Tub Thermal Cut Off (TCO)
If the thermal cut off (TCO) is open, the thermistor
must be checked. If the thermistor checks good,
then the water level should be checked. A low
water level may cause overheating of stainless-
steel tubs. The TCO is located on the right side
of the tub, approximately 16 inches from the front
of the tub.
The TCO is in a series circuit with the Calrod
Heater.
Tub TCO Location
No water or low water may cause the Tub TCO
to trip. Always check for proper water level if the
TCO is open.
The TCO is secured in place with a slide-in
mounting clip.
