TRANSFORMER
The transformer (See Fig.25) reduces the main power
supply voltage (115 VAC) to 24 VAC. The 24 VAC is sent
through the thermostat (if used) or directly to the
ignition controller. Once the igntion controller receives
24 VAC, an ignition cycle begins. The red LED will come
on.
If the transformer is receiving 115 VAC, but 24 VAC is
absent from its output terminals, the transformer is
defective. The heater will not operate, nor will the red
LED on the burner box door be on.
