 jumper from pins 2 and 3 to pins 1 and 2. Set the 

unit on high speed. If exhaust motor works, the transformer 
is defective. If it still does not, change the PCB.

Unit shows protection 
mode error (different than 
being in protection mode)

•  Wrong selection of defrost cycle.
•  Defective motor or damper.

• Stale air flow choked (unbalanced 

unit, filters or outdoor port clogged, 
etc.).

• Inside temperature too low (around 

64°F).

•  Refer to Section 3.2 or 3.4, according to the unit model.
• Inspect the complete unit, make sure both motors are 

running, make sure the damper system closes and seal 
properly.

• Inspect the complete ducting, clean the filters, stale air 

inside grille, etc., balance the unit).

• Unit is using the inside temperature to defrost itself, so a 

very low room temperature can harm the defrost system of 
the unit.
