gas furnace problem
I have an Amana furnace that is about 7 years old. Last winter it started acting up a little. It would light then go out then relight and stay lit. Now that cold weather has set in again I turned the heat back on and now it won't stay lit for more than a few seconds at a time. The ignition system seems to be working fine but the burners won't stay lit. The furnace is equipped with a diagnostice baord that explains a flashing L.E.D. The L.E.D. flashes one time after powering it up. The explanation says "lock out and check furnace". Thanks for any help.

Hello: Dallas 52
Chances are the pilot flame sensor is dirty and or defective. Carefully use a piece of sanding paper or steel wool and gently clean the elements surface.
Be sure to actual pilot flame is burning HOT and directly contacting the flame sensor element. An all blue flame is required. If there is any visable signs of YELLOW to the flame, air blow the entire pilot assembly to clearout and dust or lint.
Also check the pilot flame sensors electrical connections. Clean as required to insure a good connection. Both of these 2 steps should or could correct the problem. If not, it's possible the part is defective and needs replacing.
Another possibility could be the power exhaust fan not operating or there is a restriction in the venting system. Venting system also includes the vent cap on the flue pipe on the roof.
Suggestions:
Read the manufacturers online web site for product information, problem possibilities, causes and solving methods, part locations, disassembly, reassembly methods, repair proceedures and instructions, pictorials and schematics, which may be available online.
