I need the flash codes for a model DGAA56BDTB 4 green flashes means what
Type of HVAC: Heater & Furnace
Hello,Is the main blower running while the light blinks 4 times?Billy
yes it is
Thank you.Steady light on - normal operation. One flash - ignition failure. Two flashes - combustion air switch stuck closed. Three flashes - combustion air switch failed to close. Four flashes - limit switch open. Five flashes - gas valve energized with no call for heat. Rapid flashing - reversed polarity. In your case it means a switch overheated during heating cycle.Is/was the filter plugged?
orginal code indicated needs filter, to me it didn't look real dirty or plugged
Ok,See page 22 here for the limits. One style is a push button reset and the other is auto reset. Sometimes the auto reset sticks and doesn't reset itself. In some cases tapping it will reset it...if not you will need to replace the switch.The manual I sent will give part numbers.Link -http://www.winfieldsupply.com/images/HVAC/dgaainstructions.pdf
