Do you get a faint gas smell as well
Thepart you need for the oven is # XXXXX And its about $ 50.00.I think here the parts are a bit cheaper
On the diagram I sent you is the Glow Coil .
That is the part you need to replace for the temp problem
That part goes in the oven, Its what lights up the gas and gets the temp up to what you set
Would this part still need to be replaced if we are getting heat, although not consistent heat? We set the oven @ 530 and it pegs out at 600+. then turn it down to 450 and an hour later it's only 200.
Theres two listed ,Here they are here
