Chefman Voltage Drop / Power Supply Instability

Display and lights flicker or dim when the heater cycles on.

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

Weak internal power supply capacitors, Loose AC connections, Undersized extension cord, Shared circuit overload

Safety first: Unplug before opening the unit. Avoid overloading electrical circuits.

Direct outlet: Plug the fryer directly into a wall outlet without an extension cord or power strip.
Dedicated circuit: Avoid running other high-wattage appliances on the same circuit.
Inspect internal connections: Check AC input terminals and neutral connections on the control board for looseness or heat damage.
Power supply capacitors: Inspect capacitors on the control PCB for bulging or leakage. Replace the control board if capacitors are failing.
