B. Secondary Power
1. Verify voltage on the primary side of the main transformer
(High Voltage Machine Only) located at entrance base of the
oven. This voltage should be equal to the machine incoming
voltage (
See Figure 2 ).
2. Verify 240 volts on the RED # 53 and RED # 54 wires on the
transformer secondary. ( See Figure 2 ) A lack of voltage
could indicate a faulty transformer that should be replaced.
(For low voltage machines, verify power between circuit
breakers Q27 and Q28. It should be 208-240V) Note: If
machine is 208-240V, no transformer is required.
3. Check for tripped circuit breakers Q27 and Q28 located on the
upper row of circuit breaker’s on the left side of the electrical
panel. Check for blown fuse for UL machines.
