Hello,I have a 6 year old whirlpool electric range wfe540h0es. I was getting the F3E2 error at high temperatures. I bought and replaced the oven temperature sensor which was very easy to do. Right after, the oven wouldn\'t pre heat and then I got the f3e1 error. I tried putting the old sensor in with no luck. I tried plugging/unplugging and turning off at the breaker. The range elements still work. What next?
