I have a Whirlpool Gold Self Cleaning, Accubake System Electric Range/oven. Model GJP84200, Serial # IMK1256200, Type 30P, 250V, 45.5 Amps, 60 Hz.
All of the digital controls appear to still all work fine, the top cooking elements all still work, so does the Broiling element inside the oven. While cooking a Turkey, it appears that the bottom element ? or maybe the Thermal Fuse on the back of the oven blew ? How can I detect what the problem may be ?
You can still turn the oven on and it will pre-heat and look like it's working fine, but if you stick your hand inside just above the bottom of the oven, it's not scorching hot like the top element is.
