Care And Maintenance - Payne PG80ESAA Installation, Start-Up, Operating And Service And Maintenance Instructions

The electrical ground and polarity for 115- -v wiring must be
properly maintained. Refer to Fig. 25 for field wiring information
and to Fig. 48 for furnace wiring information.
NOTE: If the polarity is not correct, the STATUS LED on the
control will flash rapidly and prevent the furnace from heating.
The control system also requires an earth ground for proper
operation of the control and flame- -sensing electrode.
The 24- -v circuit contains an automotive- -type, 3- -amp. fuse
located on the control. (See Fig. 24.) Any shorts of the 24- -v
wiring during installation, service, or maintenance will cause this
fuse to blow. If fuse replacement is required, use ONLY a 3- -amp.
fuse. The control LED will display status code 24 when fuse
needs to be replaced.
Proper instrumentation is required to service electrical controls.
The control in this furnace is equipped with a Status Code LED
(Light- -Emitting Diode) to aid in installation, servicing, and
troubleshooting. Status codes can be viewed at the sight glass in
blower access door. The furnace control LED is either ON
continuously, rapid flashing, or a code composed of 2 digits. The
first digit is the number of short flashes, the second digit is the
number of long flashes.
For an explanation of status codes, refer to service label located
on blower access door or Fig. 44 and the troubleshooting guide
which can be obtained from your distributor.

For Controls With an Amber LED
The stored status code will not be erased from the control
memory, if 115- - or 24- -v power is interrupted.
1. To retrieve status code, proceed with the following:
NOTE: NO thermostat signal may be present at control, and all
blower- -OFF delays must be completed.
a. Leave 115- -v power to furnace turned on.
b. Remove outer access door.
c. Look into blower access door sight glass for current LED
status.
d. BRIEFLY remove insulated terminal wire from the draft
safeguard (DSS) switch until LED goes out, then recon-
nect it.
NOTE: If wire to LS or DSS is disconnected longer than 4 sec,
main blower starts, and status code is overwritten with a limit
circuit 33 code.
2. When above items have been completed, the LED flashes
status code 4 times. Record this status code for further
troubleshooting.
3. Check LED status. If no previous faults in history, control
will flash status code 11.
