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.
