CONTROL TRANSFORMER (T2) VOLTAGE TEST (continued)
FIGURE F.2 – CONTROL TRANSFORMER X1 AND X2 TEST POINTS
5. Locate Control Transformer leads X1 and X2 at
in line connectors. See Figure F.2.
6. Apply power and test for 115 VAC between
leads X1 to X2.
7. If 115 VAC is not present between leads X1 and
X2, test for correct main AC input power to the
Control Transformer primary windings (H1, H2,
H3, etc.) See Wiring Diagram.
If the correct main AC input power to the Control
Transformer is present, and the secondary voltage
is not correct, the Control Transformer may be
faulty. Replace.
