Action Needed - Field #
- Be sure terminals are tight. Repair burnt wires accordingly.
- If wires check out, use a Volt meter to check for power on both sides of the transformer. Between black and white wires should read 110-120VAC. Between the black w/white striped wires should read 24-26VAC. From each black w/white striped wires to the brown wire should read 12-13VAC.
- If none of the voltages are read, replace the transformer.
