To test the heater, turn the thermostat to the highest setting, typically 90° F.
• If the heater does not turn on, inspect the wiring and ensure the heater is connected.
• If the heater is connected, but not functioning, call the NOC at 1-877-DAK-HELP
(325-4357) to troubleshoot the issue or order a replacement heater.
To test the a/c unit, turn the thermostat to the lowest setting, typically 50° F.
• If the a/c does not turn on, inspect the wiring and ensure the a/c unit is connected.
• If the a/c unit is connected, but not functioning or cooling, call the NOC at 1-877-
DAK-HELP (325-4357) to troubleshoot the issue or order a replacement a/c unit.
Sometimes the heater or a/c can become disconnected from the power source. If you notice
this in a control cabinet, call the NOC at 1-877-DAK-HELP (325-4357) to help Daktronics
track the issue. Refer to the control cabinet Riser Diagram attached to the display door to
reconnect the heating and cooling equipment in the control cabinet.
6.8 Structural Inspection
Perform annual visual inspections of the display structure to facilitate repair and lengthen
display life.
• Check for possible corrosion, especially at structural tie points and ground rods.
• Check, tighten, and replace fasteners as required.
• Check electronic components for corrosion.
• At least once a year check the inside of the display for signs of water intrusion. Water
can enter the display where weather stripping has deteriorated or where fasteners
have loosened.
