We have a Tappan/Visualite Wall Oven. The timer area has been ticking/buzzing/annoying me since 2003. The inside metal plate reads as follows: 2200W 230/240 Cat No: 05124 Made in USA 1-63 There are other numbers on the outside/bottom of the oven which read: EOV16V 106840?? Can't really make them out. Can you please help me with disconnecting the timer, and directing me as to where I can get a new heating element as anything baked on the bottom rack is starting to burn. Thanks!
