The Tempstar models covered in this manual come supplied with various heaters, depending on the characteristics of the machine.
To ensure that you order the correct heater for the model you are servicing, please refer to the following table:
This unit has a probe-direct sensing type thermostat with fixed set point and adjustable range for both wash and booster tank heat reg-
ulating. The same type thermostat is used as the high limit sensor for the wash tank heater. It operates a precision single double throw
switch through a lever for close tolerance narrow differential switching capability. The unit has screw driver adjustment and front con-
nect terminals and is mounted by 7/16”-24 thread, Loxit fitting for easy removability and serviceability. The thermostat range is from
140°F to 240°F with a maximum bulb exposure temperature of 300°F. Unit is listed at 12.5 amps at 24/120 VAC.
There are three (3) thermostats on the dishwasher. One monitors the wash tank temperature, the second monitors the rinse water tem-
perature with the third protecting the heater element. Although all are identical in appearance there are different replacement part num-
bers depending on the function of the thermostat.
Calibration:
The hi-limit thermostat is used to protect the heater element in the event of a run away regulating thermostat or a dry fire situation. It
is set for 210°F +0 or -10°F with a fixed set point.
This part is not adjustable.
The wash tank regulating thermostat will maintain the correct wash
water temperature to meet NSF requirements. These specify that the
wash be no lower than 150°F. It is set at the factory to energize the
tank heater at 155°F and de-energize at 167°F.
The rinse tank regulating thermostat will maintain the correct rinse
water temperature to meet NSF requirements. It is factory set to ener-
gize the rinse tank heater at 195°F and de-energize at 200°F.
To order the thermostats:
Thermostat, High Limit 5930-121-71-36
Thermostat, Wash Tank 5930-121-67-72
Thermostat, Rinse Tank 5930-121-71-29
The models covered in this manual come supplied with various wash motor assemblies (a wash motor assembly includes the wash
motor and the pump end), depending on the characteristics of the machine. To ensure that you order the correct wash motor assem-
bly for the model you are servicing, please refer to the following table:

Important note: When servicing a wash motor,
it is important to refer to the wiring schematic
found on the motor, to ensure that the motor is
wired correctly. Different manufacturers of
motors may not use the same wire color codes
and therefore, your new motor, which may have
been built by someone different than who built
your original motor, may not connect using the
same wires. Always refer to the wiring diagrams
on the motor you are installing. If the motor you
are installing has had the schematic removed,
contact Jackson MSC immediately for technical
support.
