Midea Timing Circuit / Clock Error

Timer counts down too fast or too slow compared to real time.

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 glitch, Power supply instability, Main PCB microcontroller fault

Safety first: Unplug before internal inspection.

Step 1 – Verify symptom: Use a stopwatch to compare the air fryer timer to real time over several minutes.
Step 2 – Power reset: Unplug for 10 minutes and retest; minor glitches may clear.
Step 3 – Avoid shared circuits: Plug into a stable outlet without heavy loads that may cause voltage dips.
Step 4 – Replace PCB: Persistent timing errors usually indicate a main PCB fault; replace the board.
