Product review (2 stars): Persistent faulty electronics, including replacement parts
We're on our third motherboard, less than two years after a purchase, and still having problems affecting the oven. It will either not come up to the preset temperature (the unit will either announce it has reached the target temperature or simply never do so), or reach the target temperature without giving any indication of having done so (including the digital display showing that it's still preheating), the analog thermostat will not show the temperature, or the digital display locks up. So far, power-cycling the unit has restored it to normal operation for a few days until the next problem crops up.
