Checked AppliancePartsPros.com for similar customer problems after talking to a local appliance store repair technician I told him I had a f1 code and he told me the main control board was shot and the parts were no longer available. He suggested a new stove.I looked up the symptoms on your website and one customer said he had the same code he said he changed the temperature sensor and fixed the problem. I changed the heat sensor and also the heat element seeing that it was 24 years old. Works perfect thanks AppliancePartsPros.com for having the correct parts and fast shipping!
