A Hobart 00-942185-00002 Hi Limit Switch/Thermostat cuts power at unsafe temperatures to maintain safer, more controlled performance.
The hi limit switch/thermostat monitors dishwasher operating temperatures and interrupts the circuit when heat rises beyond a safe limit, protecting critical components from overheating. Its manual reset design adds an intentional safety checkpoint after a high-temperature event, which supports reliable operation by requiring inspection before the equipment returns to service.
The hi limit switch/thermostat may be approaching replacement if the dishwasher experiences unexpected shutdowns, inconsistent heating protection or repeated manual reset trips during normal operation. Physical signs can include visible wear, discoloration or damaged terminals, while environmental signs may include exposure to excessive heat, moisture or residue buildup that could affect switching performance.
