Started by replacing the bake element in the oven but it still would not heat up properly. Then replaced the thermostat and it worked fine. Both of these jobs took maybe 20 minutes combined, but then of course I felt the need to clean the oven while I was in there and that took the rest of the day. LOL I had trouble with the bake element connectors staying on so I took the back off and reconnected them from there, crimping them down tighter with pliers.
