I Have Stove- Oven Model Plef398aca From Frigidaire

Hi I just want to know if this appliance is in a recall list. Since I bought this appliance I have had serious problems with it. The appliance continuously shows an error "F7" and starts to beep and flash all lights and numbers on and off. I just got it serviced on 1-2010 and they (Electrolux) said it was just one part that was on recall. The problem was fixed temporarily but it's back.When I called back to Electrolux, they said that as the range was serviced once; they can not give me the service back. This range obviously has a manufacturer defect which  was not solved with a part replacement. I will like to buy a new range, but this one besides that is in perfect condition because it has little use. Please advise me of what can I do with it???
