Just had goodman furnace installed. its 95%effiecient . i set the thermostat at a certain temprature when it reaches it the furnace shuts off like it suppose to . the temp drops furnaces won't kick back . the board is flashing 1 single flash. reset the furnace then does it again
1
1 FLASH
Furnace fails to operate.
• Integrated control module
diagnostic LED is
flashing ONE (1) flash.
• Furnace lockout due
to an excessive
number of ignition
“retries” (3 total)1.
• Failure to establish flame.
Cause may be no gas to
burners, front cover
pressure switch stuck open,
bad igniter or igniter
alignment, improper orifices,
or coated/oxidized or
improperly connected flame
sensor.
• Loss of flame after establishment.
Cause may be
interrupted gas supply, lazy
burner flames (improper gas
pressure or restriction in flue
and/or combustion air
piping), front cover pressure
switch opening, or improper
induced draft blower
performance.
• Locate and correct gas
interruption.
• Check front cover
pressure switch
operation (hose, wiring,
contact operation).
Correct if necessary.
• Replace or realign
igniter.
• Check flame sense
signal. Sand sensor if
coated and/or oxidized.
• Check flue piping for
blockage, proper
length, elbows, and
termination.
• Verify proper induced
draft blower performance.
Check to make sure that it is draining right sounds like a draining problem if water gets in the inducer motor it will not vent the air right and the pressure switch won't close

one flash furnace has to shut off to restart
I have same problem with a carrier furnace.
when the thermostat send a signal to the furnace. it start running and then i see the green light flashing the red light stay on. that indicate a pressure open fault.
