Hamilton Beach Intermittent Power Loss / Thermal Cutout

Unit shuts off unexpectedly in the middle of a cooking cycle (no error code).

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

Loose power cord connection at base, Intermittent internal fuse or thermal fuse, Overheating causing thermal cutoff to open, Failing main control PCB

Safety first: Unplug before inspection.

Check cord fit: Ensure the power cord is fully inserted into the cooker and wall outlet.
Ventilation: Make sure the cooker has adequate space around it for airflow and is not enclosed.
Inspect thermal fuse: Test the thermal fuse for intermittent behavior by gently flexing wires while checking continuity. Replace if unreliable.
Control board: If power loss occurs without overheating, the main control PCB may have a failing component and should be replaced.
