Transformer Circuit Breaker (Fig. 14)

The unit transformer contains an automatic-reset overcur- rent protector for control circuit protection. If this device trips, it may reset without warning and start the heating or cooling section of this product. Use caution when servicing: If overcurrent protector continues to trip, there is a problem in the low-voltage electrical circuit (i.e., electrical short, ground or transformer overload). Disconnect power, correct the con- dition, and check for normal unit operation.
