This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty crystal oscillator on PCB, Firmware timing bug, Electrical interference from nearby devices, UI encoder misreading

Safety: Unplug before internal inspection.

Basic reset: Unplug for 10 minutes and retry to clear any temporary MCU issues.
Test with short cycles: Run a 5‑minute cycle and time it with a stopwatch. If the error is consistent and significant, the timing circuit is faulty.
Reduce interference: Move the fryer away from strong RF sources (Wi‑Fi routers, microwaves) as a test.
PCB replacement: Persistent timing errors usually require replacement of the main control PCB.
