Do-It-Yourself Story

As an FIY, I experienced this problem about 5 years ago and replaced the Digitron (AP3883432) which solved the problem then. This time, I thought since the same symptoms (flickering of the readout and panel shutting down from time to time) that the same part had to be replaced. I ordered and replaced that part but only got a slight improvement in that the panel flickered a little less and shut down less but still had the problems occur. I will say that the readout is much brighter than before so it probably would have had to be changed out eventually anyway. I read through the reviews and noted a response from someone describing similar issues but did some checks and found that the Transformer Power and Power Board needed to be replaced. He mentioned a couple other parts but didn't say why he had changed them out so I elected not to spend the extra $200 on parts I may not need. While I waited for the parts to arrive (took about 10 days to get to Hawaii) I studied the schematics provided on the site and noted that it wasn't going to be too much more work to replace than the digitron. All I needed was a couple of phillips screwdrivers, one short and one long nose. Would recommend the long nose one to be magnetic to help remove and install 2 screws you need to get to through a hole on the top where you have no way to use fingers to help secure. A small flathead screwdriver also helps in prying some of the wiring connectors. First and most important thing to remember which I did was to switch off the breaker switch and make sure no electrical power is going into the oven. I'm not an electrician so I took lots of before shots on my cell phone of the wiring before I disconnected. That way when I put them back, I knew I got them hooked up right. Also, I made sure to secure all the little screws in a plastic bag when I removed them. It's easy to lose them if they fall between the walls of the panels. There will be 9 screws (or maybe 11 can't remember) to remove the front/top readout panel. Once removed, only need to remove the wiring from the connectors. Before I did, I took lots of photos and then carefully removed each one by hand. Might need to use that small flathead screwdriver to help lift some of the wires from the connectors. Once I got the wires removed, I was able to take the panel to my workbench and replace each of the components. Each one required the removal/reinstallation of 4 screws with no problem. Once again, I did take photos before I removed each component and referred back to check I had the connections right once I had it back together. I reversed the entire process for reinstallation. Just made sure that I used that magnetic Philipps screwdriver to reinstall 2 screws on the top. There is no other way you will be able to get those in without it. I know this because I lost 4 screws trying to do it the first time without it. They are somewhere deep down between the panels in a place I'm not ever going. Once everything was together, I turned the breaker switch back on and "presto" "SUCCESS" Just like a brand-new oven. Everything works just fine with no flickering or shut down. This was a fairly easy repair. The key is to be patient and methodical. Don't try to rush or force anything. Keep your screws and tools organized and this should be a breeze for even a newbee.
