Moderate (electric ovens only). Start with: test the probe; gas oven?. Always, if it's a gas oven.
Is F1 on an oven worth repairing?
Worth fixing. The probe is a cheap part, and ovens outlast almost every other appliance in the kitchen.
About this code
Unbranded and less common appliances don't publish one shared code list, so this page gives the most common meaning across makers. Your manual is the final word, and the model number that finds it is on a label around the oven door frame or on the back.
