Good To Know

Q: Do I need to match the board number exactly? A: Confirm your unit accepts the PCBDM133 or PCBDM133S board before ordering, since revisions can vary by serial number. Q: Can I install this myself? A: It connects with low-voltage wiring, but a qualified HVAC technician should handle installation to ensure proper defrost operation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
