My mother in-law who is 73 years old bought this less than a year ago and the keypad for the oven stopped working altogether and an error code of CF-2 displayed on the screen. We followed all the user manual troubleshooting steps including the ones on page 44 for shutting off the power and non of these have worked. This was a very expensive oven, especially for a retired person on a fixed income. It's now been 2 weeks and my mother in-law has a zero functioning oven.  Looking for a replacement mother board or replacement oven to remedy this. I strongly recommend not buying this model of oven to anyone looking because the motherboard has a serious bug that makes the entire oven defective after less than a year.
