HelloCustomer This is what i am finding on this stove.
We're sorry. No serviceable parts are available for this product.If you need more help, contact us.
I did a little checking and cannot even find parts for it. There is a couple of after market clocks but there over $400 dollars in cost. I think on this one it has served you well and you should enjoy picking out a new 1. Hope this helps. And sorry to be the bearer of bad news.
At the age of the unit cost to try(because there are really no parts anymore) to repair outways the replacement cost. In this case yes you have multiple things going and sevral others will soon follow. Time to throw in the towel.
