Do-It-Yourself Story

First I replaced the flickering digitron after reading elsewhere that it may be just a weak display. The new digit on was still flickering but a little differently. Our oven was still working with either display until suddenly it wasn't one morning. After finding AppliancePartsPros and reading that others had to go further by replacing the transformer and power boards, that's when I looked closer at those parts. There was some smoke evidence on the cover over the transformer and the back of two PCBs didn't look as good as the rest. I ended up replacing the Power Board (WB27X10861 / AP3882298), Sub Asm Power Board (WB27X10858 / AP3883396), and the Transformer (WB17X10021 / AP3883205). My old digitron/display may have still been good but I stuck with the new one. I didn't do any actual testing of the old parts, but the visual evidence was enough. As mentioned elsewhere, this is a very DIY job with patience and basic tools. The trickiest part was routing wires. My old power board had lower profile connectors that layed flat on it. The new board's harness connections are perpendicular to the board, but with some careful wire routing, everything still fits fine. Everything works as it should now. The total of almost $600 in parts was pricey but still altogether way cheaper than a new high-end microwave/convection oven for $2400. The very fast shipping helped take some of the sting out of the cost too. I ordered on a Thursday and the parts arrived Saturday. I'm glad I found AppliancePartsPros.com.
