hOmeLabs Latched Control Fault / Overheat Latch

Unit makes ice but then shuts off and will not restart until unplugged

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

Control board firmware lockup, Overheat sensor latching, Faulty thermistor, Power supply instability

Safety: Unplug before inspection.

Steps:

Allow cool-down: Let the unit sit unplugged for 30–60 minutes, then restart and observe.
Improve ventilation and clean condenser: Reduce overheating risk.
Check sensors: Inspect thermistor connections on the evaporator and ambient sensor.

If the unit repeatedly requires unplugging to restart, the control board is likely failing and should be replaced.
