F1 Error on Frigidaire Professional Range PLEF398CCC

Hi - I had a short circuit that burnt out my clock/timer board on our range. The board shot a flame out and all power to the stove went out. The breaker never tripped so I think the issue originated in the stove. The part was charred when I took it out. I replaced that part AP3215567 and everything seemed to work great. Then last night I received an F1 error and it keeps coming back. I have been able to use the cooktop but havent tried the oven. An F1 error indicates a problem with the part I just installed so I am lost. Is there another part I should be looking at to cause this error? Temp Sensor? http://www.rcappliancepartsimages.com/dbImages/00001633/00492350.jpg

More info: I just verified that I am able to use all functions on the stove, convection, bake, broil, all stove top elements. Just every now and then I get the F1 error. It is very random, sometimes when I hit bake, sometimes when I hit cancel/off, other times it just goes off when I’m not using the stove. Could it be a bad EOC?

Any help would be appreciated.

Thanks,

Andrew
