Depending on the ingredients, there is no problem. Try not to overload the basket so that the temperature does not lower in excess.
Possible cause: Power failure. Check power cords, control thermostat, safety thermostat, ON/OFF switch, contactor, circuit breaker and fuses.
Possible cause: Faulty control thermostat. The thermostat fails to work properly, the temperature keeps rising and the safety thermostat shuts down the machine. If the safety thermostat opens the circuit once and again, it must be replaced.
Possible cause: Control thermostat or fuse have been replaced and calibrated using parameters that are not the same as those used by manufacturer. When thermostats work for a long time, the temperature range may vary. Oil and fats can gather around fuses and probes, causing temperature variations.
Oil should be filtered daily.
