Ambiano Timer / Clock Circuit Error

Air fryer runs but time does not count down correctly (too fast or too slow).

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 oscillator on main PCB, Firmware bug, Electrical interference, Failing microcontroller

Safety first: Unplug the unit before PCB inspection.

Step 1 – Verify with external timer: Run a 10‑minute cycle and compare with a separate clock. Note any discrepancy.
Step 2 – Power reset: Unplug for 10 minutes and retry. Minor glitches may clear.
Step 3 – Inspect PCB: Look for damage near the crystal oscillator or timing components (if visible).
Step 4 – Replace PCB: Because timing is controlled by the microcontroller, the practical repair is to replace the main control PCB if the timer remains inaccurate.
