Do-It-Yourself Story

After testing the RTD/temperature sensor, which seemed to work as expected, I replaced the controller. It would have been very easy to swap out the controller (less than 15 min.), except that the replacement controller didn't come with a cover on the touch panel. Rather than try to peel off the old cover and stick it on the new panel, I re-used the old touch panel. This means I had to remove the two PCBs from the casings of both the old and new controllers and swap them around. It took nearly an hour to get everything back together and cleaned up. I was disappointed that an oven only 2 or 3 years old would need a new controller, but it's working properly at the moment, and hopefully will continue to do so for at least several years.
