Blackcomb controllers can be programmed to private brands for individual customers. If a controller is programmed to a private brand, the controller will require a lamp that matches that brand. Installing the exact part number listed on the system is the best way to ensure this issue does not occur.

Note: Blackcomb branded controllers will not experience this issue.


“LAMP KEY INVALID” is displayed.


Cause of alarm: The installed lamp is a different brand than required by the controller.


Recommended Actions:

1.     Check the part number on the lamp key to ensure the correct lamp is installed. Blackcomb - How to Find Replacement Parts

2.     If the part number does not match, install the correct lamp.

3.     If the part number does match, please submit a ticket for support. New Ticket
