I ordered the control panel and switch membrane. Replaced the control panel and microwave works great! I'll be keeping the switch membrane just in case we have any more issues with our microwave. Shipping was insanely fast, ordered on a wednesday during lunch hour and received the parts the next day before lunch and hubby had the install done in just a few minutes!
