Nice opener intermittently stops responding to all controls until power is cycled.

Safety first: Turn off power before inspecting the opener.

• Check ventilation: Ensure the Nice operator housing is not covered with insulation or stored items and that air can circulate.
• Inspect for heat damage: Look for discolored or burnt components on the board.
• Power quality: If possible, connect the opener to a clean power source or surge protector. Avoid sharing the circuit with heavy loads that cause voltage dips.
• Firmware reset: Perform a factory reset and reprogram the unit. If lockups continue, the control board likely needs replacement.
