I'm hoping someone can help me to figure whether to try to repair the oven or cave in and buy a new one.

There are no error codes, the stove-top elements work perfectly, the upper elements in the top & bottom ovens work perfectly. The lower elements are not working in either oven even after having been replaced. Bottom oven elements tested: the upper element read ~10 volts, lower ~ 3-4 volts.

If anyone has any suggestions/advice on what my next steps in terms of diagnosis or parts replacement I would greatly appreciate it!
