Control board

1. Disconnect the leads and connectors connected to

 

 

 

 

 

 

 

 

assembly

 

the other parts from the control board assembly.

 

 

 

 

 

 

 

 

 

 

1) Leads

 

 

 

 

 

 

 

 

 

 

• 3 leads (black, white, orange) connected to

 

CN603

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

terminal block.

 

CN601

CN600

 

CN701

 

 

 

• Lead connected to compressor :

 

CN500

 

 

 

CN300

 

 

 

 

 

 

 

 

 

 

 

CN700

CN602

 

 

 

Disconnect the connector (3P).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

• Lead connected to reactor :

 

 

 

 

 

 

 

 

 

 

Disconnect the two connectors (2P).

 

 

 

 

 

 

 

 

 

 

2) Connectors (×8)

 

 

 

 

 

 

 

 

 

 

CN300 : Outdoor fan motor (3P: white)*

CN300, CN701, CN600 and

 

 

 

(* : See Note)

 

 

 

CN701 : 4-way valve (2P: yellow)*

CN603 are connectors with

 

 

 

locking mechanisms: as such,

 

 

 

CN600 : TE sensor (2P: white)*

 

 

 

to disconnect them, they must

 

 

 

CN700 : PMV (6P: white)

 

 

 

be pressed in the direction of

 

 

 

CN603 : TS sensor (3P: white)*

the arrow while pulling them

 

 

 

CN601 :TD sensor (3P: white)*

out.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

CN602 : TO sensor (2P: white)

 

 

 

 

 

 

 

 

 

 

CN500 : Pressure SW. (2P:white)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

NOTE

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

These connectors have a disconnect prevention

 

 

 

 

 

 

 

 

 

 

 

mechanism: as such, the lock on their housing

 

 

 

 

 

 

 

 

 

 

 

must be released before they are disconnected.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2. Remove the control board assembly from the P.C.

 

 

 

 

 

 

 

 

 

 

board base. (Remove the heat sink and control

 

 

 

 

 

 

 

 

 

 

board assembly while keeping them screwed

 

 

 

 

 

 

 

 

 

 

together.)

 

 

P.C. board base

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

P.C. board

 

 

 

 

 

 

 

NOTE

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Disengage the four claws of the P.C. board base,

 

 

 

 

 

 

 

 

 

 

 

hold the heat sink, and lift to remove it.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

3. Remove the two fixing screws used to secure the

 

 

 

 

 

 

 

 

 

 

heat sink and control board assembly.

 

 

 

 

 

 

 

 

 

4. Mount the new control board assembly.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

NOTE

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

When mounting the new control board assembly,

 

 

 

 

 

 

 

 

 

 

 

ensure that the P.C. board is inserted properly

 

 

 

 

 

 

 

 

 

 

 

into the P.C. board support groove.
