The E1 - F1 error code indicates that you have an internal memory failure in the clock control board. Unplug the range for 3 minutes and then plug it back in. If the error code returns after plugging the range back in, then the clock control board will need to be replaced. If you want to fix this problem yourself, you can order that clock control from the
website. Use the full model number of your range to order the correct clock control. I suspect that the part number will be 8522442R based on the partial model number that you provided. Here is a link for a video that shows how to replace that part:

Be sure that you
unplug the range
before accessing internal components.
If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
