These instructions describe how to properly replace a
single stage *G6/L1 control board (PN 624631) with a
*G7 control board (PN 624690). These instructions only
apply to *G7 single stage furnaces.
WARNING:
To avoid electric shock, personal injury, or death,
turn off the electric power at the disconnect
or the main service panel before making any
electrical connections.
CAUTION:
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation. Verify
proper operation after servicing.
When replacing the *G6/L1 control board (PN 624631)
with a *G7 control board (PN 624690), install all wires
from the door switch and 24V transformer on the same
pin locations they were removed from. This means the
wire that was attached to the L1 terminal on the 624631
control board will need to be attached to the L1 terminal
on the 624690 board, the wire on the XFMR terminal of
the *G6/L1 board should be placed on the XFMR terminal
of the *G7 board, etc.
When connecting the wires from the thermostat, heat
pump, AC unit, or air handler to the RCYGW terminals
of the *G7 board, install all wires on the same terminals
they were removed from.
SELECT INSTRUCTION
**ATTENTION INSTALLERS**
When connecting the wires from the blower motor, please
note which wire connects to the HEAT and COOL terminals
on the *G7 control board. NOTE: If the motor does not
have an orange wire, do not place any wire on the Medium
Low terminal, this should be left empty.
The 6 pin (P1) and the 9 pin (P2) wire plugs will connect
directly to the 624690 control board, there is no need to
change any wire position.
Place label with flash codes near the wiring diagram on
the furnace door for future reference.
