New homeowners problems

Hello all, we are more or less new homeowners (for the last 2 years). Both of us are working hard to build the home of our dream. We save for most of the stuff and oven was the thing of my dream. But today I saw it stopped working and warranty won't cover fixing it because there is problem with electricity. It's Christmas time around the corner, so I won't be able to do any pies for relatives. It really makes me sad. If there are people who can help me to get a new oven before Christmas - it would be more than just a mirracle.
