We originally hired an appliance repair service, and they diagnosed the issue. The company was supposed to give us an estimate before they ordered the part, but instead they ordered it first and called us later, threatening to charge us for the part when we declined to schedule the repair. A quick Google search brought us to appliance parts pros, where not only was the part much cheaper than the local company wanted, but a repair video gave us the confidence to attempt the repair ourselves. The part arrived in two days. We took the back panel off the oven using a square head drill bit. Once the panel was off, we unplugged every connection from the old control panel, with the exception of the grounding wire. We had to first unscrew and remove the old control panel in order to work the grounding wire off with a butter knife. Then we pulled off the front display panel and used the adhesive already on it to attach it to the new control panel before screwing in the new part. Plugged everything back in, reattached the back panel, and started it up. We then celebrated saving $100 by successfully completing the repair ourselves.
