Sounds like the Start capacitor might be shot.  I think  you need a professional to service it.

On the heating side this happens if you are having a problem with the high limit switch. The unit will heat up and burners will run for awhile,shut off and the fan switch will close and run for ever to cool the heat exchanger down.Make sure the filter is clean and there is a reset button on the system could be in the blower compartment.When you find this, reset it and you should be fine.If this doesn't take care of it, you may have to replace the main control board. Its to bad the Schematic is gone, it would tell you what the 2 flashes mean. You may want to check with the dealer on this unit if you cant find the reset,and they can look this up for you. Just give them all of the numbers,model, serial, and product if there is one.
Good Luck, Shastalaker7
ps, I have seen this fan switch trip and run so many times. It is set up to do this if it senses a build up of heat.

SOURCE: my nordyne e2eb elec furnace keeps blowing the #3 atc fuse

Hi, if it keeps blowing this control fuse, you have a dead short on your secondary side, low voltage, 24 volt side of this unit.Look at the thermostat wire at the unit where you are to see if any thing is scored and touching metal. Every part that operates on 24 volts such as a pressure switch, thermostat, flame roll out switch, and even the coil on the contactor that starts the compressor could be shorted. This is a package unit, 3 and a 1/2 tons.Take the low voltage wires loose from the unit and see if the fuse holds. If it does, you have a short in the stat wire any where from there to the stat. If not, most likely the control board is bad. Take out the screws after killing power and work the board out slowly to see the back of it. If its shorted you will see hot or burned spots on it. Its a process of elimination on the low voltage componants. Please let me know how its going, I will be here to help.

SOURCE: Gibson Furnace /c Nordyne 624631-A board, red LED flashes twice. No heat being produced.

Gas or electric? If gas make sure the line is on by checking the valve. If electric check your breaker panel box and see if it is tripped. If so reset the breaker.

5 flash code nordyne 624631-B Mother board


You should have a sticker on or in the furnace explaining the codes...he threw the PANEL away???..You should always have the panels on the furnace....The codes can also be found in your owners manual for the furnace.....also sometimes there's a legend right on the board itself....More info is required....Turn the power off and back on after a few seconds...observe and write down exactly what happens...I will be able to tell you the problem with detailed "Sequence of Operation"

I have a intertherm model feh-017h electric


It's the heat kit in the unit that is causing the problem. You need to do a continuity test on it to eleminate that they have shorted. This is the only thing in an electric furnace that will blow a fuse on it. Intertherm is a Nordyne product for manufactured homes. Of coarse they still sell them! I am a Nordyne dealer. Also a sequencer can not cause a fuse to blow. The service guy just wants to make money from you by installing a new unit. You can either re-wire the heat kit or you can purchase a new one and have it installed. If you are referring to the heat kit for 159.00, then that's a fair price for it if you are a non licensed person.
